Over 3,000 members of Momentum are part of group plotting ways to smear Boris Johnson’s partner Carrie Symonds

MORE than three thousand hard-left members of Jeremy Corbyn's Momentum campaign are part of a private messaging group that discusses how best to smear Boris Johnson's partner, the Chief Rabbi and individual Tory candidates, it emerged last night.

The group - set up by staff of Momentum and involving activists working directly with Mr Corbyn's team and Labour HQ - have also used the secret forum to discuss strategy on how best to inflame tensions among ethnic minorities.

And the dossier leaked last night also reveals how the leftie mob plotted to politicise major events such as the London Bridge attack.

They produced a 13-page dossier titled "Tory cuts let attacker free to kill" in order to ensure they used the horrifying terror attack to damage the Tory election campaign.

The group also dug for dirt on the Prime Minister’s girlfriend Carrie Symonds through researching her ex-partners.

The group was marshalled by Momentum staff who had been working to “dig up dirt” on opposition candidates – despite Mr Corbyn’s “when they go low we go high” claim at the start of the campaign.

Some of the research has even been endorsed by Jeremy Corbyn, who personally gave the green light for some of it, according to leaked documents.

The shocking dossier came as Justice Secretary Robert Buckland accused Labour of organising a hate mob to attack Health Secretary Matt Hancock when he tried to visit the Leeds hospital where a four-year-old boy was left sleeping on the floor.

Mr Hancock was viciously abused by Corbyn supporters, one of whom shouted: “You are not welcome in this country.”

Mr Buckland told the Today programme yesterday: "They clearly organised themselves to come along, create trouble and mischief, the sort of disorderly conduct I'm afraid from the left that we've seen in this campaign.

"People who had clearly organised themselves to come along, create trouble and mischief, the sort of disorderly conduct I'm afraid from the left that we've seen in this campaign. It's not a way to conduct civilised politics, people were shouting and gesticulating towards Matt Hancock and his team."
