MPS have “lost their moral authority” and should accept the recommendations of a report into their future conduct, according to Worcester’s MP.

Sir Christopher Kelly, chairman of the Committee on Standards in Public Life, will publish a report on Wednesday with proposals to reform the system in the wake of the expenses scandal earlier this year.

Following reports of the review being leaked to the Press, it is claimed Sir Christopher will recommend banning MPs from claiming for their mortgages on expenses.

It has previously been reported how he is also said to be calling for a ban on MPs employing relatives.

Worcester Labour MP Mike Foster employs his wife Shauna as diary keeper and office manager.

He said: “When the report is published we will have to sit down, look at it and see what the implications are. It will be very difficult, given that we have lost the moral authority, to say ‘no, I disagree’.”

Dr Richard Taylor Independent MP for Wyre Forest, who does not employ his wife, said he thought MPs should be allowed to employ their wives.

Dr Taylor said: “Whatever the recommendations are, we have to accept them.

“But I do have concerns about a blanket refusal to allow any MPs to employ relatives. If a wife is employed under the same terms of contract as anybody else it can be a huge advantage for the MP, his wife and their marriage.

“But obviously, the abuse that has occurred in the past has to be stamped out.”

Peter Luff, Conservative MP for Mid-Worcestershire, has previously said he would consider quitting if he was no longer able to employ his wife. Mr Luff has employed his wife as his private secretary for 17 years. He was unavailable for comment yesterday. Sir Michael Spicer, Conservative MP for West-Worcestershire, declined to comment.

Prime Minister Gordon Brown said in the House of Commons yesterday that he hoped a new MPs’ expenses system would be brought in “as quickly as possible”. He said: “I think all Members of Parliament want to bring the old, discredited system of expenses to an end.”
