Boris Johnson has weathered many storms during his premiership. But the latest, a vote of no confidence triggered by members of his own party, may yet prove fatal. Though Johnson survived the vote — 211 to 148 — as evident from his predecessors, the process itself is a political kiss of death.
Theresa May won her vote in 2018, 200 to 117, but stepped down a few months later. John Major won his vote in 1993 but did not survive the next general election. Margaret Thatcher won her vote in 1989, but her leadership was put to a vote again the following year, whereupon, her popularity was compromised and she decided to bow out.
