The Labour Party will tomorrow call on all parties to back a motion in the House of Commons to stop MPs holding paid directorships or consultancies.

The vote comes as David Cameron rejected Ed Miliband’s call for him to follow Labour’s lead in banning MPs from holding paid directorships and consultancies, and the day after Malcolm Rifkind decided not to stand again as a Conservative MP.

A Labour Party Spokesperson said:

“We need to act to improve the reputation of our political system in the eyes of the British people.

“MPs are dedicated to the service of their constituents and the overwhelming majority follow the rules. But the British people need to know that when they vote they are electing someone who will represent them directly, and not be swayed by what they may owe to the interests of others.

“Labour MPs and Prospective Parliamentary Candidates have already been put on notice that from the coming General Election the Party’s Standing Orders will be changed to prevent them holding such second jobs.

“David Cameron once promised change but now defends a discredited status quo and has refused to follow Ed Miliband’s lead. This is his chance to vote for an important measure which would help restore trust in politics.”
