JEREMY Hunt has lashed out at Boris Johnson over the Brexit customs row, as it also emerged last night that that the Cabinet impasse will last for weeks.

Inflaming raging tensions yet further, the Health Secretary told the Foreign Secretary to shut up about the spat in public.

Boris infuriated No10 by branding Theresa May’s preferred plan which would see Britain collect the EU’s trade tariffs as “crazy”.

Siding with the PM, Mr Hunt told Radio 4’s Today Programme: “I do think that it is important that we have these debates in private because this is a negotiation and so on the EU side if they see divisions in the open then they will exploit that.

“We should have these debates in private because that will strengthen Theresa May’s negotiation.”

But Mr Hunt refused to join pro-EU Tories in calling for Boris to resign, adding: “I would say he’s a marvellous Foreign Secretary, but let’s work as a team”.

Downing Street sources last night revealed it would be “a couple of weeks” before a firm decision is made on which of two customs options the government will opt for.

The Cabinet’s deeply divided 11-strong Brexit committee meets today in what was expected to be a showdown to hammer out their differences between the Customs Partnership plan and the alternative ‘Maximum Facilitation’, which will see trade hold ups eased by technology.

But instead, the two working groups studying the two options will only now give their preliminary reports.

Worried Theresa May took the unprecedented step of calling in all backbench Tory MPs to No10 to discuss the two customs options yesterday.

The invitation to attend five different briefing sessions – headed up by Mrs May – was made to try to quell growing rebellions from Troy Remainer and Brexiteer wings.

The PM won support from Brexiteers’ leader Jacob Rees-Mogg, who branded her “the Geoffrey Boycott of negotiations”.

The senior Tory backbencher said: “She is playing a straight bat, she isn’t giving a great deal away – I probably know as much about her approach as anybody else does”.

The fresh Cabinet delay comes as the EU’s chief negotiator Michel Barnier yesterday declared there has been “no significant progress” on Brexit since March.

An exit deal must be agreed by October, leaving just five months left.

Germany’s Europe Minister Michael Roth warned in Brussels: “As we have been for some time we are concerned that we don’t have clear positions from the British side. Time is running on and we need to make substantial progress.
