Brexit Party MEPS booed a woman nominated to be president of the EU Commission after she said the UK’s exit from the bloc could be delayed again beyond October 31.
Ursula von der Leyen clashed with the party’s leader Nigel Farage in the European Parliament as she insisted she would allow another Brexit extension if there were good reasons.
The German politician told MEPs in Strasbourg she respected but regretted the UK’s decision to leave the EU.
She said: “We cannot talk about Europe without talking about our friends from the UK.
“For the very first time, in 2016 a member state decided to leave the EU. This is a serious decision, we regret it but we respect it.
“Since then, together with the current government of the UK, the EU has worked hard to organise the orderly departure of the UK.”
The Withdrawal Agreement negotiated with Theresa May’s administration by Michel Barnier “provides certainty where Brexit created uncertainty”, she added.
“However, I stand ready for a further extension of the withdrawal date should more time be required for a good reason.”
Mr Farage said the remarks from the Commission hopeful would have made Brexit “more popular” in the UK.
He said the European Parliament had been “humbled and humiliated” by the process which led to Ms von der Leyen’s nomination by the European Council.
And he claimed that she was leading an attempt for the EU to become a “centralised, undemocratic, updated form of communism” and suggested she was a “fanatic for building a European army”.
He added: “In some ways I’m really rather pleased because you have just made Brexit a lot more popular in the UK, thank God we are leaving.”
Ms von der Leyen, the German defence minister, shot back, saying it was important to continue to work with the British “but I think, Mr Farage, we can probably do without what you have got to say here”.
Tory leadership frontrunner Boris Johnson has insisted he will not shift from the October 31 deadline but his rival Jeremy Hunt has indicated he would be flexible if a deal was within reach.
MEPs will vote on whether to back Ms von der Leyen to replace Jean-Claude Juncker at the head of the European Commission later on Tuesday.
