MONTREAL, Aug 12: Former women's world No 1 Martina Hingis and Czech Radek Stepanek, the highest profile couple in tennis, have broken off their engagement.

A spokesman for the ATP said on Saturday: “Radek asked me to pass on a message announcing that he and Martina Hingis have split up, they will remain good friends.”

The pair became engaged last November when Stepanek proposed to Hingis in Prague.
