LE CASTELLET: Lewis Hamilton extended his championship lead and continued his relentless run of success on Sunday when he scorched to an emphatic victory ahead of Mercedes team-mate Valtteri Bottas at the French Grand Prix on Sunday.

The defending five-time champion repeated his pole-to-flag triumph of 2018 with a flawless drive to his fourth win in succession, sixth this season and 79th of his career.

Max Verstappen was fourth for Red Bull ahead of four-time champion Sebastian Vettel in the second Ferrari and the resurgent McLaren of Carlos Sainz.

Daniel Ricciardo was seventh for Renault ahead of Kimi Raikkonen of Alfa Romeo and Nico Hulkenberg in the second Renault with Lando Norris finishing 10th despite hydraulics problems in the second McLaren.

"It's definitely been a really good weekend," said a beaming Hamilton. "It's such a challenge out there and I live that, really trying to find the edge.

"I couldn't do it without this incredible team and we are creating history - and I am so proud to be part of it."

Bottas, who resisted a late charge from Leclerc, said: "Ultimately, Lewis was quicker today and I couldn't match his pace."

Leclerc said: "I gave it everything, but the Mercedes are just too quick."
