The King will host the first domestic state visit of his reign when he welcomes South African President Cyril Ramaphosa to the UK.
Charles will carry out his duties as head of state and salute the foreign leader at a ceremony attended by the Queen Consort and the Prince and Princess of Wales, and held at the Horse Guards Parade in Whitehall.
On the day that Mr Ramaphosa’s two-day state visit began, Prime Minister Rishi Sunak announced that the UK and South Africa would join forces to “together boost investment in infrastructure and Economic Growth “.
The next phase of the UK-South Africa infrastructure partnership kicks off on Tuesday, supporting South Africa’s economic growth through major infrastructure developments and providing increased access for UK businesses to projects worth up to £5.37billion over the next three years, Downing Street said. .
Mr Sunak said: “South Africa is already the UK’s largest trading partner on the continent, and we have ambitious plans to jointly drive infrastructure investment and economic growth.
“I look forward to welcoming President Ramaphosa to London this week to discuss how we can deepen the partnership between our two great nations and leverage shared opportunities, from trade and tourism to security and defence. “
The state visit will see a series of firsts for the Royal Family who will take part in events over the next two days welcoming their guest, Mr Ramaphosa.
Charles will preside over his first state banquet as a monarch, held in honor of the president, and will be joined by the Queen Consort, William and Kate due to be part of the Buckingham Palace event for the first time in their new roles.
South African High Commissioner Jeremiah Nyamane Mamabolo hailed the significance of the state visit after speaking to the King a few weeks ago when Charles visited a South African fashion exhibition in London.
Mr Mamabolo, who is expected to be among the guests at the state banquet, said: “The important thing is that the king has focused for his first visit on Africa, South Africa and the Commonwealth.”
During the ceremonial welcome on Horse Guards Parade, the President, accompanied by the King, will inspect the Honor Guard, found by Number 7 Company Coldstream Guards.
Afterwards, mall goers will be treated to the sight of a carriage procession carrying Mr Ramaphosa, the King and Queen Consort and William and Kate.
After a private lunch at Buckingham Palace, hosted by Charles, the King will accompany the President as he views South African items from the Royal Collection in the Picture Gallery.
