LABOUR is preparing for a "good kicking" from voters as the European Parliament elections count looms, John McDonnell has said.

The party's shadow chancellor says it will "probably" suffer a humiliating result as support crumbles over its handling of Brexit.

Jeremy Corbyn's team has faced repeated criticism for its lack of clarity over EU withdrawal.

Writing in The Observer, Labour's deputy leader Tom Watson called on the party to "find some backbone" and fully commit to a second Brexit referendum in order to have a chance of success in the next general election.

Speaking on Sky's Ridge on Sunday show, McDonnell said he understands the frustrations of Labour's Remain supporters.

However, he said his party had been right to "tread a really difficult road" of trying to bring Leave and Remain supporters back together.

McDonnell said: "I think we most probably will get a good kicking in the election results tonight.

"We'll see. We are braced for that."

"But, you know, we had to do the responsible thing.

"It was a hard road to follow. But someone had to be there and say 'Can we bring the country back together again?'

"And it would have been easy to go to one side, go to the Remain side and ignored all those people who voted Leave. That's not the nature of our party. We are the party that is trying to bring people back together again.

"That's been difficult electorally for us in these elections, of course it has. But now we have got to move on."

Watson said he feared the results of the European elections would show voters had deserted the party and blamed Labour's ambiguous position on a public vote, stating that its performance at the polls "is a direct result of our mealy-mouthed backing for a public vote on Brexit when it is being demanded loud and clear by the overwhelming majority of our members and voters".

He went on: "Polls show Labour has been losing up to four times more voters to parties giving full backing to a people's vote than to Farage.

"And those same polls show we would have beaten him by a country mile if we had unambiguously backed a public vote on any form of Brexit.

"Once results are in, we must channel our frustration into winning those voters back. Never again can Labour policy on the most crucial issue of our generation be on the wrong side of its members and voters."

Watson described the party's stance on a second referendum as "a deliberate, self-defeating attempt to triangulate between different groups".

Ahead of the European elections, Jeremy Corbyn saw off an attempt by pro-EU members to commit the party to a confirmatory referendum on any Brexit deal.

The party's ruling National Executive Committee agreed that its manifesto would instead stick to the wording of a motion passed by Labour conference last year, which keeps a public vote on the table as a last option.

This decision was made by a "small number of people" and should instead be made by party members, Watson said.

The deputy leader also vowed to support calls for Labour's Brexit policy to be changed before the autumn party conference.

"I fear that unless our policy on Brexit changes we will not have the opportunity to be the radical reforming government that so many millions of people in our country need," he said.

"The campaign to change that begins now."
