ISTANBUL, May 8 (Reuters) - Formula One's governing body said on Thursday that qualifying procedures would change after the Super Aguri team's withdrawal from the championship.

Race stewards at the Turkish Grand Prix said that with only 20 cars now participating, five rather than six would be excluded after each of the first two parts of Saturday qualifying.

That will still leave 10 cars fighting for pole position in the final 10-minute phase.

Super Aguri, who had been the 11th team on the starting grid, announced on Tuesday that they were pulling out due to financial difficulties.
