The trial of Nigeria’s suspended central bank governor, Godwin Emefiele, by a high court over an alleged 6.9bn naira ($9m; £7m) procurement fraud, has again been stalled.

The case was not listed among proceedings at the High Court in Abuja, the country’s capital.

Neither Mr Emefiele’s lawyers nor the prosecutors - the State Security Service (DSS) - were present in court and no reasons were provided for the absence of the case on the court’s case list.

The DSS, Nigeria's secret police, is yet to respond to the BBC’s request for comment.

Last Thursday another attempted arraignment was delayed after a co-defendant, Sa'adatu Yaro, did not appear in court.

Mr Emefiele faces 20 charges brought by the DSS for alleged “procurement fraud, conspiracy and conferring corrupt advantages on his associates”.
