“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 prioritize sufficient rest," the statement read.

Britain's Queen Camilla has pulled out of an event on Friday night as she continues to experience some symptoms of illness after suffering a chest infection earlier this month, a Buckingham Palace spokesperson said.

Queen Camilla has pulled out of another public appearance after missing the Royal Variety Performance - and a doctor has now shed some light on her condition.
