Marcus and Siavash are up for eviction from the Big Brother house this week.

The pair will face the public vote after Big Brother attempted to clamp down on contestants who refused to nominate, by telling Charlie and Sophie in the Diary Room they would automatically be nominated by anyone who refused to vote.

The news was relayed to the other housemates via the plasma screen in the living room, which visibly irritated Siavash.

However he stayed true to his word, thus automatically nominating Sophie and Charlie, but it is still he who faces the public after receiving nominations from Charlie, Rodrigo, David and Lisa – all of whom also voted for Marcus.

Sophie also nominated the Wolverine wannabe.

Apart from Siavash’s default votes for Charlie and Sophie, David was the only other housemate to receive any nominations – he received two from Marcus and Sophie.

The eviction will take place on Friday (August 28).
