Mercedes one-two but incident blocks Hamiltons flying lap
Daniel Ricciardo takes third with Jenson Button 12th
The intense rivalry between the Mercedes team-mates Lewis Hamilton and Nico Rosberg has hit its first crisis after a controversial ending to the qualifying session for Sunday afternoons Monaco Grand Prix.
With a minute of the session remaining Rosberg, who had set the fastest time, locked up as he entered Mirabeau on his final lap and went on to the escape road. Behind him Hamilton was on a faster lap, one that would almost certainly have snatched the prize from the German and given the championship leader his fifth pole of the season in six races. But he was forced to abort his effort as the yellow flags were waved.
