The Emir of Qatar will begin a two-day state visit to the UK hosted by the King.
Charles will welcome Sheikh Tamim bin Hamad Al Thani and the first of his three wives, Sheikha Jawaher, during a ceremony of pomp and pageantry staged in Whitehall.
But missing will be Queen Camilla who, on Monday evening, pulled out of the official open-air greeting on Horse Guards Parade and a carriage ride back to Buckingham Palace, due to lingering effects of a recent viral chest infection.
Camilla will join the royal party later for a private lunch with the Emir and his wife and will also take part in all but one of the elements of the evening state banquet at Buckingham Palace, staged in honour of the Emir.
The Prince and Princess of Wales will take part in the ceremony on Horse Guards Parade, one of the few official appearances by Kate during a year in which she has been successfully treated for cancer.
The princess has been gradually returning to royal duties after she announced in September she had completed her chemotherapy treatment and her focus was “doing what I can to stay cancer free”.
She will travel with her husband in the carriage procession and the couple will join Charles and Camilla as they host a lunch for their guests Sheikh Tamim and Sheikha Jawaher.
However, Kate will not attend the state banquet hosted by the King, although William will be a guest.
Doctors have urged Camilla, 77, to take time to rest and recover fully because of the lingering effects of the illness, contracted a month ago following her long-haul trip to Australia and Samoa, which include diminished reserves of energy.
She is hoping to be able to view a display of Qatari artefacts after lunch in the palace’s picture gallery with her husband, the Waleses and the Emir, and at the start of the state banquet will pose for a group photo but will take a short break before dinner while guests are met in a receiving line.
No major changes are expected to her diary for the rest of the week, but the Queen has been advised by her medical team to take each day as it comes.
Meanwhile, the occasion marks the start of a busier week for Kate, who will be hosting her annual Christmas carol service at Westminster Abbey on Friday, when she is expected to be joined by her children and husband for the event.
Sheikh Tamim, 44, was educated in Britain, attending public schools Sherborne and Harrow, before graduating from Sandhurst military academy.
On Wednesday, the final day of the two-day visit, the Emir will visit Sandhurst before travelling to the Palace to bid farewell formally to the King and Queen, with Camilla expected to be there.
Sheikh Tamim will also travel to Downing Street for bilateral talks with Prime Minister Sir Keir Starmer.
Qatar, one of the richest Gulf states, is a key mediator in the Israel-Hamas war, and there are reports the Government is hoping to seal a free-trade deal with the Gulf Co-operation Council.
But the country has faced criticism over its human rights record, in particular the abuse of migrant workers during Fifa World Cup in 2022, its criminalisation of same-sex relationships, and its discrimination against women.
Human rights campaigner Peter Tatchell condemned the decision to “reward” the Emir with the honour of a state visit, saying “Feting the Emir is collusion with tyranny”.
His Peter Tatchell Foundation is to stage a peaceful protest near Buckingham Palace, at Canada Gate to the right of the royal residence, on Tuesday morning ready for when Sheikh Tamim arrives in the carriage procession.

Mr Tatchell said: “Keir Starmer and King Charles should not reward the Emir with the honour of a state visit while his regime continues to victimise women, LGBTs and migrant workers.
“Feting the Emir is collusion with tyranny.”
He added: “The Qatar government is a police state dictatorship. It’s guilty of systemic homophobia, sexism and the suppression of workers’ rights and basic freedoms like free speech and the right to protest.
“This state visit sends the wrong message – that the UK prioritises trade and investment over human rights.
“The UK should be challenging Qatar’s human rights record and seeking the release of political prisoners, not rewarding its ruler with royal pageantry and red carpets.”
Mr Tatchell travelled to Qatar to stage an LGBT+ rights protest during the Fifa World Cup, but told how he was detained and interrogated by the authorities before being ordered to the airport to depart the country.
“This London protest is about continuing to expose the brutal reality behind Qatar’s carefully crafted public image,” he said.
He added: “We urge everyone who values equality and freedom to join our peaceful protest.”
