Stephen Davis, the Australian negotiator who sparked off a controversy by naming two prominent Nigerians as sponsors of Boko Haram, has accused the State Security Service (SSS), also known as DSS, of doing the bidding of Ali Modu Sheriff, one of the alleged sponsors of the terror group.

Davis had in August named Ihejirika Azubuike, former chief of army staff, and Ali Modu Sheriff, former governor of Borno state, as sponsors of Boko Haram. Both denied the allegation.
