Celebrities battle blisters in Comic Relief desert trek
Celebrities including Lorraine Kelly, Dermot O'Leary and Scott Mills have begun a five-day trek across the Kaisut Desert, in north Kenya, for Comic Relief.
Along with Kara Tointon, Olly Murs, Ronni Ancona, Nadia Sawalha, Peter White and Craig David, they will cover 100 km (62 miles) while battling stubborn donkeys and painful blisters.
A BBC One documentary about the trek will be shown ahead of this year's Red Nose Day on 18 March. Proceeds will help to prevent thousands of people in Africa from going blind.
