Nigerian President Olusegun Obasanjo has agreed to be investigated by the country\'s anti-corruption body after a governor accused him of taking bribes.
Mr Obasanjo denies the allegations from Orji Uzor Kalu - a member of his own governing party.
They include receiving commissions for oil contracts and holding illegal foreign bank accounts.
Nigeria is considered one of the most corrupt countries, but the president has vowed to fight the problem.
The accusations, described as \"serious\" by the Economic and Financial Crimes Commission (EFCC), are also directed at senators and senior government officials.
\"I authorise you to clinically look into these allegations and make your findings known, not only to me but to the nation,\" the president said in a note to the commission.
Critic
The EFCC was set up by President Obasanjo as part of his pledge to fight corruption after his election in 1999.
Mr Kalu, the governor of the south-eastern Abia state, is also under investigation by the same body.
He has been a vocal critic of Mr Obasanjo, and has announced his intention to run for president in 2007.
This is the second accusation against Mr Obasanjo since he stepped up his anti-graft campaign earlier this year.
Although a number of senior officials have been put under investigation for alleged corruption in recent months, there has not been any significant conviction during his six years in power.
