King Charles hailed the work of the Commonwealth in bringing countries together as he and Britain's senior royals gathered at London's Westminster Abbey on Monday for annual celebrations for the international organisation he leads.

Multiple members of the Royal Family are set to gather in London today for the annual Commonwealth Day Service. The event will take place at Westminster Abbey and will focus on the theme ‘Together We Thrive’, which celebrates the spirit of the Commonwealth.

At the time, Kensington Palace stated that Princess Kate was not expected to return to public duties "until after Easter," which fell on March 30. However, on March 22, she appeared in a video message, sharing that she had been undergoing chemotherapy for an undisclosed form of cancer following post-operative testing.
