The Queen has insisted the “show must go on” after pulling out of the 2024 Royal Variety Performance because of lingering symptoms from a chest infection.

Camilla had been due to join the King at the event on Friday night which is taking place at London’s Royal Albert Hall and will feature performances from stars including Sir Elton John and Sophie Ellis-Bextor.

The Queen has appeared at several events after falling ill with the infection earlier this month but doctors have advised her that she should prioritise rest.

A Buckingham Palace spokesperson said: “Following a recent chest infection, the Queen continues to experience some lingering post-viral symptoms, as a result of which doctors have advised that, after a busy week of engagements, Her Majesty should prioritise sufficient rest.

“With great regret, she has therefore withdrawn from attendance at tonight’s Royal Variety Performance. His Majesty will attend as planned.”

A Royal source said the Queen was “naturally disappointed to miss the evening’s entertainments, and sends her sincere apologies to all those involved, but is a great believer that ‘the show must go on’.

“She hopes to be back to full strength and regular public duties very soon.”

It is understood Camilla will remain in London on Friday and will then travel to Sandringham for the following week as planned.

Earlier this week, the Queen was praised for her “exceptional efforts” to advance literature as she received an honorary doctorate from her sister-in-law the Princess Royal.

Camilla donned ceremonial robes as she was recognised for her long-standing promotion of literacy and literature during a ceremony at the University of London on Wednesday, where Anne has been chancellor since 1981.

On Tuesday night, Camilla – who recently suffered the death of her beloved Jack Russell terrier, Beth – hosted a glittering white-tie diplomatic reception alongside Charles at the Palace.

She also attended a Booker Prize reception with shortlisted authors at Clarence House last week before joining the King at a special reception at Buckingham Palace celebrating the TV and film industry, although she pulled out of the royal premiere of Gladiator II on the same night.
