Housemates won't be able to nominate Marcus on Wednesday night, after Siavash picked him to be immune from eviction.For this week's shopping task, the housemates have been re-enacting Tudor times, with Siavash playing King Henry VIII.
Karly, Sophie, Angel, Sree, Rodrigo and Freddie are his wives, Kris and Charlie are courtiers, Noirin and Lisa are the cooks, and unlucky Marcus is the Village Idiot.
Siavash has already chosen Charlie to escape nominating on Wednesday and Big Brother gave him one last choice to make during his reign as King.
The stylist was called to the Diary Room on Wednesday morning and told to pick another HM who he wanted to bestow a Knighthood upon, effectively making them immune from nominations and possible eviction on Friday.
Siavash toyed with giving Freddie the honour, to avoid him being up for the boot for the third week running.
In the end though, he settled on Wovlerine-wannabe Marcus, telling BB he was picking the person that is closest to me.
Siavash - and the rest of the HMs - are unaware they will be nominating live on Channel 4 tonight. We hope TV bosses have the swear filter on when they finally realise!
