The first five celebrities undertake three tough culinary challenges in a bid to prove their cookery talent to judges John Torode and Gregg Wallace.

The first week of heats continues as the four remaining celebrities face three more culinary challenges, battling for a place in the semi-finals. The first challenge is a relay invention test, and it's all about teamwork. Split into two teams, each team must create a main course and a pudding between them, using a guineau fowl for the main and tropical fruits for the pudding. Each team member has 25 minutes to make their contribution to the dishes, but they can't communicate with one another, so each cook must try and work out what the dishes are meant to be from the clues left behind by their teammate, and then carry on. For the final 15 minutes, the team members come together to finish the dishes, but will the celebrities be able to create something successful? Next, the teams are sent out on their first mass catering challenge. They have to make lunch for over 100 members of staff at the Emirates Stadium, home to Arsenal Football club. The two teams must devise, prepare and serve the lunch, catering for various tastes while creating meat-based, vegetarian and dessert dishes in volume. As the battle for a semi-final place reaches its climax, the four celebrities must now cook a faultless two-course meal that will not only be judged by John and Gregg, but also by past Celebrity MasterChef champions Sophie Thompson (2014), Emma Kennedy (2012), and previous finalist Wayne Sleep (2014). Only the best two contestants can earn a semi-final place and come one step closer to winning the title of Celebrity MasterChef 2015. For those who don't make the grade, the journey ends here.

The second heat week sees five more celebrities enter the MasterChef kitchen to undertake three tough culinary challenges in a bid to prove themselves to judges John Torode and Gregg Wallace. Battling for the crown are actor Laila Morse, former rugby world captain Neil Back, former member of 80's pop group The Communards Richard Coles, singer and songwriter Amelle Berrabah and Blue singer Simon Webbe. The first challenge for the five hopefuls is the Mystery Box; the infamous test of imagination and creativity. They must use the given ingredients including king prawns, noodles, chilli and mango, as well as a larder, to create just one dish - sweet or savoury. With nerves running high and just 50 minutes to create something from scratch, the celebrities must think on their feet to impress the judges. The celebrities are then split into two groups to take on the challenge of cooking for the first time in a restaurant kitchen, preparing dishes for paying customers. Richard and Amelle are sent to Asia De Cuba in the West End, while Laila, Neil and Simon head to Zebrano in the City of London. The celebrities in both kitchens soon learn that the pressure of a restaurant in full service has to be experienced to be believed. In the final test of culinary creativity, it's back to the MasterChef headquarters. The contestants are asked to prepare a two-course menu of their own design in just one hour. The celebrities work furiously in a last attempt to prove themselves to the judges, because at the end of this test one of them will be going home.

However, one takes over the work of the other without any verbal communication, before the two come together at the final stage.

This episode features the last of the heats, as the battle for the last two places in the semi-finals reaches its climax. The first challenge is a Relay Invention Test, and it's all about teamwork. Split into two teams, each team must create a main course and a pudding between them using turkey for the main, berries for the pudding and a range of fruits, vegetables, herbs and spices. Each team member has 25 minutes to make their contribution to the dishes, but they can't communicate with one another, so each cook must try and work out what the dishes are meant to be from the clues left behind by their teammate and then carry on. Then for the final 15 minutes the team members come together to finish the dishes The celebrities then remain in their teams and are sent out on their first mass-catering challenge, making lunch at Bisham Abbey National Sports Centre in Buckinghamshire for 80 elite athletes, including members of the Great Britain men's hockey team. With an array of ingredients, the two teams must devise, prepare and serve the lunch, catering for various tastes while creating meat-based, vegetarian and dessert dishes in volume. Then it's back to MasterChef headquarters for the final test. The four celebrities must now cook a faultless two-course meal that will not only be judged by John and Gregg but also by past Celebrity MasterChef champion Lisa Faulkner (2010), previous finalist Christine Hamilton (2010) and semi-finalist Christopher Biggins (2014). With their last chances to impress for a semi-final place, emotions in the kitchen are running high, and the pressure proves too much for some contestants. The celebrity judges deliver some frank and cutting responses to some of the dishes, but others fare much better. This is the last chance for the contestants to earn themselves a semi-final place and come one step closer to winning the title of Celebrity MasterChef 2016. For those who don't make the grade the journey ends here.

