The Keens expenses row has deepened over claims the couple racked up a £5,000 hotel bill in just six weeks.

Ann and Alan, MPs for Brentford & Isleworth and Feltham & Heston respectively, claimed for the stay between April 1 and May 17, 2002. The period reportedly relates to the six-week gap between the duo selling their flat in Covent Garden and buying a luxury flat in Waterloo.

Documents released under the Freedom of Information Act show Ann claimed £2,575 for 'hotel expenses, etc', while Alan claimed £2,425 for 'hotel, telephone, etc'.

The Commons sat for just 19 evenings during this time, meaning the bill for taxpayers works out at more than £260 a night.

The Keens were last week criticised for spending £175,000 of tax payers' money on a flat in Waterloo, despite their Brentford home lying just nine miles from Parliament.

However, there is no suggestion they have broken Parliamentary rules with any of their claims.
