N5,000 note’ll encourage money laundering – Fasehun
 |
| Dr. Frederick Fasehun |
Founder
and President, Oodua Peoples Congress, Dr. Frederick Fasehun, says the
planned introduction of N5,000 note will encourage money laundering.
Fasehun said this during a media roundtable in Lagos on Wednesday.
According to him, imposing the new note on Nigerians would not augur well for the security and social life of the people.
Fasehun said, “Introducing a high denominational currency will lead to inflation.
“Our fight against corruption, money laundering and inflation will end
in a smoke if the CBN goes ahead to intoduce the N5,000 note.”
He wondered why the CBN was insistent on the new note at a point when corruption is widespread in Nigeria.
He said, “What do we want to do with N5,000 note? Ghana, rather than
coming up with higher denomination note when the Cedi was losing value,
downgraded it and it helped her economy to grow.
“We will resist it if the CBN goes through with the new denomination.”
Meanwhile, National Vice-President, the Committee for the Defence of
Human Rights, Mr. Taiwo Otitolaye; Kwara State chapter of Nigeria’s
Political Parties and The Concerned Citizens of Nigeria have warned that
Nigerian may be thrown into another mass revolt over the planned
introduction of N5,000 notes if the Federal Government does not stop the
planned exercise.
They urged the Federal Government and the National Assembly to halt the exercise.
The country had witnessed an unprecedented mass revolt in January over the withdrawal of fuel subsidy.
In a statement on Wednesday, Otitolaye said CDHR would team up with
other civil society groups in the country to ensure that the plan did
not succeed.
He alleged that the introduction of
the N5,000 note was a script allegedly drafted by the International
Monetary Fund, World Bank and other imperialist agencies.
He also said the policy would lead to inflation and urged the National
Assembly to intervene and stop its implementation to avoid another mass
revolt in the country.
Fire Destroys 300 Shops, Property Worth N1bn In Ibadan
 |
Property worth more than one billion naira was lost, Wednesday, as fire gutted Labaowo International Market, off Oke-Bola, Ibadan. A girl was also injured in the fire.
Although, no life was lost, traders whose wares were lost in the inferno that started some minutes past 10am struggled to retrieve one or two things from the burning fire.
When Vanguard visited the market yesterday around 3.05pm, fire was still burning some of the shops. Firemen were seen struggling to put out the fire.
The President of the market, Alhaji Lukman Alaka, told our correspondent that more than 300 shops were burnt.
Items such as electronics, motor spare parts, generator spare parts, building materials and many others were lost to the fire incident.
When asked what caused the fire, he said; “Suddenly, we saw balls of smoke was accompanied by fire. We called all the fire stations close to us, but, the response was not immediate. I called Challenge fire station and another one at Mapo. When I noticed that they were not forth coming, I had to go to Mapo before help could come. But, before we got back to the market, the fire had gone out of hand.
“As for the property lost, it can’t be less than one billion. Many traders were affected. Some could not even retrieve anything from their shops. We would be happy if the government can provide a fire station for us here.”
One of the affected traders, Mr. Tijani Amoo explained that he just took a bank loan worth N800,000 to buy wares lamenting how he would refund the money.
He said he lost all the items. Though, he was not far away from the scene of the fire, by the time he knew, the fire was too much.
The Director of State Fire Service, Mr Kareem Oyekunle said his men battled for long before the fire could be put out. He said as soon as the distress call came, he and his officials rushed to the scene.
Licence Back In Hand, Dana Airline Joins Plot To End Inquest Into Crash
 |
| DANA |
Dana Airline on Thursday filed an affidavit to support a motion to halt the ongoing inquest into the cause of the crash involving its McDonnell Douglas MD-83 on 3rd June, killing all 153 people aboard as well as at least six residents of a building in Iju-Ishaga, Agege.
The affidavit, described by the presiding judge as “a novel issue” comes just one day after the Federal Government lifted an earlier suspension on the airline’s operating licence.
The plaintiffs, Dele Ore and the Civil Aviation Round Table Initiative, want the Federal High Court, Lagos to end the inquest on the point that the Lagos State Coroners’ System Law is inapplicable to deaths arising from aviation accidents.
Joined as the 1st to the 4th defendants in the suit are Oyetade Komolafe, the coroner; the Chief Coroner of Lagos State; the Lagos State Chief Judge; and the Attorney General of Lagos State, respectively.
Also joined as defendants are the Attorney General of the Federation; the Federal Ministry of Aviation; Nigerian Civil Aviation Authority (NCAA); Federal Airports Authority of Nigeria (FAAN); Accident Investigation Bureau (AIB); Nigeria Air Space Management Authority (NAMA); and Dana Airlines.
