The remaining semi-finalists must pull out all the stops when they are tasked with the daunting challenge of cooking a three-course fish lunch to celebrate 100 years of women's right to vote. John Torode oversees the kitchen as the amateurs face a high-pressured lunchtime service. The VIP diners include: Dr Helen Pankhurst, great-granddaughter of Emmeline Pankhurst - leader of the suffragette movement; Baroness Hale, president of the Supreme Court; former BBC chief news correspondent Kate Adie; broadcaster Dame Jenni Murray; space scientist Dr Maggie Aderin-Pocock; journalist Kirsty Wark; and leading female chefs and restaurateurs who are at the forefront of dining trends and have paved the way for culinary excellence. The contestants must each serve one dish of their own creation on the specially designed menu. Under the watchful eye of John Torode, the amateurs are challenged like never before to deliver dishes of an exceptional standard. Once service is complete, it's back to the MasterChef kitchen, where all seven cooks are challenged with creating one plate of food inspired by someone they admire. With two hours to perfect their dishes, the chefs must go all out to impress judges John Torode and Gregg Wallace. After this challenge, one amateur cook will leave the competition and only six will remain to continue the battle for the MasterChef champion 2018 trophy.
