Meanwhile, EastEnders star Richie has odds of 10/11 to be evicted from the castle where this year’s competition is being held.
North’s odds make him the 11/10 favourite to win the ITV show, with Giovanna Fletcher behind at 19/11, according to Ladbrokes.
North, Richie and Fletcher is one of the celebrity contestants who have taken part in this year’s show, which is set at a derelict Welsh castle instead of the usual Australian bush.
Alex Apati of Ladbrokes said: “It looks as though Shane will fall at the final hurdle while the two-horse race between Gi and Jordan for this year’s crown is well and truly on.”
