The invitation letters, which were sent before the suspension of EFCC chairman Abdulrasheed Bawa, requested the former ministers to explain how they spent funds allocated to their ministries on designated projects.
The sources said that apart from former minister of Women’s Affairs, Pauline Tallen, who was invited last week over alleged N2 billion fraud, about seven other former ministers have also been invited.
Sale Mamman, a former minister of power, was arrested and detained by the EFCC in connection with an alleged N22 billion fraud related to power projects.
Muhammad Maigari Dingyadi, the immediate past minister of police affairs, has also been summoned by the EFCC to provide answers to allegations of purchasing refurbished vehicles for the Nigeria Police as new.
Hadi Sirika, the former minister of aviation, and Abubakar Malami, the immediate past minister of justice and attorney general of the federation, have also been invited by the EFCC.
The EFCC has not yet commented on the invitations.
