Conservative MPs have published more details of their expenses claims, as part of a drive to increase transparency about parliamentary allowances.

Andrew Mitchell (Con Sutton Coldfield) revealed he claimed £3,230 to help pay a mortgage. MPs who require a home in their constituency and a second home in London are allowed to claim financial assistance for interest on one of their mortgages.

He also spent £1,762 on "media intelligence" services, which monitor the media to find news stories of interest to MPs.

Meriden MP Caroline Spelman, the Party Chair, revealed she had paid an agency £2,937 to produce a pamphlet.

The figures cover the first quarter of the financial year, from April to the end of June.

Party leader David Cameron has ordered all front-benchers to reveal full details of expenses claims, and encouraged backbench MPs to do the same.
