Conservative ex-minister Sir Peter Luff is currently renting a flat owned by Chelsea midfielder Frank Lampard at the expense of the taxpayer.
The former defence minister has claimed that he has been living in the £1,600-a-month flat as opposed to his home in the capital because he could no longer afford the mortgage repayments, which can no longer be claimed on expenses.
"IPSA specified that when MPs are away from home they must live in rented property or stay in a hotel," Luff said on his website. "When I am in London, I now therefore live in a rented flat.
"This is not my preference. I would have preferred to continue to live in the flat I own, but IPSA's well-meaning rules designed to safeguard the taxpayers' interests and promote transparency oblige me to do [this]."
Lampard's flat is situated in Old Brompton Road, West London.
