Lewis Hamilton accepted the blame for the errors that led to him finishing sixth in Sunday’s Hungarian Grand Prix.

The world champion made a bad start, ran off the road on the first lap and later damaged his car in a collision with Red Bull’s Daniel Ricciardo. Hamilton said: “I was all over the place. I really don’t have any words to describe what happened. It was a really bad performance from me.”

Ferrari’s Sebastian Vettel won ahead of Red Bull’s Daniil Kvyat and Ricciardo. Running fourth on the first lap after a bad start, Hamilton ran wide at the chicane, dropping to 10th place, fought back up to fourth place and then broke his front wing colliding with Ricciardo after a restart following a safety car period.

Hamilton added: “I don’t know if it was a lack of concentration or what. I pushed right to the end but there were so many obstacles. It’s like there were two different directions and each time I chose the wrong one.”

He admitted it was “bizarre” that in the circumstances he had extended his championship lead over Mercedes team-mate Nico Rosberg.

Vettel took the surprise win after taking the lead from Hamilton off the start line into the first corner. Vettel’s victory – his second of the season – was dedicated it to French driver Jules Bianchi, who died last Friday. Behind him, team-mate Kimi Raikkonen passed Rosberg into Turn Two for second place as Hamilton dropped back to fourth.
