The fact that Boris Johnson isn't the real Mayor of London has been clear to me for some time now. A month of Boris watching has made it pretty obvious that whoever is running London, it isn't him. However, I didn't expect to see that fact so painfully demonstrated on the evening news.
Because to call last night's BBC London report a car crash would be to wildly underestimate the extent of damage done to the Mayoral freeway infrastructure. This was a pile-up of almost Hollywood proportions.
For whatever reason, Boris had decided to park his behind on the middle lane of the M25, and was just waiting for the inevitable destruction. And as painful evasion piled upon catastrophic ignorance I almost began to feel sorry for the man.
But as it became clear that Boris really has zero clue about what is being done in his and our name, my sympathy turned into anger.
Because all of this time that we have been talking about 'Boris doing this and Boris doing that' we have been spouting nothing but hot air.
Because despite what we may have said, Boris is not the evil Svengali directing his right-wing minions or the Manchurian Candidate waiting to be activated by the higher command. He is not even the light-touch delegator that at best his team have tried to portray him.
He is none of these things, because he is doing none of these things. And not only is he doing none of these things, but he doesn't even know that he is not doing any of these things. So how do we know this?
Well at the weekend we discovered that Boris had 'decided' to scrap Europe's biggest anti-racism festival and replace it with an apolitical event. This was big news and many column inches were used up pondering on what this meant about the direction Boris wanted to take London and what it said about Boris as Mayor.
But what last night's BBC London report showed in painful detail, was that we had been completely wasting our time. Because not only did Boris not decide to scrap the event, but he didn't even know that that was what had been decided, or even appear to know why it would have been.
So when his cultural advisor Munira Mirza pontificated in the Guardian about why her boss had made this important cultural decision, it was actually the case that not only had he not made that decision, but that he didn't even know that that decision had been made until informed about it by the BBC.
Now when Boris came into power we were all treated to photos of Boris at his desk, Boris on the phone and Boris directing colleagues. At the time these seemed incredibly staged but looking back at them now, they seem almost theatrical in their posing.
Because like those pictures we have of ourselves as kids when we dress up as doctors or policemen or teachers, these pictures were of Boris playing as London Mayor. And as last night's report showed, he is now seriously in danger of losing the game.
