Last week Blair met senior politicians in Germany and Austria and Italy’s new interior minister, Matteo Salvini as well as the EU’s chief Brexit negotiator Michel Barnier.

Both have said they would be looking for Article 50 to be extended so a deal can be struck to remain in the EU that addresses concerns about immigration.

“The aim of the visits is to persuade EU leaders that British politics has made the option of remaining inside the EU viable,” said Mr Clegg.

“It is a question of pressing them to keep open the extension of the article 50 process beyond the March deadline to give UK negotiators more time including to prepare legislation on a people’s vote.

“We cannot just turn the clock back to just before the 2016 referendum.
