Dexter & Gina likely to fight another day
Wolfy is the 4/9 favourite to face the BB chop this week with Dan the 9/4 second favourite.
Dexter and Gina have once again been nominated for eviction but given their ability to avoid the public vote, are considered outsiders at 7/1 and 20/1 respectively.
"Wolfy and Dan will be a little nervous given Dexter and Gina's capacity for survival and it looks almost certain that it will be between just two housemates this week," said William Hill spokesman Joe Crilly.
Jack & Joe and Sam head the betting at 4/1, while Sophie has drifted out to 9/2.
Big Brother winner: 4/1 Jack & Joe; 4/1 Sam; 9/2 Spohie; 7/1 Charlie; 8/1 Gina; 12/1 Callum; 14/1 Daley; 14/1 Dan; 16/1 Dexter; 20/1 Hazel; 20/1 Jackie; 25/1 Wolfy
Big Brother next eviction: 4/9 Wolfy; 9/4 Dan; 7/1 Dexter; 20/1 Gina
