GP2 points leader Davide Valsecchi will start from the back of the grid for the Silverstone feature race after both receiving a grid demotion and being excluded from qualifying.
The DAMS driver had qualified 12th, but was initially given a 10-place penalty for overtaking during a red-flag period in practice.
Valsecchi was then one of four drivers excluded from qualifying altogether due to what a GP2 statement called "failing to satisfy a technical regulation relating to the quantity of fuel available after the session". Also affected were Valsecchi's DAMS team-mate Felipe Nasr, iSport's Marcus Ericsson and Coloni's Stefano Coletti, who had qualified 11th, 18th and fourth respectively. Both DAMS drivers had stopped on track near the end of qualifying.
Caterham's Giedo van der Garde, who was 10th in the session, will drop 10 places for overtaking after the red flags were shown as well.
Fabio Leimer will start on pole position for Racing Engineering, while Valsecchi's nearest title rival Luiz Razia is eighth on the grid. The Brazilian is only one point behind Valsecchi in the standings following his dramatic Valencia win.
