Kirstie Allsopp and Louise Redknapp have signed up to take part in Sport Relief Does The Apprentice.

The charity episode of the show will feature teams of male and female celebrities completing a challenge in a bid to impress Sir Alan Sugar.

Allsopp and Redknapp will be joined by Lisa Snowdon, sports presenter Clare Balding and Ann Summers chief Jacqueline Gold on the female team.

They will face I'm A Celebrity... winner Phil Tufnell, broadcaster Hardeep Singh Kohli, TV presenter Nick Hancock, Lembit Opik MP and former Sun editor Kelvin MacKenzie.

The teams will be given the challenge of naming and stocking adjoining stores in London's West End in an attempt to make the biggest profit. They will also be required to take a hands-on approach to persuading fellow celebrities to buy their products.

The show will air on BBC One on March 12 and 14 as part of the Sport Relief weekend.
