Great British Menu's winning chefs arrive at the Palace of Westminster to cook for the banquet of great Britons.The chefs have been selected because their dishes showcase contemporary British cuisine and demonstrate the transformation in British food during the Queen's historic reign.Welcoming them is banquet host Lindsay Hoyle MP, deputy speaker of the House of Commons. The chefs are overawed by the grandeur of the Houses of Parliament. It is their first time here and the first time they have seen the kitchens, but as they discover, their prep time is limited - the Houses of Parliament kitchens are a busy machine.The banquet guests include individuals from across the UK who have been honoured for their work for charity, for their community, or for their country.They include military hero Johnson Beharry VC, headteacher Kamal Hanif OBE, charity fundraiser Lynne McNicoll OBE, Anna Kennedy, honoured for her work for children with autism, 18-year-old Louise Greer, who campaigns for riding for the disabled, RNLI volunteers, food producers and women such as Justice Williams and Zoe Jackson who have received honours for their work with young people.Also present are guest judges Grace Dent, Kevin Gould and Enam Ali and veteran chef judges Michael O'Hare, Lisa Allen, Daniel Clifford and Simon Rogan.As the banquet is served, the chefs show just why they are amongst the best in the country, pulling off four stunning courses that leave the guests overwhelmed and delighted.
