Celebrities including Lydia Rose Bright, Sam Thompson, James Dunmore, Sir Mark Thompson and Helen Fospero are to take part in a trek in the jungles of Borneo to raise money for children's charity Barnardo's.

The challenge takes place May 12-19, and Bright, an ambassador for the charity, commented 'I'm so excited to be taking part in this challenge for such a good cause although I'm a bit nervous! As my mum Debbie Douglas has been a foster carer for 25 years, I have grown up surrounded by foster children and it has been a wonderful experience. I'm now proud to support Barnardo's and the many different services it provides to support vulnerable children'.
