Nick Clegg has told his Liberal Democrat MPs to abstain from the vote, many of whom are angry with the speed at which David Cameron supported the Culture Secretary, after he told the Leveson inquiry into press standards that he acted impartially.

These demands have been public for several weeks now, since Mr Hunt’s conduct over News Corporation’s bid to buy out BSkyB, and his impartiality when deciding the outcome. Critics said that Hunt did not act with true impartiality before the bid was cancelled in the wake of the phone hacking scandal.

Emails sent before he was given the job suggest Mr Hunt was supportive of the Murdochs’ bid, as well as the closeness his “special advisor” Adam Smith allegedly had with News Corps lobbyists.

Smith has since resigned, but many claim Hunt has not taken full responsibility over it.

The investigation that Labour are calling for is set to look into whether Mr Hunt broke the ministerial code by not giving "accurate and truthful information to Parliament" over his contacts with News Corp during the bid process.

Conservative housing minister Grant Shapps told BBC Radio 4 this morning,  "It's a reminder that this is two parties who came together in the national interest to sort out these huge debt problems... it's a reminder that we have a different perspective on things."

Even if all 57 Lib Dem MPs abstain, the vote is still expected to go the government’s way.
