"demolishes another of the Leave campaign's fantastical claims - that Brexit would have no impact on the Irish border"

“As each day goes by, it becomes clearer that the best deal for everyone is to stay in Europe. The people of the UK must be given a vote on the deal and an opportunity to exit from Brexit.”

“For the government to threaten to leave the EU with no deal, while boasting about not having a plan for that eventuality, is completely unacceptable.”

“The public will never forgive Labour if the frontbench lose their bottle on Brexit. The Liberal Democrats can guarantee we will fight for the people to have a final say on Brexit, including the option to remain, at every opportunity.”

“This is yet another top Brexiteer leaving a sinking ship. It speaks volumes that UKIP's first elected MP is throwing his weight behind Theresa May, who has adopted UKIP's hard Brexit agenda to the letter.”

“Boris was bang on about the threat of Brexit to the economy and the unity of the country - it is a shame he did not listen to his own warning.”

“People should be able to judge Boris Johnson on his actions not his words, with the chance to reject a disastrous Brexit deal and stay in the EU.”
