Oat Corbyn there?

the economy. We have to realise the seriousness of the situation and the chaos in which our Government is operating.’

Mr Corbyn had a private meeting with the eU’s chief negotiator Michel Barnier and european Parliament president Antonio Tajani, who this week said a £20billion Brexit bill is ‘peanuts’.

Brexiteers accused Mr Corbyn of trying to interfere in negotiations, with former Ukip leader Nigel Farage saying it showed the eU was ‘playing divide and rule’.

Syed Kamall, the UK’s most senior Conservative MeP, said: ‘Jermey Corbyn coming here only helps the eU – he is effectively Michel Barnier’s puppet.

‘Barnier is very clever and he will use Corbyn, he’ll weaponise Corbyn.

‘he’ll use him for his own ends to help the eU side of the negotiations. One of the negotiating tactics is the ability to be able to walk away from a deal.’ At a europe Together conference attended by socialist leaders he was mobbed by supporters and received two standing ovations.

he was introduced by Gianni Pittella, leader of the european Parliament’s socialist group, as ‘the new prime minister of Britain’.

Mr Corbyn used the event to poke fun at Chancellor Philip hammond’s recent reference to the eU as ‘the enemy’.

‘Let me be clear, the British Labour Party does not see anyone in europe as an enemy,’ the Labour leader said.

‘We see people across europe as friends. You are our colleagues, our partners, our comrades and our friends.’

he also used the speech to call for the return to socialist governments across europe, claiming that low taxes and inequality were benefiting the rich.
