The SNP, Ukip and immigration are likely to dominate the first Labour leadership debate, according to the betting company Ladbrokes.
Ladbrokes is taking bets on the most likely buzzwords to feature in the debate - with Ukip and the SNP featuring highly.
Ukip has odds of 1/10 in featuring, while the SNP and immigration are each on 1/5 odds, showing how the problems of the 2015 General Election are looming over the party's future.
Tony Blair is also likely to haunt the party's discourse, with odds of 1/2 on featuring.
On even odds are the phrases "connect with the voters", "on the doorstep" and "exit polls" - all of which hark back to Labour's unsuccessful General Election campaign where it sunk to its lowest level in three decades.
Other phrases that could feature in the debate are "Edstone" (2/1 odds), "we spent too much" (5/1 odds) and "terrible leader" (10/1 odds).
The first debate between the candidates will be hosted by the BBC on 17 June. It will be moderated by Laura Kuenssberg and will be shown on Newsnight on BBC Two and the BBC News Channel.
