The Duchess of Cambridge continues to establish herself as a working royal.
And Thursday is an important date in her agenda, with an engagement alongside the Queen and the Duchess of Cornwall.
It is the first time the three generations of royal women have carried out an official visit together, and to mark the occasion the royal trio will visit luxury store Fortnum and Mason.
There, they will unveil a plaque to mark the renovation of Piccadilly.
And after the London event, Kate will be by the Queen's side again when she and the Duke of Edinburgh head to Leicester on March 8.
