SILVERSTONE, England (AP) -- Lewis Hamilton and Kimi Raikkonen had the best times in Friday's practice session for the British Grand Prix as the sabotage scandal involving McLaren and Ferrari implicated a third team.

Hamilton, who leads the standings over McLaren teammate Fernando Alonso, clocked 1 minute, 21.100 seconds in the morning session at the 5.1-kilometer (3.2-mile) Silverstone circuit. Hamilton will try to extend his perfect eight-for-eight streak of top-three finishes in his rookie Formula One season.

Raikkonen, who won last week's French GP, was the fastest in the afternoon for Ferrari in 1:20.639. In the first session, he was second with 1:21.211, just ahead of teammate Felipe Massa in 1:21.2855.

The battle for supremacy between Ferrari and McLaren has been overshadowed this week by sabotage allegations. Ferrari fired technician Nigel Stepney after he allegedly sent a package of technical information to McLaren chief designer Mike Coughlan in April. McLaren subsequently suspended Coughlan, but would not say Friday whether he is still with the team.

FIA, motor sport's governing body, said both teams have agreed to cooperate with an investigation into the incident. Ferrari has also filed a criminal complaint against Stepney.

The allegations involved a third unnamed team on Friday. McLaren boss Ron Dennis said he had a meeting with two other teams Friday at the Silverstone circuit to discuss the situation.

"Over the next 48 hours, definitely more information will be available into insight and into motives and what lies behind some peoples' actions," Dennis said. "I am optimistic that some of the things will be established quickly. The first thing is confirmation that no intellectual property is on cars, and never has been and never will be, that belongs to another Grand Prix team."

Honda later released a statement stating that team boss Nick Fry had met Stepney and Coughlan at their instigation in June to discuss job opportunities at Honda.

"Honda would like to stress that at no point during the meeting was any confidential information offered or received," the statement said. "Nick Fry informed (Ferrari boss) Jean Todt and Ron Dennis of the meeting and has offered to provide any information required by Ferrari and McLaren."

Italian news agency ANSA reported that Stepney met with lawyer Sonia Bartolini late Thursday in the small northern Italian village called Pavullo. Police were present to officially inform Stepney that he is under investigation, and search his house for the second time after an initial search on June 21.

"I am very calm, I'm certain I will be able to demonstrate that I had nothing to do with what I am accused of," Stepney said. "I know justice takes a long time, but I am confident that in the end I will prove my innocence."

Alonso, the two-time champion with Renault before moving to McLaren this season, had a mixed day Friday. He was fourth in the morning in 1:21.675, and sixth later in 1:21.616. He won last year's race.

Hamilton leads the driver standings with 64 points, 14 ahead of Alonso and 17 in front of Massa with nine races remaining.

"To win at this race would be immense, but we have to be realistic with our expectations," Hamilton said. "This is one race out of 17, and as with all the Grands Prix, I will do my best to win for the fans."

There is another practice Saturday with qualifying in the afternoon. Sunday's race is 60 laps.