Delivering the bench ruling, Okon Abang, the presiding judge, said that although there is no provision allowing a defendant to file a motion in support of the affidavit of a plaintiff, the court will rely on it if it will be of use.
“The most important issue is to consider if the interest of the 1st – 4th defendants will be prejudiced,” he said.
“The 1st – 4th defendants are at liberty to file their objection to the affidavit if they so wish.”
He fixed 13th September for “definite hearing” of the plaintiff’s motion for interlocutory injunction.
Ore, a retired pilot, had filed the suit on behalf of the Civil Aviation Round Table, asking the court to pronounce the Lagos State Chief Judge as acting ultra vires by inaugurating a coroner’s inquest into the air mishap.
He argued that the country’s ratification and domestication of the International Civil Aviation Organization (ICAO) Chicago 1944 Act, renders the coroner’s inquest “unconstitutional, null and void, and of no effect whatsoever.”
He equally urged the court to hold that the Coroners’ is inapplicable to aviation-related matters and deaths arising from aviation accidents.
And in their affidavit at the court, Dana Air’s counsel corroborated the positions of the plaintiffs, saying, “The crux of instituting this application is in the sole interest of the public. The inquest ought not to have commenced until the conclusion of the AIB investigation. The coroner has subjected the AIB report to scrutiny by various experts.”

WORLD LITERACY DAY: Is education for all feasible by 2015?
EVER heard the saying that Illiteracy is a disease? Perhaps, that
informed the setting aside of September 8 every year as the
International Literacy Day by the United Nations Educational, Scientific
and Cultural Organisation, UNESCO; an agency of the United Nations
whose purpose is to contribute to peace and security by promoting
international collaboration through education, science, and culture.
It is a day set aside by UNESCO to raise global awareness and concern for literacy problems within communities. So come Saturday, September 8, Nigeria will join the rest of the world to mark the 2012 edition of the International Literacy Day which was first celebrated in 1966 after its proclamation on November 17, 1965.
According to UNESCO, literacy is a human right because it is a tool of personal empowerment and a means of social and human development. Also, because educational opportunities depend on literacy, literacy is at the heart of basic education for all (EFA) and is essential for eradicating poverty, reducing child mortality, curbing population growth, achieving gender equality and ensuring sustainable development, peace and democracy.
As the world celebrates International Literacy Day 2012, it is pertinent to note that though the international community has pledged to improve adult literacy levels by 50 per cent between 2000 and 2015, about 800 million adults – 64 per cent of whom are women – still lack basic reading and writing skills.
Themed: Literacy and Peace, the 2012 International Literacy Day is
aimed at showing how literacy contributes to peace by bringing people
closer to attaining individual freedom and better understanding the
world, as well as preventing or resolving conflicts. The connection
between literacy and peace is that it is harder to establish or sustain a
literate environment in unstable democracies or conflict-affected
countries.
Activities lined up to celebrate the day include high-level international round table on literacy – Reaching the 2015 Literacy Target: Delivering on the Promise, and the 2012 UNESCO literacy prize winners’ ceremony.
There is no denying the fact that quality basic education equips people with literacy skills for life and further learning; literate parents are more likely to send their children to school; literate people are better able to access continuing educational opportunities; and literate societies are better geared to meet pressing development, according to UNESCO.
But despite numerous efforts, global literacy rate looks alarmingly low. According to UN analysis, one in five adults (800 million) is illiterate; 75 million children don’t attend school and many more attend irregularly or are drop outs. In Nigeria, the literacy rate of males between 15-24 years is 78 per cent, while that of females within the same age bracket is 65 per cent.
Speaking in Abuja at a meeting of Education ministers and senior officials from nine highly populated developing countries (E9 countries) of Bangladesh, Brazil, China, Egypt, India, Indonesia, Mexico, Nigeria and Pakistan, Nigeria’s Minister of Education, Prof. Ruqquayatu Rufa’i said E9 countries were still short of their targets years after committing resources to achieve universal literacy by 2015.
“In spite of accelerated impetus to achieve Education for All (EFA) goals by 2015, we still lag behind. One goal is to reduce illiteracy by 50 per cent,” she said.
At least, two in every three illiterate adults or young persons reside in an E9 country, which account for 535 million illiterate people out of the estimated 800 million considered illiterate globally.
EFA’s six goals that countries should target against the 2015 deadline are: expand early childhood care and education; provide free and compulsory education for all; learning and life skills for young people and adults; increase adult literacy by 50 per cent; achieve gender equality in education; and improve quality of education.
