TORY backbencher Bob Blackman faces repaying more than £1,000 in mileage expenses after submitting over 700 “inaccurate claims,” an inquiry found yesterday.

The Independent Parliamentary Standards Authority (Ipsa) concluded that the Harrow East MP’s claims were “in almost every instance not accurate and greater than the distance travelled.”

Mr Blackman wrongly submitted claims for travelling from his constituency home to his office and for going to party-political events and canvassing sessions.

One example given was a two-mile journey to Harrow Weald, claimed as 10 miles.

Ipsa had been warning Mr Blackman about high mileage claims since 2011 but did not open a formal probe. But an audit of 2013-14 found Mr Blackman had again racked up the highest mileage of any MP.

He claimed more than 400 miles per square mile of his constituency, almost double that claimed by the next 10 priciest MPs.
