Latest Developments on Odds & Favourites:

  • 24th October 2022 – Boris Johnson announced he would not be running late on Sunday, seemingly clearing the way for Rishi Sunak to become Prime Minister, although odds are still being offered for Penny Mordaunt.
  • 22nd October 2022 – The Bookies seem to think it’ll be Sunak and Boris as Mordaunt’s chances have gone from 17% to 10% overnight.
  • 21st October 2022 – Yesterday, our tracker had seven names on it. Today we’re down to just three. It seems certain that our next Prime Minister will be one of Rishi Sunak, Boris Johnson, or Penny Mordaunt. Johnson has climbed up to second over the past 24 hours, but the bookies still have Sunak as firm favourite.
  • 20th October 2022 – Well here we are, set for our sixth Prime Minister in just five years. After just 44 days as Prime Minister, Liz Truss resigned from her post. Rishi Sunak is the early favourite, with Penny Mordaunt in second. Most surprisingly, Boris Johnson, who was removed as PM just a matter of months ago is the third favourite with the bookies.

About the data

We monitor trends in odds on key markets of interest by tracking a range of UK and international bookmakers. The update frequency varies, but is clearly shown on all our tables and charts. After fetching odds direct from bookies, we convert them to implied probability to make them easier to manage (read more on implied probability and converting from fractional to % probability). We then take the mean average implied probability to get a consensus view across the betting industry. This average implied probability is what we show on our charts and tables.
