Jun.24 (GMM) Next weekend's British grand prix is the first formula one event staged at Silverstone to completely sell out.

It had already emerged that all tickets for Sunday's race day had been snapped up, but it is now clear that Friday practice and qualifying will also be watched by a full house.

90,000 spectators will throng the Northamptonshire venue on Sunday, after capacity crowds of 65,000 and 85,000 watch local drivers Lewis Hamilton, Jenson Button and David Coulthard on Friday and Saturday respectively.

"The demand for tickets has been incredible," said circuit chief Richard Phillips.

"The atmosphere is going to be amazing."