With nearly 3.5 billion inhabitants in 2005 – more than half of the world population, E9 countries represent tremendous challenges that weigh heavily on global education trends as most of them are yet to achieve universal primary education and all face major quality deficits.
Of the world’s 800 million adults who lack the basic learning tools to make informed decisions and participate fully in the development of their societies, nearly 70 per cent live in E9 countries.
Tackling the literacy gap is both a moral and development imperative for E9 governments and donor countries. It requires strengthening efforts to expand education and to significantly improve its quality.
This, Rufa’i agrees with, as she pointed out that for E9 countries to achieve the level of literacy required, there is need to reach out further to those living in remote and rural areas and very difficult terrains, women, youth and the marginalised.
Bringing it closer home, she said one of the programmes through which Nigeria can up her literacy rates is being implemented in collaboration with UNESCO through a self-benefiting Funds-in-Trust valued at over N1bn.
“We are now in a better position to address the challenge of illiteracy with a renewed commitment and a sense of urgency and we expect that the programme will yield remarkable outcomes before 2015,” she enthused.
Though some considerable successes have been recorded since efforts were first made in 1944 to address the issues of illiteracy in the country, but the challenges are quite daunting. Nigeria, presently, has over 50 million illiterate citizens which, to a large extent, has impacted negatively on all facets of national development and has led to civil unrest in some parts of the country.
As it stands, Nigeria might still miss the 2015 target date of reducing its illiteracy rate by 50 per cent under the EFA declaration made in Jomtien, Thailand in March 1990.

FG approves contract on Benin-Sagamu Phase 3
The Federal Executive Council yesterday approved the reconstruction of outstanding sections of Benin-Ofosu-Ore-Ajebandele-Shagamu expressway phase 111.
The contract which was awarded in the sum of N65,223,155,642.34 with a completion period of 36 months, according to Minister of Information Labaran Maku “will not only improve the socio-economic activities of the area, but will also reduce vehicle operating costs, travel time and accidents on the road”.
The Minister who was flanked by his colleagues, the Minister of Works, Mike Onomelemen and Minister of State for Federal Capital Territory, FCT, Olajumoke Akinjide, said the “outstanding sections of the road are in disrepair’ there is need to reconstruct them to ease traffic flow along the road.
He said when completed, the project will generate employment for Nigerians as well as impact positively on the informal sector of the economy.
Speaking on the project, Mr Onolememen said the scope of work would include the complete reconstruction of Km 9 to Km 18 and Km 75 to Km 162 of the road, adding that it would have three lanes on both carriage ways at the completion of the project.
Other approvals granted by the Council include the purchase of various search and rescue operation items for the National Emergency Management Agency, NEMA.
Some of the items include a GSSI life locator, in the sum of N161,406,388.00; rapid intervention vehichles, in the sum of N400,551,272.00; fully equiped emergency rescue vehicles in the sum of N251,680,000.00; and 328 sets of helmets, harness, lanyards and absorbers, descenders, fall arrestors, ascenders, aluminium and steel carabineers in the sum of N120,227,377.64.
Maku said “the rampant increase in the spate of disasters in the country has continued to stretch the resources of NEMA in terms of equipment and logistics” necessitating the contract.
Others include the construction of Southern Parkway in the Federal Capital Territory in the sum of N10.901,23 billion thereby bringing the total contract sum to N16.235 billion. The Minister said as part of the efforts to reduce the heavy traffic being experienced in the city, the FCTA has embarked upon the construction of the Southern Parkway from the Christian Centre S8/S9 to ring road 1 comprising10 lanes, to complement the existing Northern Parkway. When completed, the Southern Parkway would undoubtedly ease the increasing heavy traffic situation in the Southern parts of the FCT within the corridors of already developed and fast developing districts like Central Area, Garki, Gudu and Durumi.
Council also approved the sum of N2.835 billion for phase II contract for the provision of infrastructure to Apo Estate layout, thereby bringing the total sum of phase I and II to N5.755billion.
The council also ratified the president’s anticipatory approval for the Sagbama erosion control rehabilitation works in Bayelsa State in favour of Messrs Nigerian Westminister Dredging and Marine Limited in the sum of N1.501billion, with completion period of 12 months.
In another development, Council also approved the Good Governance Tour, a non-partisan tour being put together by the Ministry of Information in conjunction with the Nigeria Governors’ Forum to showcase on-going and completed projects across the country.
According to the Minister of Information, the inspection tour will cover the federal and state projects. He announced that it will kick-off on September 20th from the North-Central region, starting from the FCT.
