David Lammy was branded a "Remaniac" after he denied Britain's lower tariff by Donald Trump was a Brexit benefit. The US President last week unveiled sweeping taxes on goods entering the US from countries around the world.

The UK faces a 10% tariff, which is lower than the European Union which was slapped with 20%. But Foreign Secretary Mr Lammy, an arch-Remainer, insisted the lesser rate was "nothing to do with Brexit".

He told Politico: “We are facing a significant change in the way the global trading system works, but it has nothing to do with Brexit.

“We have been working intensively in recent weeks on a negotiation for a broader economic agreement with the United States, and these negotiations will continue.”

Reform UK deputy leader Richard Tice hit out at Mr Lammy over his comments.

The Brexiteer told GB News: "No matter how much Remainiac Lammy tries to hide it, the truth is that we have avoided 20% tariffs as a direct result of Brexit.

"Instead of re-litigating arguments of the past, this Labour Government should be focused on doing Brexit properly, getting rid of EU regulation and making us the most pro-business country in Europe - something Kemi failed to do in her time as Business Secretary."

Mr Lammy's comments are at odds with other Labour MPs who have admitted the 10% rate is a Brexit win.

Chief Secretary to the Treasury Darren Jones yesterday acknowledged it was a "Brexit dividend".

He told Sky News: "It is, there's one. I've struggled to find one in the past but there is one we've ended up with."
