Nigeria central bank head Lamido Sanusi ousted

Lamido Sanusi has spearheaded reforms in Nigeria's troubled banking sector since his appointment in 2009

Nigeria's central bank governor Lamido Sanusi has been suspended after he alleged that $20bn (£12bn) in oil revenue had gone missing.

President Goodluck Jonathan said there had been "far-reaching irregularities" under Mr Sanusi's watch.

The BBC's Will Ross in Nigeria says the allegation of missing oil revenue has come as a huge embarrassment for the government.

Mr Sanusi has spearheaded banking reforms since his appointment in 2009.
