Everyone volunteers for SAS challenge

All of the housemates signed up to the SAS-style challenge when they were asked to confirm their involvement this morning.

Yesterday the housemates were told that an ex-member of the SAS who is highly skilled in the art of interrogation would be hijacking the house in the next few days.

They were given 24 hours to decide whether they wanted to voluntarily participate in the task and today they were asked to gather on the sofas to make their decisions.

Big Brother told the contestants who wanted to take part to raise their hands and all of them put their arms in the air.

Calista asked: "Is that everyone?"

They were then told that Big Brother would get back to them "in due course".
