David Cameron has announced a series of immediate measures to start to rebuild trust in politics and take action on the issue of expenses.
He has banned Conservative MPs from claiming for furniture, other household goods and food shopping; put an end to the practice of 'flipping'; and set up a Scrutiny Panel to review all excessive claims and arrange repayments where appropriate.
In addition, the Shadow Cabinet and the Conservative Frontbench are publishing online all the expense claims they make to the House of Commons.
You can view Shadow Cabinet and Shadow Minister expense claims on their individual profile pages. They have been made available using Google Docs technology, which is an open and accessible format so people can use the information however they choose.
