Lewis Hamilton v Nico Rosberg: 'This is now a war zone'
BBC Sport looks at the battle between Mercedes team-mates Lewis Hamilton and Nico Rosberg during the first six races of the 2014 Formula 1 season.
The pair have finished first and second in every race so far, except the opening race in Australia, when Hamilton retired early on with a misfiring engine.
The rivalry between the two intensified during qualifying at Monaco, when a mistake from Rosberg meant Hamilton could not complete his final lap and thus secured Rosberg's pole. Despite an investigation Rosberg was cleared of any wrongdoing.
