The Government has ruled out giving MPs a vote on Brexit, saying to "second guess" the British people would be unacceptable.
A spokesperson for Prime Minister Theresa May said while it was "absolutely necessary" for the MPs to scrutinise the "process" of leaving the EU, MPs should not be given a vote.
He said: "Parliament is of course going to debate and scrutinise that process as it goes on. That is absolutely necessary and the right thing to do.
"But, having a second vote, or a vote to second-guess the will of the British people is not an acceptable way forward."
The announcement comes after former Labour leader Ed Miliband joined forces with key Conservative and Lib Dem politicians to try and persaude Prime Minister Theresa May to hold a vote in Parliament on leaving the European Single Market.
Article 50 - the process which begins Brexit - will be triggered by the end of March 2017, the Prime Minister announced last week.
