'Nazi song' sung by comic at dinner attended by Boris Johnson and Liz Truss

Boris Johnson and Liz Truss attended a dinner where a comedian joked that the Nazis should have won the Second World War.

Just days after both former PMs laid wreaths at the cenotaph during remembrance commemorations, they were guests of honour as comic Dominic Frisby sang: "We've lost our way, long past our best. So I suggest maybe we should have let the Nazis win.”

There was raucous laughter in the room as Mr Frisby went on: “They wouldn't have stood for the state that we're now in. The roads would be fine, the trains on time, we'd all have second language."

A Labour source said: "The public has already passed its judgement on two failed Tory Prime Ministers.

"Rather than conducting a dignified return to public life, Liz Truss and Boris Johnson seem determined to rub shoulders with wrong’uns. They should apologise and condemn this language immediately."

The source added: "It’s the same old Tories. They’ve learned nothing."

Nigel Farage, Tory leadership contender Robert Jenrick, business secretary Andrew Griffith and former Home Secretary James Cleverly also attended the bash to celebrate the 20th anniversary celebration of the Guido Fawkes website.

Suggesting further benefits of surrendering to the nazis, Mr Frisby sang: "No silly pronouns, unemployment down, we'd have Hugo Boss clothing and luggage."

After the song was over, he said: "For clarity, that was a joke" but admitted it was "probably a bit too close to the rubber".

Later, in a song poking fun at this Summer's riots, Mr Frisby sang: "You stand up for your people, if need be you would fight, but now if you uphold such values, then you are far-right".

The chorus, to the tune of Knees-Up Mother Brown, went "we're all far right now".

The next verse ran: "conduct doesn’t matter now, just your identity - and if you ever question this, you're racist obviously."

Another verse poked fun at people struggling with eating disorders and mental health issues.

"My son he is dyspraxic," he sang. “I’d presumed he was a d*ck. my mother is bipolar, my mate's got OCD, my girlfriend is bullimic, that gives me anxiety" - followed by a chorus of “we’re all mental now”, with Mr Frisby making a series of derogatory sounds which appeared to mock people with disabilities.

The song closed with Mr Frisby singing: “Oh my, what is coming next, we’re probably all paedos too.”

After this final song, he told the crowd of around 100 invited guests: “Well, you’ll never forget it. Perhaps I should have taken [Guido Fawkes Editor Paul Staines’] advice and not done the last one.”

Later in the evening Mr Staines, who has edited the gossip blog for two decades, revealed he was stepping down.

Playing the theme tune from Succession in the background, he announced he would become ‘Editor Emeritus’, and would be replaced as Publisher by Lord Kempsell, a former Guido Fawkes reporter who has more recently acted as Mr Johnson’s spokesman.

Also in attendance were former Tory leader Ian Duncan Smith, former Tory chairman Richard Holden, Shadow Defence Minister Mark Francois, Reform MPs Lee Anderson, Rupert Lowe and Richard Tice, former Chancellor Nadhim Zahawi and the semi-legendary Tory “fixer” Dougie Smith.

Mr Smith came to public attention recently after being accused of being behind a sinister plot to unseat Mr Johnson by Nadine Dorries, who was not present at the event.

Attendees enjoyed a three-course meal of smoked salmon, roast chicken and a date and honey flavoured dessert.

A spokesperson for Liz Truss declined to comment.
