The result of the ballot of the party’s membership will be announced at around 4pm on Monday.

The party has 12 MPs – bolstered by Chuka Umunna’s decision to join last month – and came second in the European elections, winning 20% of the vote share.

The Lib Dems also enjoyed a surge at the local elections in response to their anti-Brexit stance.

Ms Swinson has suggested that if Boris Johnson enters Number 10 and is committed to Brexit on October 31 with or without a deal then the Lib Dems could be boosted even further.

Sir Ed has previously suggested that a government of national unity led by a Labour backbencher could be a way of stopping a prime minister intent on a no-deal Brexit.
