Watch as the housemates take on a task set by Big Brother, live to the nation.
On tonight's live challenge Big Brother tests their knowledge of the world. An umpire (Nush was chosen for this role) was to read out country names and two competitor's (Cameron and Ray) must take it in turns to pin a flag onto a world map that pinpoints the country Nush read out. Cameron wins. He is to take five other people into the reward room and leave one person behind. It's Nush who is left alone for the evening.
