I appreciate this is all 'ifs and buts'......but for the sake of the argument, and as it has almost quadrupled in less than two years, if in 5/6 years the budget has increased to, say, �20bn or more, are there people on this site who still think it is worth it?
To answer your Q olddutch, it strikes me that the Olympics is becoming a new Dome where the cost just keeps on creeping up and up and up, so I am going to hazard a guess that this time next year the budget will have risen to �12bn, the year after that �15bn and so on.
Are we really that desparate for a velodrome in the East End? Wouldn't the billions be better off elsewhere? What about trying to prop up pensions? I'm sure in 2020 the little old lady in Dalston will be pleased she's living on next to nothing and freezing so that she could have a velodrome just down the road!
