BORIS Johnson has been booed once again by royal supporters as he attended the Queen's Jubilee concert. 

Social media footage showed the Tory chief making his way his seat in the royal box while being heavily booed by the crowds outside Buckingham Palace.

It comes after the Prime Minister and his wife Carrie were booed upon arrival at the Platinum Thanksgiving Service at St Paul’s Cathedral.

The incident followed Conservative donor named Michael Tory warning that Boris Johnson must be removed as PM “immediately” or the party will suffer “obliteration” at the next election.

The financier has given £340,000 to the party over the last 12 years – but now says he won’t give them any more cash until Johnson is ousted.

It comes amid reports that there may be a no-confidence vote this week as anger grows over the damning Sue Gray report, detailing the lockdown-breaching parties held across Downing Street and Whitehall.

The National:

Some 54 letters of no-confidence need to be sent to Sir Graham Brady (above), the chairman of the 1922 Committee, to trigger that vote. According to the Sunday Times, one Tory rebel estimates that as many at 67 letters have gone in during the secretive process.

If a vote does go ahead this week, 180 MPs would have to vote against him. If that threshold is not reached, Johnson is safe from leadership challenges for a year.

Meanwhile, one poll in the Sunday Times puts Labour 20 points of the Tories – and predicts a dismal result for Johnson in the upcoming Wakefield by-election.

Mr Tory said: “I was a loyal and longstanding donor but can only resume donating if there is an immediate change of leadership.

“And it has to be now — before it’s too late to avoid a richly deserved obliteration at the next election, followed probably by a decade in opposition.”

This week, Boris Johnson will seek to focus on efforts to tackle England’s NHS backlog built up during the pandemic as he looks to draw a line under the damaging row over the lockdown parties.

The Department of Health and Social Care signalled ministers will be making series of announcements in the coming week on the progress that the £12 billion-a-year catch-up programme is making.

In a statement, Johnson said: “The pandemic put unparalleled pressure on our NHS, but we are making excellent progress towards our goal of tackling the Covid backlogs.

“With record numbers of doctors and nurses, and a system backed by unprecedented government funding, we will continue to make sure patients receive world-class care whenever they need it.

“This week we will update on how we are driving down waiting lists and delivering more scans, checks and tests than ever before as we support the NHS in its biggest ever catch-up programme.”
