2019 Favorite To Be New British Prime Minister Boris Johnson's Exit Date

Boris Johnson’s most likely exit date has been revealed as 2019, with UK books pricing up how long the new Prime Minister will last in 10 Downing Street.

2019 is the clear favorite for when his time as PM will come to an end be at +225, meaning British bookmakers think it’s most likely he leaves in his first year.

The next most likely exit date is both 2020 and 2022, which are +350 to be the year that he leaves the position.

Bettors are backing the newly-appointed PM to leave in 2019 too, with 24% of all bets in the market backing an early exit for Johnson.

Oddschecker spokesperson Callum Wilson: “The UK has watched Boris' price cascade further and further into the abyss of inevitability and now it's finally been made official.

"Based on the early reaction to his appointment, it's unlikely to be an easy ride for the former Foreign Secretary. Bookmakers give it a 30.8% chance he's out of No.10 before 2020."
