It's harsh of the organisers to say that there wouldn't be another GP in Britain as Cardiff doesn't sell out...please.....The capacity at the Millenium stadium is approaching 70,00..it still draws the biggest attendance of all the Gp's.
Bydgoscz sells out, fair play...but their capacity is approx 20,000 less than a third of Cardiff.
There would be ample support for another GP in the UK, given that there will be 3 in Poland, are 2 already in Sweden, and this year were also 2 in Denmark.
Coventry or Peterborough would be fine as venues.
