David Cameron is to repay almost £1,000 he wrongly claimed on Parliamentary expenses after reviewing his claims over recent weeks.
The Tory leader had already announced his intention to pay back £680 he claimed towards repairs at his second home in Oxfordshire.
But today he wrote to the Commons Fees Office volunteering the repayment of £947.29 - including the £680 for repairs - after identifying a series of over-claims.
Today, Mr Cameron was sending a cheque enclosed in a letter to Terry Bird, the Commons' director of operations.
"Over the last few weeks, I have carefully gone through the claims I have made against the Additional Costs Allowance (ACA) since 2004," he wrote.
"This has brought to light a number of points. I would like to make clear that these were discovered as a result of a thorough review by my office, not as a result of media inquiries."
The additional amounts for which he is reimbursing the Fees Office include:
* £218.91 in mortgage over-claims resulting from "an inadvertent administrative error" arising from changes to his home loan arrangements;
* £9 he was over-compensated for on an electricity and gas bill;
* £10 too much he received for a researcher's phone bill;
* £29.38 he claimed towards a banner on his website he was subsequently asked by the Commons to take down.
Mr Cameron has previously announced that he would be paying back a maintenance bill of £680 for household repairs to his constituency home.
The work included clearing wisteria and vines from a chimney, replacing outside lights and resealing his conservatory roof, according to the Daily Telegraph.
The odd jobs included repairing cisterns, washers and a leaky washing machine.
"On reflection, I would like to repay this bill, even though it was entirely legitimate under the ACA," Mr Cameron wrote today.
