A huge mural, painted by Rex Whistler in the Tate Britain's restaurant, has been restored as part of the gallery's £45m revamp.

Entitled The Expedition in Pursuit of Rare Meats, the frieze was painted in 1926 whilst Whistler was a student at the Slade.

Jim Diamond - who led the team that restored the painting - explained the process to BBC News.
