A formal investigation into the Keens' expenses by the Parliamentary Commissioner for Standards ruled in March 2010 that the Keens had breached the expenses rules and that he regarded the breach of the rules as "serious", and involving "significant public funds". He suggested that the Keens should pay back four months worth of their claims – some £5,678. However, The Commons Standards and Privileges Committee of MPs took the unusual step of disagreeing with his findings and slashing the repayment ordering them to repay £1,500.
