Responding to comments from Andrea Leadsom on the Marr show, Liberal Democrat spokesperson Tom Brake said:
"What we saw this morning from Andrea Leadsom was shocking intransigence.
"There is absolutely no clarity on what sort of deal the government is seeking with Labour and no real plan to move forward.
"The country will never accept backroom deals done at the 11th hour to push through Brexit.
"It is time for the Conservatives to compromise and by giving the people the final say in a vote on their deal with an option to stay in the EU."
