Unlike the inestimable Henry Gee, I am not a 100 per cent supporter of everything Boris Johnson does and says - though I think a lot of people do underestimate him.
There's one thing, though, from my experience of visiting the Olympics last Friday, for which I award Boris a gold medal (or LOCOG or whoever thought of it). Quite unexpectedly, along with our Olympic tickets we found day passes for London Underground, busses etc in our jolly Olympics welcome pack.
Leaving aside this saved us around £30 on what was inevitably quite an expensive day out, it was such a good idea. It felt like a positive gesture - we were getting something for nothing we would otherwise pay for - and it encouraged people to use public transport to go to the games. Best of all, it looked like joined up thinking. I was a little worried that the tickets would only take us to and from the venue, but we happily made an excursion to Covent Garden (no, not the opera house) on the way back with no trouble.
Forget celebrating all those British medals. This, for me, was the real success of the 2012 Games.
