Theresa May has warned that a second referendum would "shatter" faith in democracy and damage "social cohesion" as she set out her "Plan B" for Brexit.

Refusing to budge on her red lines, the Prime Minister said she had listened to the concerns of MPs but would not give in to calls for a customs union, a second vote or for her to rule out no deal.

Setting out the Government's action plan following the historic defeat in the Commons last week, Mrs May hit out at Jeremy Corbyn for refusing to engage in talks.

Whilst he has insisted that cross-party discussions are conditional on her taking no deal "off the table", Mrs May said that the only way to do that would be to revoke Article 50, a move that would kill-off Brexit altogether.

Addressing those who have called for an extension of Article 50, Mrs May said that doing so would only "delay" the need to make a decision on Brexit, adding that it would still not rule out no deal.

And while some MPs believe that a second referendum is the only way to break the Parliamentary deadlock, Mrs May said that she did not believe there was a majority in the Commons for it.
