Sep.7 (GMM) F1's governing body does indeed suspect that "one or more McLaren drivers" are involved in the espionage affair.

Following speculation at Monza on Thursday, a letter sent by FIA president Max Mosley to the teams has now come to light at the scene of the Italian grand prix.

Mosley wrote that the Paris body was recently "made aware" that McLaren drivers - rumoured to be Fernando Alonso and Pedro de la Rosa - "may be in possession" of evidence relating to the spy saga.

The rumours in Monza suggested that test driver de la Rosa sent to his countryman Alonso emails about secret Ferrari setup data, obtained originally by suspended chief designer Mike Coughlan in the famous 780-page dossier.

An FIA spokesman refused to comment on Mosley's request to the teams for their assistance in gathering new evidence, saying only that it would be "inappropriate to comment in advance of the World Motor Sport Council hearing" next Thursday.
