Great British Menu returns for its 20th anniversary, presented by Andi Oliver. Chefs compete to cook a course celebrating great Britons at a historic banquet at Blenheim Palace.

Professional chefs compete to cook at a banquet celebrating the Olympic and Paralympic games.

The theme for this year's competition is inspired by Paddington's 65th birthday and a celebration of British animation and illustration – from cartoons to comics and computer games.

This year's theme celebrates 100 Years of Great British Broadcasting. Some of the most talented and skilled chefs from across the UK's nations and regions will be tasked with cooking mouth-watering dishes which celebrate UK broadcasting across the decades, both on the BBC and other channels.

The brief this year is celebrating British invention and innovation.

Great British Menu is back - and this time the nation's top chefs are competing to create incredible dishes which celebrate ‘a taste of summer' and pay tribute to 140 years of the Wimbledon Championships.

Across eight regional heats, 24 chefs will compete in the toughest competition of their lives. Their dishes must capture the tastes, smells and colours of summer, and pay tribute to the incredible history and prestige of Wimbledon. Just as the Championships attract the top sporting talent from around the globe, so the chefs must display the same passion and precision required to win at the highest level.

In each regional heat, they'll first have to impress one of the surprise veteran judges, who between them hold an incredible eight Michelin stars and whose identity won't be revealed until they walk through the door. The two highest-scoring chefs will then face the formidable panel of judges Oliver Peyton, Matthew Fort and, for the first time this year, restaurateur and food broadcaster Andi Oliver.

This year on Great British Menu the nation's top chefs are competing for the ultimate prize - the chance to cook at a banquet held at the Palace of Westminster, in celebration of everyday great Britons honoured by the Queen. In the year of the Queen's 90th birthday, the chefs have been challenged to showcase contemporary cuisine and demonstrate the transformation in British food during her historic reign. The 24 chefs competing have travelled the country meeting great Britons who have been recognised for their tireless and selfless work for charities, for their local communities or their country.
