Finland's Jari-Matti Latvala swept to a stunning victory in Rally Sweden, winning the final three stages on Sunday in his Toyota Yaris to claim his fourth victory in the race and climb to the top of the World Championship rankings after two events.

"It's amazing. New team, new car, our second rally and we're winning it straight away," an elated Latvala said after his 17th career win.
