It's the 20th anniversary series of Great British Menu, and four chefs compete for Scotland with canapes, starters and fish dishes celebrating great Britons of the past for a banquet at historic Blenheim Palace.

The dishes are judged by the Michelin-starred Aktar Islam and include a beetroot-based book celebrating Sir Arthur Conan Doyle and Sherlock Holmes, and an inventive take on poaching haddock inside a humble flask that's inspired by four Scottish inventors.

The two highest-scoring chefs from Scotland 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 modern-day hero Ben Thompson, who after the RNLI saved his life in a traumatic event at sea, went on to volunteer for them as well as becoming a firefighter, saving lives both on water and land. He also recently won a Pride of Scotland award. How will he judge dishes celebrating great Britons of the past?

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