Nigerian President Goodluck Jonathan on Wednesday sacked four cabinet members including aviation minister Stella Oduah, a close ally, a presidency source said, in the latest of a wave of government changes ahead of elections next year.
He also removed minister of police affairs Caleb Olubolade, minister of the Niger Delta Godsday Orubebe and deputy finance minister Yerima Ngama, the source said.
Jonathan is facing a crisis within his ruling People's Democratic Party (PDP) over his assumed intention to run for another term in the 2015 election. He has yet to say whether he will.
Jonathan dismissed his chief of staff on Monday, after overhauling his military high command last month.
He has been defending his record on corruption this week after a series of graft allegations in recent months.
Oduah stirred public outcry last year after her ministry spent $1.4 million on two bullet-proof limousines, far more than their market value. Opponents have been calling on Jonathan to remove her.
