Nigeria's anti-corruption agency has summoned 15 former state governors for questioning in what could be a litmus test of how seriously the new government takes the fight against graft.
The governors had immunity from prosecution until they handed over power on May 29th. The Economic and Financial Crimes Commission (EFCC) has long accused many of them of looting public funds and complained that their immunity shielded them.
But many Nigerians say the EFCC was used as a political weapon by the previous government, targeting only people who were out of favour. The big question now is whether the new government will give it a free rein to prosecute ex-governors - even those who were friendly with the former president.
"Now they are out of power we need to ask them questions directly," EFCC spokesman Osita Nwajah said today.
"If they are guilty they will be prosecuted."
The 36 state governors are powerful figures in Nigeria, with discretionary powers over millions of dollars of public money.
Until three years ago they were considered untouchable, but since 2004 five have been impeached - two of them after jumping bail in Britain where they faced corruption charges. One of the impeached governors is now on trial in Nigeria.
Former President Olusegun Obasanjo heralded these cases as successes of his high profile war on corruption, but many critics said there were political motivations behind the impeachments. The courts reversed three of them.
