A celebrity edition of the survival challenge kicks off tonight as part of this year's Stand Up to Cancer campaign. It sees some famous faces packed off to a deserted island with only basic resources to survive. Yep, celebrities, out in the wild, with none of their creature comforts - this could be utter mayhem. Taking on the adventure is comedian Dom Joly, Made in Chelsea's Ollie Locke, pop star Aston Merrygold, former Labour councillor Karen Danczuk, Dr Dawn Harper from Embarrassing Bodies and TOWIE's Lydia Bright.
