Frenchman Tony Estanguet beat his old rival Michal Martikan to claim a third Olympic gold medal in the canoe slalom single competition at the Lee Valley White Water centre.

Estanguet, winner of the event in Sydney and Athens, sliced through the choppy water of the tricky course, negotiating the 23 gates in style to stop the clock in 97.06 seconds.

Germany's Sideris Tasiadis was second after a storming finish while Slovakian Martikan, who won his country's first ever Olympic gold in Atlanta in 1996 and then topped the podium four years ago in Beijing, took bronze in 98.31 seconds.
