British GP: Hamilton continues Mercedes dominance final practice

Silverstone - Lewis Hamilton was fastest in the final practice session before qualifying for the British Grand Prix in front of his home fans.

The Mercedes driver outpaced Sebastian Vettel, who has a 20-point lead over him in the Formula 1 drivers' championship.

Hamilton posted a lap of 1 minute, 28.063 seconds at a rainy Silverstone circuit that was 0.032 seconds faster than Vettel.

As it happened: British GP - 3rd Practice 

Valtteri Bottas, who is third in the championship, was third fastest on Saturday morning. Qualifying is later in the day ahead of Sunday's race.

Meanwhile, Daniel Ricciardo's pursuit of a sixth straight podium finish has been set back by a five-place grid penalty at the British Grand Prix.

The sanction is the result of the Australian having to change the gearbox on his Red Bull before it had been used in six consecutive F1 races.

Ricciardo is fourth in the drivers' championship heading into Sunday's race at Silverstone.
