BBC has announced that the comedian will take over from Dara O'Briain, who left the show in January after five years in the presenter's chair.
Jack said: "I'm very much looking forward to hosting You're Fired! and hope that the luckless candidates will see me as the friendly face at the end of a difficult time in their lives."
The show will also welcome comic Romesh Ranganathan, who will be a regular panellist each week. He said: "As a massive fan of The Apprentice, this is very exciting for me. I love You're Fired and am looking forward to putting all the questions to the candidates that people at home want to see asked. I also have a number of business proposals of my own that I think Lord Sugar will be pretty interested in…"
As well as a new look spinoff show, there will be a new face on the main show, as Claude Littner replaces Nick Hewer as one of Lord Sugar's advisors. Baroness Karren Brady returns as the other advisor.
Claude said earlier this year: "If the candidates think I am soft and fluffy, they haven't been watching me on The Apprentice over the past decade. I will now be assessing their performance in the process, individually and within their teams.
"I will be reporting to Lord Sugar to play my part in ensuring that his personal investment of £250,000 goes to the best candidate. I'm ready, and this won't be a walk in the park!"
The businessman is a familiar (and ferocious) face to Apprentice viewers already thanks to his appearance in the penultimate episode of every series where he grills the final candidates on their CVs and business plans.
