Lewis Hamilton was left disappointed after dominating most of the Monaco Grand Prix.

Nico Rosberg snatched his second successive victory this season, and third in a row in the principality, after Mercedes made an error in judgment when sending Hamilton for a pit stop.

Rosberg reduced Hamilton's championship lead to 10 points as he profited from a safety car callout to head off Ferrari's Sebastian Vettel.

Daniel Ricciardo finished fourth ahead of Red Bull teammate Daniil Kvyat on the testing street circuit.

Fernando Alonso suffered another disappointing race for McLaren, failing to finish after another mechanical breakdown.

Alonso's teammate Jenson Button finished eighth to secure McLaren's first points this season.

Overtaking is notoriously difficult at the tight circuit, which winds its way through the narrow streets of Monte Carlo.
