This Red Nose Day night of TV will be Sir Lenny Henry’s last on hosting duties and W1A’s finest team has been drafted in to find his replacement.

Ian Fletcher (Hugh Bonneville), Siobhan Sharpe (Jessica Hynes), Will the intern (Hugh Skinner) and Tracey Pritchard (Monica Dolan) reunite to hold interviews with some special guests in a bid to find Red Nose Day’s new host.

It’s been seven years since the W1A stars were last on TV together and there’s bound to be a few awkward conversations, especially when Sir Lenny arrives late to his meeting and comes face-to-face with his potential celebrity replacements, each one more ridiculous than the last.

Stars including Sir Mo Farah, Tom Davis, Richard Madeley and Wynne Evans face the panel to see if they have what it takes to fill Sir Lenny’s shoes. TV legends Lorraine Kelly, Pudsey, Bluey, Chesney Hawkes and Rustie Lee also make appearances, in fact, the queue for wannabe replacements gets so long, the panel will need to get on their Brompton bikes to get to the end of it.

Sir Mo Farah said: “I’ve watched Comic Relief for many years and think it is incredible. It’s all about having a laugh but for a good cause. I knew a little about the character but when I turned up and saw the outfit, I instantly knew I wanted to be a part of this sketch and couldn’t wait to get stuck in. I loved acting and the team made it really easy and fun for me. Who knows, maybe this character could be Sir Lenny’s replacement!”

Sir Lenny Henry, said: “How dare they replace me? I’m only joking, I’m flattered that the incredible W1A team have come back together to make this sketch happen. It’s hilarious and the guest stars are absolutely brilliant too.”

The full sketch will air on BBC One from 7pm on 15 March 2024.

Money raised by Red Nose Day will go towards organisations helping to tackle some of the urgent problems faced by people here in the UK and around the world. This could include helping provide shelter for those that need it, putting food on plates, filling the shelves of baby banks, offering someone to talk to, or somewhere to be safe.
