Biggins seems the obvious choice, although I am not a huge fan. It would be boring if he won,

James continues to shorten despite being up for eviction.

Christopher- 3.15

Sam- 8.6
Marnie- 10.5
Bear- 15

Some money is coming in quick for Bear which is concerning. Ricky closing the gap and could be favourite very soon. Marnie losing popularity quick. Heavy D has lost a huge amount of support and is now at 40/1.
