Ladbrokes looks at the odds for the highly-anticipated Makerfield by-election set for June 18.
The by-election gives Greatest Manchester Mayor Andy Burnham the chance to become an MP
Burnham is widely tipped to be a challenger to Keir Starmer's Labour party leadership, and by-election win could be the first step in that race.
In what would be one of the biggest by-elections in quite some time, Labour are tipped for victory in Makerfield according to the Ladbrokes' latest odds

Ladbrokes recently looked at the Labour Party leadership odds, with Burnham tipped to replace Starmer, and we could be seeing the first part of that saga unfolding.
A by-election has been called in Makerfield after Josh Simons stood down from his post as MP, giving Burnham a route back into Westminster.
There won't be another Labour candidate contesting Burnham for a spot in the by-election, with no other candidates being shortlisted.
The latest Makerfield by-election odds have Labour as the odds-on favourite to win, suggesting that Burnham has a pretty solid chance at becoming an MP by the summer.
The odds above suggest that Labour are the most likely party to win the by-election, with Reform UK viewed as their most likely opposition for the June vote.
Due to the fact that this will be one of the most-watched by-elections in quite some time, expect Reform to give a real go at this one. Robert Kenyon will be the candidate, and party leader Nigel Farage suggested he's going to do what he can to 'cause an upset'.
This by-election could be one of the most significant in UK politics this year, with Burnham getting back into Westminster the first step he needs to take if he wants to challenge Starmer.
For what it's worth, just as Labour are odds-on to win the Makerfield by-election, Burnham is odds-on with Ladbrokes to become the next leader of the Labour Party.
