Jeremy Corbyn will next month face pressure from union leaders to back a second referendum on Brexit, The Telegraph can disclose.

Two motions to be debated at the TUC annual congress in Manchester call for unions to campaign for a second referendum on Britain’s exit from the European Union.

It came as Andy Burnham, the Labour Mayor of Manchester, suggested that those campaigning for a second referendum on Brexit are "arrogant" and warned that it risks "inflaming" resentment.

Labour is split over a second vote with Sir Keir Starmer, the shadow Brexit secretary, last week refusing to rule one out, and Barry Gardiner, another frontbencher, saying it would risk civil disobedience.

In an interview with the Politico website, Mr Burnham said: "My frustration with those leaping to a second referendum is it further inflames this idea of an arrogant political class, which isn't listening and isn't dealing with the issues that gave rise to the referendum in the first place.
