Mandelson: I regret we were not more successful in countering that ridiculous, fantasy politics and propaganda that spewed out of the Leave campaign.

I feel that we could and should have done so much more, particularly as the Labour party, to sort of join up the dots for people, to explain what the consequences would be, what the negative impact would be on jobs and pay packets in the North East in so far as we didn't do that well enough, we politically in the Labour party have to take responsibility for that.

I also think people in the North East were sold this ridiculous notion that coming out of the European Union was some sort of 'magic bullet' to solve all our country's problems with immigration. You should've looked really at the small print of what the Leave people were saying.

They didn't have one shred of an idea, not one single policy that explained how immigration would be changed if we came out of the European Union, but with such single-mindedness they whipped up people's emotions, they led people to believe that all this could be transformed overnight, that we could stop Turkey coming into the European Union - Turkey isn't going to come into the European Union while you and I are alive - that our population was going to explode if we stayed in the European Union.

I really regret we were not more successful in countering that ridiculous, fantasy politics and propaganda that spewed out of the Leave campaign.
