Nico’s home win prompts protest

Nico Rosberg’s Monaco Grand Prix victory has been overshadowed by protests launched against Mercedes by two of their main rivals.

Red Bull and Ferrari lodged complaints before the race over secret tyre tests conducted by the team in conjunction with Pirelli on May 15-17 in Barcelona.

Upon hearing representations from the three teams and Pirelli, stewards confirmed they will write a report to the FIA “who may bring the matter before the International Tribunal”.
