FIREFIGHTERS vowed yesterday to battle on against deadly Tory cuts to the service, while warning the beaten Blairites on the back benches it’s time to “wind their necks in.”

Fire Brigades Union (FBU) members from across Britain marched on Westminster to lobby MPs against the crippling 30 per cent cuts to the service brought in since 2010.

Budget cuts have already slashed 7,000 jobs.

Speaking to a fired-up crowd, the union’s leader Matt Wrack pounced on the Tories’ “senseless, dangerous agenda.”

And he told Labour leader Jeremy Corbyn’s critics to “shut up” as the lobby was attended by several senior Labour figures including shadow chancellor John McDonnell, Richard Burgon, Kate Hoey and Ian Lavery.

“Cuts undermine the ability of firefighters to do their job safety and effectively, people have died as a result — fact,” he said.

He also expressed concerns to a packed Commons briefing room over proposals that police and crime commissioners take control of fire and rescue services.

“Anyone who thinks firefighters’ neutrality will not be compromised by police commissioners is living in cloud cuckoo land,” he told members.

Mr Wrack also turned to the Parliamentary Labour Party, where Mr Burgon was shouted down this week.

After offering praise for Labour’s “unapologetic trade unionist” new leader, he said: “I don’t want to pry into the business of the Parliamentary Labour Party too much, but people may have seen the press reports of what went on in the PLP meeting this week.

“On behalf of the [FBU] executive council, and I hope on behalf of everyone, I would say those people who are trying to put the knife into Jeremy Corbyn and John McDonnell need to wind their necks in and shut up and abide by the democratic decision of Labour Party members, affiliated trade unionists and supporters and also in non-affiliated trade unions like us, like PCS, like the RMT.

“John and Jeremy have stood by those unions through thick and thin. We will now stand with them.”

Mr McDonnell, who chairs the union’s parliamentary group, thanked firefighters for their support and encouraged the union members to “keep lobbying MPs about dangerous cuts.”

Speculation has been growing that after Mr Corbyn’s victory that the FBU might be ready to reaffiliate to the Labour Party.
