In the weeks since Sadiq Khan launched his re-election campaign, the mayor of London’s team have been briefing the national press about their fears for the upcoming vote. The two-times mayor is reportedly worried that, when Londoners go to the polls on 2 May, the outcome will be closer than widely predicted because of the new first-past-the-post voting system.

More likely the mayor is simply engaging in a bit of get-out-the-vote reverse psychology. After all, the pollsters have him 25 points ahead of his  nearest rival and he is the runaway favourite with the bookmakers.

If he does win the election for an unprecedented third term, Khan will once again be put in a position to make some big decisions affecting the built environment. So, what does his record over his first two terms tell us about how he might govern in a third?
