Hamilton on the drift
Lewis Hamilton is struggling to retain favouritism for the F1 drivers' title after his second retirement of the season in Canada.

The Briton was forced out of the race, won by Red Bull's Daniel Ricciardo, with brake failure.
Hamilton's Mercedes team-mate Nico Rosberg was able to nurse his car to the finish line in second place to extend his lead at the top of the standings to 22 points.
And plenty of layers now make the title race a pick 'em between the Silver Arrows pair, although Rosberg can be backed at 11/10 (Betfred) with Hamilton no better than 10/11.
Despite Mercedes's race-day struggles in Canada the drivers' title still looks like a two-horse race with Ricciardo and Sebastian Vettel - who took third place in Canada as Red Bull got both their drivers on the podium - both 40/1 and it's 200/1 bar.
Mercedes still have a vast lead in the constructors' betting and are 1/500 to take that title.
"What a difference a week can make - Hamilton is no longer a certainty and Red Bull are back in the race," said William Hill spokesman Rupert Adams.
