Honda quit last December and BMW announced in July it was pulling out at the end of the season.

The Renault team admitted at the hearing that it had conspired with Piquet to cause the crash in breach of the international sporting code and F1 sporting regulations, FIA said.

The team's internal investigation had shown that Briatore, Symonds and Piquet had conspired to cause the crash; and that no other team member was involved in the conspiracy, the statement said.

Renault in its mitigation said that it had accepted the offence, cooperated fully in the investigation and ensured that Briatore and Symonds had left the team.

In addition it had apologized unreservedly to FIA and to the sport and was committed to paying the costs incurred by FIA in its investigation. Parent company Renault will also make a significant contribution to FIA safety-related projects.

Piquet, who was granted immunity from individual sanctions in return for his evidence, also apologized unreservedly for his part in the conspiracy.

Alonso 'was not in any way involved in Renault F1's breach of the regulations,' the council ruled.

Noting Briatore's part in the affair, the World Motor Sport Council said that for an unlimited period 'the FIA does not intend to sanction any international event, championship, cup, trophy, challenge or series involving Mr Briatore in any capacity whatsoever, or grant any license to any team or other entity engaging Mr Briatore

in any capacity whatsoever.'

FIA will not permit Briatore access to any areas under the FIA's jurisdiction and 'does not intend to renew any superlicence granted to any driver who is associated (through a management contract or otherwise) with Mr. Briatore, or any entity or individual associated with Mr. Briatore.'

FIA said it had taken account 'not only to the severity of the breach in which Briatore was complicit but also to his actions in continuing to deny his participation in the breach despite all the evidence.'

A similar ruling will apply to Symonds for a five-year period. The council said it had taken into account Symonds' acceptance that he took part in the conspiracy and 'to his communication to the meeting of the World Motor Sport Council that it was to his 'eternal regret and shame' that he participated in the conspiracy.'

The FIA ruling has come ahead of this season's Singapore Grand Prix Sunday.
