Nusrat Ghani, Conservative MP for Wealden, laughed as she suggested Tim Farron's party would simply hold "a number of referendums" until they are happy with the terms of Britain's European Union divorce.
Lib Dem peers will continue their party's push for a second EU referendum in Parliament's upper house, after MPs suffered defeat in the House of Commons over their bid for a national vote on the final Brexit deal agreed by Theresa May's Government.
"The two amendments they spoke about, one about EU citizens – assurances have been given by the Prime Minister that these issues will be prioritised in negotiating the best deal possible."
Nusrat Ghani mocked the Lib Dems for attempting to delay Brexit negotiations
They would like to negotiate for as long as it takes to get best deal possible
Commenting on the possibility of the deal being done in the two-year Article 50 period, the Tory MP quipped: "You also heard from the Liberal leader [of the House of Lords] Lord Newby that they would like to negotiate for as long as it takes to get best deal possible.
"And then have a number of referendums, until the Liberal Democrats are happy with whatever outcome they think best suits the country."
After failing in the Commons, Mr Farron will hope his party's greater clout in the House of Lords will give them a better chance of securing their amendments to the Article 50 Bill.
There are 102 Liberal Democrat peers and 203 Labour peers in the upper house, where the Tory Government does not hold a majority in contrast to the Commons.

Responding to claims of a Lib Dem plot to put a brake on Mrs May's Brexit negotiations, the Liberal Democrat leader in the upper chamber Lord Newby said: "I understand that view, but as I said, we are not holding it up.
"There's a big distinction between amending the bill, under a normal timetable, and holding it up. We're going to be amending it.
"Frankly, if the House of Lords cannot ask the Commons to think again, it might as well pack up its bags and go home."
Ms Ghani said: "The country has decided, we have had extensive debates in the House of Commons, and it has passed with an overwhelming majority to enable us to trigger Article 50 and begin these negotiations."

GREAT YARMOUTH: The town of Great Yarmouth on the East Coast of England voted by 72% to leave the European Union.
The Prime Minister issued a direct warning to the upper chamber's members, demanding they don't delay her attempts to trigger Article 50 by the end of next month.
Speaking during a visit to Stoke before the by-election, Mrs May said: "[The bill] was not amended [in the House of Commons].
"I hope that the House of Lords will pay attention to that. Properly there will be debate and scrutiny in the House of Lords, but I don't want to see anybody holding up what the British people want, what the people of Stoke-on-Trent voted for last year, which is for us to deliver Brexit, to leave the European Union."
