Camilla will attend a Booker Prize reception on Tuesday but will miss Gladiator II premiere the next day

The Queen will return to public duties today after her chest infection but will miss the Gladiator II premiere on Wednesday to aid her recovery, a royal source said.

Camilla missed the Festival of Remembrance at the Royal Albert Hall on Saturday, as well as Remembrance Sunday as she recovered from the illness.

On Tuesday, she will attend a Booker Prize reception at Clarence House but will meet guests for a shorter period than planned.

The changes to her diary are understood to have been made to protect and prioritise her continued recovery, with royal doctors keen to prevent any setback from a nasty seasonal illness.

Meanwhile, Harry Potter star Imelda Staunton and Duran Duran singer Simon Le Bon are among those set to receive royal honours at Windsor Castle.

Dame Imelda, who portrayed Dolores Umbridge in the fantasy series, as well as the late Queen Elizabeth II in Netflix drama The Crown, will receive her title for services to drama and charity on Tuesday.

Le Bon, whose hit songs include Rio and Hungry Like The Wolf, said he was “thrilled” to be made an MBE for his services to music and charity.
