As the 65th anniversary of the coronation approaches, Fiona Bruce and members of the Antiques Roadshow team head to Edinburgh to the Royal Yacht Britannia for a special royal edition of the programme. The programme looks back at the reign of HM the Queen through objects brought in by those who worked for her and played a part on formal occasions. From engine room staff and cooks, to a maid of honour at the coronation and the secretary general of the Commonwealth, each person shares their memories of HM the Queen at work and at leisure. Britannia was one of the Queen's favourite residences and she is on record as saying 'This is where I can truly relax'. Antiques Roadshow experts aboard are Geoffrey Munn, Hilary Kay, Adam Schoon and Henry Sandon. Items include early and rarely seen photos and footage of the Queen, hand drawn Christmas cards to a childhood friend signed 'Lilibet', and interior designs for the Royal Yacht painted by Sir Hugh Casson.
