The UK Labour party is under pressure to ballot all party members on whether to begin campaigning for a second EU referendum, following elections to the European parliament.

Campaigners advocating for a ‘people’s vote’ wrote to the party’s national executive committee, saying in a letter that over 70% of Labour voters want a second referendum and to remain in the EU.

Labour leader Jeremy Corbyn says he will back a referendum on ‘any deal’ and will consult members about the best way forward, following a strong performance by the pro-remain Liberal Democrats and Greens in the EU elections.
