The Duke and Duchess of Cambridge will welcome military supporters into their palace grounds today to mark London Poppy Day.
The royal couple will meet staff and volunteers taking part in the Royal British Legion (RBL) appeal who will call at Kensington Palace as part of a tour across the capital on a 1960s Routemaster Bus.
Some 2,000 uniformed personnel, veterans and their supporters will hit the city's streets for the eighth annual event ahead of Remembrance Day to commemorate the end of the First World War in 1918.
Fundraisers will be at 80 Tube and train stations across London's transport network and at hubs including Covent Garden, where a stage has been created for military performances throughout the day.
Organisers are aiming to raise more than £1 million in a single day.
All funds will go towards the national Poppy Appeal fund-raising target of £37 million to allow the RBL to carry out its vital work.
The nation's biggest armed forces charity spends £1.6 million every week in direct welfare support and answers more than 170,000 calls for help.
A series of events will take place across the capital to mark London Poppy Day, starting in Covent Garden with RBL ambassador Barbara Windsor and the Poppy Girls, who will sing the appeal's official single The Call (No Need to Say Goodbye).
