Big Brother: Ash, Christopher become power housemates

The power has returned to the Big Brother house with Ash Harrison and Christopher Hall becoming the latest housemates to receive it.

The pair have been granted the power of knowledge and will assume control over the diary room, providing Big Brother with two killer questions that they want him to put to each of their fellow housemates.

They will also take part in a task that will see them become psychiatrists and further probe the others about their time in the house.

The revelation that the power has returned saw some of the housemates speculate upon a mid-week eviction for which Ash and Christopher will decide upon the nominees.
