JEREMY CORBYN’s deputy will launch a staggering all-out attack by claiming Labour must become a “proudly Remain party”.
In an astonishing breach of party policy, Tom Watson will say the opposition must be “loud and proud” in its support for Europe.
He will argue in a London speech that the Tory leadership contest highlights the risk of a No Deal – and that Labour must push for a second referendum, and to stay in the EU.
The defiant speech – coming before a Shadow Cabinet on Brexit - will incense Labour HQ but also swathes of MPs in heartlands across Yorkshire and North-East.
But Mr Watson will argue the best way to change the life of the poorest communities is to move forward “within” Europe.
And he will refer to a meeting with the Archbishop of Canterbury on interfaith dialogue where the Archbishop pressed the importance of politicians being able to “disagree well”.
Mr Watson will say: “Our members are remain.
'OUR VALUES ARE REMAIN'
“Our values are remain. Our hearts are remain.
“We must bring the public back into this decision and we must argue strongly to remain in Europe. Our future doesn’t need to be Brexit.
“We can change our future. But only if Labour makes the case for it – and we must.”
The incendiary move comes amid claims that as many as 130 constituency Labour parties (CLPs) have agreed to debate a motion at party conference that would force Jeremy Corbyn to “campaign energetically for a public vote and to remain”.
Insiders claim Mr Watson and Shadow Brexit Secretary Sir Keir Starmer have been quietly building a “party within a party” in Labour to force Mr Corbyn to come down for Remain.
The Labour leader conceded in the aftermath of the disastrous European elections that any Brexit deal would now “have to be put to a public vote”. But he has repeatedly called for a General Election over a second referendum.
Labour chairman Ian Lavery has warned the Shadow Cabinet that a second referendum could split the party in two.
