Moore was head of Group Regulatory Risk at HBOS from 2002-2005 and was responsible for the bank's policy as well as its compliance with the FSA. In 2004 he advised the bank that they should slow down and that they were taking too many risks, knowing that a crisis was realistically around the corner.

He was fired in 2004 but sued for unfair dismissal, winning the case. However, in return for his compensation Moore signed a 'gagging order' to remain quiet. Risking his reputation he broke the silence and submitted evidence to the Treasury Select Committee on February 10 2009.

The chief exec of HBOS, Sir James Crosby, has since resigned while Moore's evidence has been publicly blasted.
