What would you do if…

1. You’re a Member of Parliament,
2. You want to be Mayor of London, and
3. There’s a big debate in Parliament about a major London issue?

If your answer is “don’t turn up”, then congratulations: you are admirably qualified to be the Conservative candidate.

(Yup, that’s right – Boris Johnson didn’t turn up to this week’s debate on Heathrow’s expansion.)
