JEREMY Corbyn sparked uproar last night after admitting a Government under his watch wouldn’t campaign for Northern Ireland to remain part of the UK.

Last night DUP MP Ian Paisley Jnr branded him a “destabilising” influence.

He said: “He clearly doesn’t care about the United Kingdom. If he did he would fight to keep it together”.

Mr Corbyn was asked by the BBC how a Corbyn government would handle a border poll campaign if it happened on his watch.

He said: “It’s within the terms of the Good Friday Agreement that such a poll could be held if there was a willingness to do so, at that point you don’t stand in its way, but it is within the terms of the Good Friday Agreement and I think the UK government should be neutral in that respect.”

It followed accusations he had snubbed the chance to meet families of IRA victims during the visit Belfast.

Challenged on why he hadn’t accepted an invitation he said he had only found out about it earlier in the week.

Mr Corbyn said instead his Shadow Northern Ireland secretary Tony Lloyd would be happy to meet victims’ groups.

But then he provoked more fury after calling for “ALL victims of all the violence” to be respected.

It came as one his own MPs branded him unfit for power because of his rejection of "mainstream" politics.

Ian Austin hit out at his party leader’s link to terrorist groups and response to anti-Semitism blasting his”extreme views” and accusing him of hijacking Labour.

Mr Austin, the MP for Dudley North, wrote on PoliticsHome: “The fact is that Labour has never in its history had a leadership as far to the left as this one. Never.”

“Jeremy’s supporters - for whom he can do no wrong - will dismiss this as the usual bitter smears to undermine him.

“But it is much more fundamental than that.

“The reason I didn’t support Jeremy’s candidacy and have not been persuaded since is because I just don’t think people with track records of extreme views like Jeremy Corbyn and John McDonnell should lead a mainstream party.”
