A second ministerial aide has quit the Government in the space of just two days.

Conservative MP Richard Graham has said he is standing down as parliamentary private secretary (PPS) to the Foreign Office Minister Hugo Swire.

Writing on his Twitter feed, he said that he wanted to focus more on regeneration issues in his Gloucester constituency and his other roles such as David Cameron's trade envoy.

His announcement came after David Burrowes said yesterday he was quitting as PPS to Environment Secretary Owen Paterson "in the best interests of my constituents and our party".
