Prime Minister Theresa May is under fire after it emerged she has previously said MPs should have the right to veto any negotiations between the UK and EU.
Mrs May is reported to have said back in 2007 that ministers should have to get Parliamentary approval before any talks with the EU.
However, despite those earlier claims, she is now refusing to give MPs a vote on Brexit plans.
Downing Street has said her comments nine years ago were unrelated to the current situation and related to how policy was negotiated while Britain was inside the EU.
In June, however, UK voters decided to leave the EU, and Mrs May says she respects the democratic process and is pushing forward with Brexit.
A leaflet which was published in 2007 reveals that Mrs May, then a Conservative MP in opposition to the Labour government, said ministers should have to set out their negotiating positions and gain approval from a Commons committee before discussions take place with the EU. She goes as far as to say that ministers who fail to do this should resign.
Mrs May has said that MPs are “very likely” to be given a say on a final Brexit agreement once it is reached between the UK and the EU.
However Remain campaigners say that Mrs May should go further by giving a vote on what the government’s negotiating strategy will be. That is a suggestion which has been firmly rejected by Mrs May’s camp who say she will not want to give away her tactics before entering into discussions.
Former shadow minister for Europe, the Labour MP Pat McFadden has said Mrs May must realise she needs to give MPs a meaningful role in how negotiations are carried out and what Brexit means.
He said: “This paper shows that the prime minister does in fact believe that ministers should get parliamentary approval for negotiating strategies with Europe.
“Sooner or later, ministers will realise that they can’t support Brexit in the name of parliamentary sovereignty and deny parliament a meaningful role in what Brexit means.”
Mrs May has already promised to trigger Article 50 of the Lisbon Treaty, which will signal two years of exit negotiations with the EU, by the end of March next year.
However, she will not be giving a vote to MPs before Article 50 is triggered and says those who are demanding a say before then are simply trying to subvert the result of the referendum in June.
