There are credible accounts that Mr Sunak has become increasingly
querulous with aides and colleagues over the past few months as
nothing he has tried has moved the dial. He’s looked like a man
trapped by diminishing time, undermined by mutinous colleagues and
almost totally ignored by the voters. Not the master of his own fate.
By choosing to go earlier than anticipated, he played the last card in
his hand to take the initiative and command events, albeit only
fleetingly. I am also quite persuaded by those who say that it was a
fit of despairing anger by someone who can no longer bear doing the
job. Living under a decomposing regime is not a pleasant experience
for those being ruled by it. Presiding over one must be miserable as
well. It turns out that the prime minister was among those yearning to
escape the purgatory of zombie government.
