He's the very embodiment of Etonian privilege... no matter what he does he has the confidence, charisma, connections, chromosomes and colouring to always fail upwards, and as a result believe he's done a good job. 200 years ago he'd have joined the army and very quickly been promoted to colonel and given a cushy staff job somewhere harmless.
And now apparently he's refusing to rule out continuous proroguations of parliament! It's not a sign of strength to constantly be running and hiding from the those with the power to question you (as well as running and hiding from small groups of polite protestors, or paternity suits).
