In a special one-off show Big Brother host Davina McCall will come direct from the Big Brother studios on Wednesday night to spring a surprise on the Housemates.

Following the 9pm highlights show featuring all the action from the past 24 hours in the house, Big Brother will announce to the House that each Housemate will be called, one by one, into the diary room to give their nominations LIVE on TV.

Each housemate will be given a strict amount of time to name the two housemates they wish to nominate. Only nominations given within this time frame, with full and frank reasons, will count.

Charlie is not eligible to nominate this week. During the Tudor task Siavash (in his role of Henry VIII) had to decide which one Housemate would lose the right to nominate. He picked Charlie.

Housemates will be gathered on the sofas to hear the results of the nominations later on.

Vote lines will open at 10 am on Thursday 25th June. Check www.channel4.com/bigbrother for details and terms.
