Big Brother 2013 spoilers: Dexter Koh immune, Sophie Lawrence faces eviction

Dexter Koh (Big Brother 2013)

Dexter Koh has become immune from eviction on Big Brother 2013 tonight in a big twist.

Following the latest round of Big Brother 2013 nominations last night, Charlie Travers, Dexter Koh, Jack and Joe and Sam Evans were all put up for the axe.

Tonight, one by one, they were each be given a special question from Big Brother in the privacy of the small task room: What's the least amount of money they would accept to leave the house?

Big Brother had given the housemates the option of choosing any figure between £1 and the full £100,000 prize money.

As Dexter chose the lowest amount - although still a rather large £88,000 - he was branded the least greediest housemate.

In reality however, the task was all a lie. Dexter isn't leaving and he's not getting the money.

As the least greediest housemate, he was rewarded with immunity from eviction, and had to chose someone to replace him.

With only six housemates and four already up, it didn't leave much choice, with Dexter having to pick either Sophie or Gina.

Unsurprisingly he went with Sophie over pal Gina, leaving her facing the axe alongside Sam Evans, Charlie Travers and Jack and Joe.

The change in eviction line up is unlikely to impact the result, with twins Jack and Joe and Charlie both the favourites to leave and remaining so after the switch.
