Valtteri Bottas edges Lewis Hamilton as Mercedes dominate again at Silverstone

The second 90-minute practice session gets under way at 3pm.

Valtteri Bottas saw off Lewis Hamilton to finish fastest in opening practice for the 70th Anniversary Grand Prix.

On Thursday it was announced that Bottas will be retained by the Silver Arrows for 2021 and, at a sweltering and deserted Silverstone, the Finn edged out Hamilton by just 0.136 seconds.
