Russia's Voinova and Shmeleva take gold

Russia's Anastasiia Voinova and Daria Shmeleva won women's team sprint gold on day one of the UCI Track Cycling World Championships in London after China duo Gong Jinjie and Zhong Tianshi were disqualified.

Gong and Zhong thought they had defended the title they won in Paris last year, but their celebrations were cut short at the Lee Valley VeloPark on Wednesday.

It was Voinova and Shmeleva who topped the podium following a restart, with the Chinese duo having to settle for silver due to an illegal change spotted by the judges during the final.

Shmeleva had taken a tumble following a false started after struggling to get out of her gate, but had the last laugh. Germany's Kristina Vogel and Miriam Vogel won bronze.

New Zealand's men made up for the disappointment of being runners-up to hosts France last year by going one better at the expense of the Netherlands.

Ethan Mitchell, Sam Webster and Edward Dawkins produced a great comeback to win a closely contested final, with Germany taking bronze ahead of the defending champions France.

Rebecca Wiasak took the first rainbow jersey of the event when she retained her individual pursuit title.

Malgorzata Wojtyra of Poland was no match for the Australian, who produced a dominant ride to lead the 3,000 metre race from start to finish and win by almost eight seconds.

Spaniard Sebastian Mora Vedri won scratch gold ahead of Mexican Ignacio Prado and Swiss rider Claudio Imhof with an impressive victory in the 15-kilometre final.

A Great Britain team, which included Bradley Wiggins in his first Track World Championships for eight years, laid down a marker by setting the pace in the men's team pursuit qualification and will return in search of gold on day two.
