John Jones is the sort of voter that British Prime Minister Boris Johnson cannot afford to lose — but already has.

Jones, who backed Johnson's Conservatives in the national election three years ago when the party swept to a landslide victory, regrets his decision after the prime minister broke his own coronavirus lockdown laws to attend alcohol-fueled gatherings in his Downing Street office.

The 75-year-old retired hospital supplies manager said he won't vote Conservative again until Johnson has gone.
