Married MPs Alan and Ann Keen both claim £17,669 each in expenses for housing – despite living just 9 miles from Westminster. The Labour pair each put in an invoice for for the flat they share in London’s fasionable Covent Garden.

Their main home is in Mrs Keen’s constituency of Brentford and Isleworth, Mr Keen represents neighbouring constituency Feltham and Heston. The backbench pair have broken no rules, although voters may be surprised to learn they claim twice for the same flat.
