Camilla under new health precautions after tough week battling infection

She is attending a Booker Prize reception at Clarence House today.

However, a new health precaution has been taken as the Queen will meet guests for a shorter period than planned.

Camilla will also attend a Palace reception with King Charles on Wednesday.

The reception is to celebrate the TV and film industry, but she will not stay for the entirety of the engagement due to the new health precaution.

Queen Camilla will miss out on the star-studded Gladiator II premiere on Wednesday evening.

The changes to her diary are understood to have been made to protect and prioritise the Queen's continued recovery.

Royal doctors are keen to prevent any setback from the nasty chest infection.

On Saturday, a Buckingham Palace spokesperson confirmed Queen Camilla had pulled out of making public appearances at Remembrance services.

The Queen had been resting at home on doctors' orders since last Tuesday.

A Buckingham Palace spokesman said: "Following doctors’ guidance to ensure a full recovery from a seasonal chest infection, and to protect others from any potential risk, Her Majesty will not attend this weekend’s Remembrance events.
