One of the joys of a recent career change is taking a slightly longer run in the mornings. I get up in the dark and hammer my way round the park with the Protforce detectives strolling behind (and breaking into a theatrical jog when I turn round). There is nothing more beautiful than watching the sun come up over a frosty London, and seeing the light begin to gleam on the tops of those high-rises – tastefully located – that I helped to greenlight, with Eddie Lister and Simon Milton, when we were running City Hall.
