Model of Royal Yacht Britannia to parade down The Mall

Nearly 20 years since Royal Yacht Britannia was decommissioned, a model of the famous ship will take centre stage at the Queen's 90th birthday celebrations.

Puppeteers will carry the yacht in a parade down The Mall.

The carnival parade will take place on Sunday to celebrate the Queen's role as patron of dozens of charities and organisations.

Ala Lloyd, creative director for the patron's lunch, gave the BBC a tour of the model.
