ILKESTON: Prime Minister Gordon Brown on Thursday suspended a Labour Party MP over embarrassing expenses claim revelations, in a row rocking all political parties.

The suspension of former agriculture and environment minister Elliot Morley came hours after opposition Conservatives announced the resignation of an aide to leader David Cameron, the first scalp in the expenses controversy.

"Where standards are transgressed and mistakes are made we have got to take action," Brown said, announcing Morley's suspension from the parliamentary Labour party.

In the latest details published by the Daily Telegraph, it emerged that Morley claimed over 16,000 pounds for a home loan 18 months after it was paid off.

While all three main parties have been embarrassed by the row, Brown has been forced to play catch-up after the Tory chief ordered all his lawmakers to repay any dubious expenses money.

Earlier the Conservatives announced that Andrew MacKay, an MP, had resigned as an aide to Cameron after it emerged he and his wife, also a Conservative MP, had claimed expenses for two home loans at the same time.

The row has exacerbated Brown's political troubles as his Labour Party badly trails the Conservatives in polls ahead of elections next year.
