MPs are set to face tougher scrutiny of their expenses following the suspension of a Tory MP who mistakenly claimed over £90,000 for a second home.

Speaking in the Commons, Robin Cook said it is "important that we tighten up the system".

In future MPs may have to provide documentary evidence, such as receipts or bank statements, to verify their claims.

A report by the standards commissioner has recommended that MPs claiming for a second property outside their constituency should specify where the property is and provide documentary corroboration.

"I think both of those would be welcome and necessary steps to tighten up the system and I would be sure and confident that they would achieve very substantial support within the House," said Cook.

He told MPs that following a meeting of the Speaker's advisory panel, the Commons Fees Office would bring forward proposals to tighten the system.

Labour's David Winnick said MPs must be made more accountable for the money they claim.

"I work on the assumption that the overwhelming majority of members on all sides are perfectly honest, but wouldn't it be helpful that any amount being claimed over, say, £10 or £15 the documentary evidence should be provided," he said.

Liberal Democrat MP Mark Oaten called for the system of punishment to be overhauled following the Wicks report into conduct of those holding public office.

He noted that councillors guilty of misusing allowances had in the past been open to surcharge or disqualification.

"There is an inconsistency between the amount of punishment that can be imposed on different forms of democratically elected councillors, and MPs across different offices," he said.

"When the House does look at the Wicks report and looks at the possibility of fining members of parliament I do urge the leader of the House to bear in mind inconsistencies so we have a level of similar punishment for all of us who hold elected office."
