The European Union could help Britain hold a second Brexit referendum by allowing it to nominate Members of the European Parliament for a very short period, Luxembourg's Foreign Minister Jean Asselborn has said.

Mr Asselborn told Reuters that any second referendum was likely to push the timetable back by six months or more, and the European Parliament's elections in May were a problem but did not need to be a stumbling block.

The UK is scheduled to leave the EU on 29 March and so far there is no agreement on the Withdrawal Agreement.

Meanwhile, former Ukip leader Nigel Farage said he would neither campaign nor vote in a second referendum if the choice was between Theresa May's deal - which he denounced as "Brexit in name only" - or Remain.

Mr Farage told Sky News's All-Out Politics: "Honestly, if we are offered Brexit in name only or Remain, why on Earth would I vote? I would go on holiday. It would be an outrage.

"Remain shouldn't even be on the ballot paper, but if we are forced to this, it would have to be Remain or a clean Brexit."

Mr Farage said if the choice was Mrs May's deal or Remain, "I wouldn't campaign and I wouldn't vote because it wouldn't offer me Brexit".

He suggested that a second referendum result would be invalid if significant numbers of Leave supporters followed his lead and refused to take part.

"You have to have a certain level of turnout for any referendum to be valid," he said.
