UK General Election odds: Reform set for historic win

• Reform are priced as the favourites to win the most seats at the next UK General Election

• Nigel Farage's party saw their odds of winning the most seats tumble after impressive local election results in May 2026

• Labour and the Conservatives remain the most likely to challenge Reform, while the Liberal Democrats, Green Party and Restore Britain are viewed as major outsiders.

Reform are currently priced as the favourites for a historic win according to the latest UK General Election odds.

There's a lot going on in the UK political scene, with calls for Keir Starmer to step down as Labour Party leader in the wake of his party's poor performance in the 2026 local elections.

Andy Burnham is viewed as the favourite to replace Starmer according to the next Labour Party leader odds, but some are anticipating more wholesale changes.

When it comes to the next UK General Election, Ladbrokes currently has Reform as the party most likely to win the most seats, with the assumed probability of that happening at just shy of 50%.

Labour are viewed as the party most likely to challenge Reform when it comes to winning the most seats, but the assumed probability of that happening isn't even 30% at the time of writing.

So much has changed in UK politics over the last few years that the Conservatives are as far out at 6/1 to be the party with the most seats to their name after the next UK General Election, with voters on the right expected to view Reform as a more attractive prospect.

Zack Polanski and the Green Party have seen a surge in popularity this year, but Ladbrokes is still pricing them as outsiders to win the most seats at the next General Election, sharing their 12/1 price with Restore Britain.

Despite Reform's showing in the local elections in May, Ladbrokes still has 'no overall majority' as the most likely outcome at the next UK General Election.

A Reform Majority is the most likely outcome if one part does achieve an overall majority, with the assumed probability of that happening currently sitting at just over 23%.

In the overall majority market, Labour are expected to be the party most likely to rival Reform, with an assumed probability of not even 13% at the time of writing.

The chances of any party winning an overall majority currently sits at just over 42%, with Ladbrokes currently viewing the current UK political scene as too divisive for any party to achieve a majority.

When will the next UK General Election take place?

While there have been rumours, or calls, for a vote of no confidence and UK General Election to take place soon, the latest odds suggest that's unlikely to happen.

Ladbrokes has a market available for when the next UK General Election is going to take place, with 2029 or later priced as the most likely option at the time of writing.

There's just over an 11% chance of a General Election taking place at any point this year, with the assumed probability of one taking place in 2027 rising to just shy of 17%.

All of these markets and odds highlight just how unpredictable the current UK political scene is, so make sure you stay tuned to Ladbrokes' politics hub for all the latest news and betting tips.

Interestingly, Ladbrokes has several UK General Election specials on offer for customers to bet on right now, with Thomas Skinner running as a Reform Party candidate and Boris Johnson to join Reform UK before the next General Election both listed.
