Great Britain's Alistair Brownlee was disqualified in the final race of the World Triathlon Series after failing to go around a buoy during the swimming on the Gold Coast.

The 30-year-old two-time Olympic champion was initially hit with a 15-second penalty, which was subsequently upgraded to a disqualification.

Brownlee, a former Bradford Grammar School pupil, was not in contention for the world title heading into the event.

Spaniard Mario Mola secured the overall title after finishing Sunday's event in second place.

Vincent Luis of France crossed the line first, with Brownlee's brother Jonny finishing eighth and fellow Briton Thomas Bishop 22nd.

Brownlee, from Bramhope, tweeted: "Really disappointed with today. I thought I had a decent race in me. First ever DQ in any sporting event.

"Was on the wrong side of the buoy and I've seen it on video. But was disorientated after being hit and held under the water in the roughest swim I've ever done."