After four weeks of intense competition it's the first of the semi-finals, and the best cooks remain. The show kicks off with the celebrities' toughest challenge so far - cooking a feast for 70 guests in specially constructed marquee kitchens in a freezing field - so conditions are tough! Split into two teams, it's a race against the clock as the celebrities must design and create four mouthwatering dishes each (meat, fish, vegetarian and dessert) from a selection of ingredients including saddle of lamb, hake, whole salmon and quail, as well as a selection of fruit, vegetables, herbs and spices. Next it's back to the MasterChef kitchen, where they face an Invention Test with a difference. Each contestant is given their favourite ingredient to work with and, along with a well-stocked larder, has 90 minutes to create a dish that celebrates their chosen ingredient to keep them in the competition. Favourite ingredient choices range from mackerel to scallops, chicken breasts to chicken thighs and haggis. At the end of this challenge more celebrities will be going home, and their dream of being Celebrity MasterChef champion 2016 will be over.

It's the last of the semi-finals, and the remaining six celebrity cooks continue to battle for the MasterChef title. Their first task is the Great Classic Dish Test. Each of the six benches in the MasterChef kitchen contains the ingredients and recipe to make a different classic dish from around the world, including chicken kiev, a Portuguese fish stew, lamb koftas and queen of puddings. To stay in the competition, the celebrities must pick a bench at random and then perfectly cook the dish that's on it. Next, the remaining five celebrities face their most daunting challenge yet - to prepare a five-course dinner for the Chelsea Pensioners in celebration of HM the Queen's 90th birthday. However, they won't be cooking their own dishes. They will be cooking the menu of one the country's greatest chefs - Nigel Haworth of Michelin-starred Northcote Manor. Under his guidance, and following a recipe, they will each have to recreate one of his dishes, but to succeed they will have to master ideas and techniques they could never have imagined. Finally it's back to the MasterChef kitchen, where the final five must each create one exceptional dish that celebrates the life of someone important to them. The celebrities must impress John and Gregg by showing that they can put passion into their dishes and have the heart and determination to remain in the competition. The greatest cooks in the world are able to show emotion through their food - will our remaining cooks be able to do the same?

It's Finals Week on Celebrity MasterChef, and the four remaining cooks continue to battle for the Celebrity MasterChef title. The celebrities' first challenge is their most daunting yet - John's Palate Test. John cooks a highly complex dish - Korean fried chicken with Asian salad - which the celebrities have to taste and then identify the ingredients in. They then have one hour and fifteen minutes to recreate the dish themselves. Then, in their last challenge as a quartet, the celebrities must cook two dishes of their own design for four of the country's most feared restaurant critics for a place in the final three. Serving food to these masters of the dining room is a daunting task for even the most adept chefs, and the celebrities' choice of dishes are key to securing them a place in the final. Will their ingredients, flavours and presentation be enough to impress, or will they fall short of the mark and lose their chance to be Celebrity MasterChef? By the end of tonight's show only the three best cooks will still be in the running for the title.

It's the Celebrity MasterChef final. Twenty celebrities started the battle to be crowned MasterChef Champion 2016 - now only three remain. After six weeks of gruelling challenges, one of the remaining three contestants will be crowned champion. Just two tough challenges stand between them and the title. The remaining celebrities must draw on everything they have learned over the past few weeks and cook to the very highest of standards if they are to impress judges John Torode and Gregg Wallace. Their penultimate challenge is the toughest and most daunting of the competition - the Chef's Table - hosted by Michelin-starred chef Atul Kochhar at Benares. The three finalists must deliver food of an exceptional standard to impress some of the best chefs in the country - Cyrus Todiwala OBE, Alyn Williams, Sabrina Ghayour, Romy Gill MBE and Ed Baines. As they battle to master new techniques and unfamiliar ingredients in Atul's dishes, will they hold their nerve or is the pressure to deliver too intense? Then it's back to the MasterChef kitchen for the last time, where the three finalists must now cook and present a faultless three-course meal for final judgement by John and Gregg. It's their last chance to prove they have what it takes to be crowned Celebrity MasterChef champion by showing true passion and creativity with their dishes. Who amongst this year's finalists is the true cooking star and worthy of a place in the Celebrity MasterChef hall of fame following in the 'food-steps' of previous winners Matt Dawson MBE, Nadia Sawalha, Liz McClarnon, Jayne Middlemiss, Lisa Faulkner, Phil Vickery MBE, Emma Kennedy, Ade Edmondson, Sophie Thompson and Kimberly Wyatt? Only one can be crowned Celebrity MasterChef champion 2016.
