Boris Johnson’s attitude to risk has shaped British politics for the past three years. It made him Prime Minister in July 2019 and then helped him overcome the parliamentary impasse over Brexit by the end of that year. But his risk-taking has now eroded his authority to such an extent that he might not lead the Conservatives into the next election.
Even after the years of cultivating his “Boris” persona – as a journalist and as mayor of London – it was in 2019 that Johnson’s personality really started to have a serious bearing on British politics. Prior to the EU referendum, he behaved as any Eurosceptic Conservative MP ambitious to become PM might have done. Politically friendless, Johnson needed a grand cause to challenge the then chancellor George Osborne for the party leadership when David Cameron stepped down before the next general election: nothing was so obvious in the circumstances as advocating for Brexit.
