Swindon’s new MPs were paid more than £5,600 in expenses in the first four months of this Parliament.

The information published by Ipsa – the Independent Parliamentary Standards Authority – show North Swindon MP Justin Tomlinson was paid £4,003.52 and South Swindon MP Robert Buckland £1,670,47.

In addition North Wiltshire MP James Gray claimed £11,729.69.

The discrepancies in claims relate to many MPs not being paid or submitting claims at a later date. Claims of MPs for the four month periods are not comparable given they can claim any time in the year.

Details of their post-election claims including second home, travel, office and staff costs were unveiled by the new MPs’ expenses watchdog – set up to enforce tighter rules on MPs’ use of taxpayers’ cash in the wake of last year’s expenses scandal.

A breakdown shows Mr Tomlinson claimed for rent each month at £924, and £240 for second-hand furniture for his office. He also had to pay more than £200 agencies’ fees for the flat.

Mr Buckland also paid £240 for second-hand furniture, £184 for office stationary and £636 for hotel accommodation in London.

Both MPs have claimed for the cheapest available fares to and from the constituency.

Mr Tomlinson said: “As a new MP I am determined to play my part in restoring faith in politics after the disgraceful actions of many former MPs.

“I do not claim for food, mobile phones, travel in Swindon or London, political websites or newsletters.

“In addition to save further money I have shared staff and office and second-hand furniture, travel super saver return and share a flat in Westminster with two other MPs.

“Over a full year my measures will have saved a considerable amount of money and I would fully expect to be one of the cheapest MPs and rightly so.”

Nationally the first set of MPs' expenses under the new rules revealed MPs were paid £3.1m. Some 22,000 claims of 576 MPs were disclosed – indicating that 74 have not been paid as yet.

Although a description of each claim was published, Ipsa decided it would be too expensive for it to release copies of individual receipts. It was that detailed information which allowed some of the previous wrongdoing by MPs to be exposed in revelations which rocked Westminster.

A spokeswoman for Ipsa said: “We are not commenting on individual cases. If an MP has put in claims after August 31 it would not be included in this tranche.”

When asked if the amount was what an MP had claimed for or what IPSA had paid out, she replied: “The figures relate to what we have paid out.”

The figures come as MPs hit out in a Commons debate over Ipsa’s handling of the system.

Prime Minister David Cameron claimed £2,581.13 and Labour leader Ed Miliband claimed £2.066.27.
