Birmingham MP Gisela Stuart, pictured, has escaped disciplinary action over her campaign for a referendum on the European treaty.
A committee of senior MPs met yesterday to discuss what to do about four Labour backbenchers who have angered colleagues by calling for a referendum on the controversial Lisbon Treaty.
But no decision was taken on disciplinary action.
Ms Stuart (Lab Edgbaston), along with fellow Labour MPs Frank Field, Kate Hoey and Graham Stringer, argue that the treaty is effectively the same document as the European Constitution, which Labour pledged to hold a ballot on in its 2005 General Election manifesto.
They have upset colleagues by backing a publicity campaign targeting marginal seats including Redditch, where Jacqui Smith, the Home Secretary, will face a strong challenge from her Conservative opponent at the next election. The Birmingham Post understands they have agreed to remove their name from future press releases issued by the I Want a Referendum Campaign, although they continue to support the campaign in principle.
Ms Stuart is also expected to continue calling for a referendum in Commons debates.
Gordon Brown, the Prime Minister, came under fire yesterday during his Questions session in the Commons for allegedly threatening the MPs.
Ms Stuart has insisted she is supporting Labour Party policy by sticking by the manifesto commitment.
While some colleagues have accused her of helping the Conservatives with her campaign, she argues that Labour will win support from the public if it is seen to keep its promise to hold a referendum.
