Even a cynical old bugger like me has been walking around all day with a huge grin on my face following the announcement that London is to host the 2012 Olympics.

The news seems to encapsulate all those idealistic Olympic values: preparation, determination and a will to win.

But the euphoria won't last.

It won't be long before the first downbeat newspaper article appears warning that London can't cope with/won't be ready in time for/can't afford the Olympics.

I give it a week. Tops.
