A spokesman for the Economic and Financial Crimes Commission said Wednesday that chairwoman Farida Waziri had been fired. Spokesman Femi Babafemi said Waziri had at least another year left in her tenure.

Babafemi says agency deputy Ibrahim Lamurde has been appointed acting chairman. He said he did not know the president’s reason for firing Waziri.

Waziri and a presidential spokesman could not be immediately reached for comment.

Waziri has been criticized by US diplomats in leaked cables for being unprepared and for apparently being controlled by politicians. Others have leveled corruption allegations against her and operatives of the commission, though none have been proven.
