Kate Middleton, the Queen and Camilla have paid a visit to luxury department store Fortnum and Mason where they have been given a tour of its famous food hall, before enjoying a tea party and inspecting cakes at the 300-year-old emporium.
Kate wore a yellow daffodil on her coat for St David's day, while the Queen wore a sky blue coat and hat, similar to the trademark turquoise of the department store itself. The royal trio seemed to have colour coordinated for the outing, with Camilla dressed in a navy blue coat with eye-catching white horizontal stripes at the top.
Crowds holding placards and cheering lined the streets of Piccadilly to greet the royal party. However a small group of protesters also were present, campaigning against the store's sale of Foie Gras.
The Royal Family's leading ladies, who are related by marriage only, will meet military personnel involved in the Gifts For Troops scheme, which sends packages to soldiers serving in Afghanistan.
It is the first joint royal outing for the Queen, the Duchess of Cambridge and the Duchess of Cornwall, who will also be treated to a display of tea and biscuits similar to those which will be sent to troops deployed overseas on operations during the Diamond Jubilee weekend.
The Queen will meet recipients of grants from the Queen Elizabeth Scholarship Trust (Qest) - the charitable arm of the Royal Warrant Holders Association.
Qest makes awards ranging up to £15,000 to craftsmen and women of all ages to help them further their careers.
Later, a tea party will be held at the store for the three generations of royals. Around 150 staff, suppliers and former employees, will enjoy a traditional British brew with the women. Some of the staff present will have worked at Fortnums and Masons since the time of the Queen's Coronation.
The royal visitors will then inspect a cake to commemorate the renaming of the restaurant to The Diamond Jubilee Tea Station before the Queen unveils a plaque to commemorate the regeneration of the Piccadilly area.
