It's the 20th anniversary series of Great British Menu, and four chefs - one of the strongest groups ever seen in the kitchen - compete for central and eastern England with canapes, starters and fish dishes celebrating great Britons of the past for a banquet at historic Blenheim Palace.

The dishes are judged by Michelin-starred Tommy Banks and include a Tolkien-inspired pomme souffle ring and a complex fish wellington in which only a single slice is served on the plate.

The two highest-scoring chefs from central and eastern England must go head-to-head and cook their six-course menus again.

They need to impress a panel of exacting judges: Michelin-starred chef Tom Kerridge, former Great British Menu Champion of Champions Lorna McNee, and comedian and food podcaster Ed Gamble. The guest judge is Olympic heptathlete Dame Denise Lewis, who won gold in Sydney 2000 and is now president of UK Athletics. How will she judge dishes celebrating great Britons of the past?

Only one of the chefs will triumph and go through to represent central and eastern England at the national finals.
