Britain could rejoin the EU if voters wanted to withdraw Article 50 after the general election, the president of the European Parliament has said.

“If the UK wanted to stay, everybody would be in favour," Antonio Tajani told The Guardian after a meeting with Theresa May at Downing Street to discuss Britain’s withdrawal from the EU.

The veteran Italian politician's comments appeared to contradict the prime minister, who has repeatedly said there can be “no turning back” now that Article 50 has been triggered.

Labour has also ruled out a second referendum on EU membership if they are elected on 8 June.

A spokesperson for party leader Jeremy Corbyn said it was "not our policy and it won’t be in our manifesto”.

But Mr Tajani said:“If tomorrow, the new UK government decides to change its position, it is possible to do. The final decision is for the 27 member states, but everybody will be in favour if the UK (decides to reverse article 50).”

Vowing to protect EU citizens in the UK, he added that he was prepared to veto a deal that did not guarantee their current treaty rights.

“It’s important to ensure that Brexit does not have negative effects on [EU Citizens’] lives, and rights they are enjoying," he said. "For us, it’s a priority and a red line.”

In draft negotiating guidelines leaked earlier this week, the EU said the European Court of Justice would rule on the terms of its citzens’ rights after Brexit.

This would mean any future British government could not change the terms of the agreement.

Mr Tajani said his meeting with Ms May had been "positive".
