Mel Giedroyc and Sue Perkins will return to host a third series of the BAFTA-nominated amateur cookery series Great British Bake Off, which will feature cookery writer Berry and acclaimed Master Baker Paul Hollywood judging the cakes, pastries and bread-making skills of 12 home cooks.
Lawson's new series Nigellissima will air in the autumn and will feature her unique take on Italian food.
"When I went to live in Italy when young, I said I'd do anything but clean lavatories; as a chambermaid in Florence, that is what I ended up doing! But I also learned about real Italian food, and by the time I'd left I had found my spiritual and gastronomic home," said Lawson.
"I wanted to make a series of my sort of Italian food, inspired by the ethos and the ingredients but fused with the way we live our lives, here, in the UK. I care about ease and accessibility, but I care most about passion and taste and it is these crucial Italian factors, I want to bring to the table and the television!"
Other shows launching on the channel include Ken Hom and Ching-He Huang's Eat, Drink, Cook China and The Hairy Bikers' How To Love Food And Lose Weight project, which will aim to get the British public leading healthier lives.
