Queen Camilla will no longer join the King at the Royal Variety Performance tonight.

Queen Camilla has pulled out of tonight’s Royal Variety Performance due to ‘lingering post-viral symptoms’ following her chest infection, Buckingham Palace has said.

A 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“With great regret, she has therefore withdrawn from attendance at tonight’s Royal Variety Performance.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.”

The Queen had returned to royal duties this week, joining the King and the Prince of Wales for the annual diplomatic reception on Tuesday night and attended events on Wednesday and Thursday.

But due to the length and lateness of the performance tonight, her doctors have advised that she stay at home to avoid overstretching herself.

It is understood that the Queen will remain in London tonight but will move to Sandringham for the week ahead, as was always planned.

This week medics had been closely monitoring her recovery from the nasty chest infection and were taking each engagement as they came.

But sadly today she is said to be feeling a little under the weather today and a royal source said that Camilla is “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 opes to be back to full strength and regular public duties very soon.”
