Reforms to House of Commons expenses designed to prevent sleaze scandals will push up the cost to the taxpayer, an MP has claimed.
John Spellar (Lab Warley) spoke out against the changes as new figures showed West Midlands MPs claimed £500,000 in nine months last year.
The figures showed massive variations, with some MPs claiming nearly £42,000 between April and December - while others claimed less than £6,000.
Big spenders included Ian Austin (Lab Dudley North), who claimed £41,891.72 - including six claims of £1,162.88 each to subsidise a mortgage.
He also claimed £7,895.00 to pay for leaflets, newsletters, cards and postage costs.
Mr Spellar claimed just £5,581.48, including four claims of £57.39 to subsidise a mortgage.
MPs have traditionally been given allowances to subsidise the cost of a second home in London or their constituency.
But Mr Spellar warned that reforms, which mean MPs will claim for rent instead, will cost taxpayers more.
The MP, who has represented Warley since 1997, said: “My mortgage is low because house prices were lower when I became an MP. People who became MPs more recently have larger mortgages.
“Renting a property in London is actually going to be far more expensive than the system we currently have.”
Under new rules, every MP will be entitled to up to £17,400 to pay for renting a property in London.
Mr Austin said: “I live in Dudley and all these costs have been to enable me to go to London and fight for my constituents, and keep them informed about the work I have been doing on their behalf.”
