ONE of Boris Johnson’s headline boasts from his recent trip to the US has been rubbished by his own government.

A Downing Street official labelled as “misleading” the Prime Minister’s claim that the US is lifting a historic ban on British lamb imports, including kebabs and koftas.

Emails, seen by the Daily Record, show that it is “extremely unlikely” the restrictions on those products would actually be scrapped.

The SNP say Johnson has been “skewered by his own dishonesty”, while Labour said he’d been “left looking sheepish”.

During his pan-Atlantic trip, the Tory leader vowed to end a ban on lamb exports which has been in place since the original outbreak of mad cow disease in 1989.

He announced on September 22: “I can tell you today that what we’re going to get from the US now is a lifting of the decades-old ban – totally unjustified, discriminating against British farmers – the ban on British lamb. We are going to be able to export British lamb to the US for the first time in decades.

“It will be for the kebabs, the koftas, the lamb burgers … the people of the US will be supplied at last by Britain.”

Yet leaked emails from the UK’s Department for the Environment, Food and Rural Affairs (Defra) contradict those claims.

Sent the day after the PM’s boast, the message from a Defra official states that “some of what he said was misleading”.

It sets out policy guidelines for government worker which clarify the true likelihood of the ban being scrapped.

The email reads: “To clarify, we understand that the ban has not yet been lifted, but we do expect a final review of the rule (which will recommend the ban should be lifted) to be published within the next week. This said, there would still be many steps to be taken before exports can comments [sic].”

It adds: “Kebabs, koftas – as named by the PM – are extremely unlikely to be initially eligible for exports due to specific requirements for such products.”

The revelations are highly embarrassing for Johnson’s administration and prompted a wave of criticism from political opponents.

SNP MSP and former sheep farmer Jim Fairlie told the Record: “Boris Johnson has been skewered by his own dishonesty. These are damning revelations from inside the UK Government which appear to show the Prime Minister has blatantly tried to mislead people.”

Labour’s shadow scottish secretary Ian Murray added: “Once again, Boris Johnson has been skewered by the truth. There was no substance to his promises and he’s been left looking sheepish.”

Defra stated that it does not comment “on leaked documents”.
