Dawn Butler, a junior whip, claimed almost her entire £23,000 allowance to help to pay for a second home in her constituency in northwest London. Opposition MPs demanded to know why she needed the taxpayer to help to buy another property when she could stay overnight in her family home in East London.
Ms Butler, who has a family home in Stratford, East London, and another in Wembley, in her Brent South constituency. The Stratford property is eight miles and a 24-minute Tube ride away from Westminster. The Wembley house, bought after the election, is nine miles and a 32-minute Tube ride away from the Houses of Parliament.
There are 24 MPs with seats in Greater London who have claimed nearly £400,000 to fund second homes in the latest year for which figures are available.
