Sir Chris Hoy won gold in the men's sprint at the World Cup track event in Kazakhstan.

Four-times Olympic champion Hoy added gold to his silver in the keirin on Saturday as Great Britain improved on a poor first two days in Astana.

Hoy, the 2008 sprint champion and one of the all-time great Olympians, beat Russia's Denis Dmitriev 2-0 in the best-of-three final.

The Scot had beaten Germany's Robert Forstemann 2-1 in the semi-final and team-mate Matt Crampton in the last eight. Britain’s Jason Kenny crashed in the last 16.

Team GB won a second medal and their third overall when Dani King took silver in the women's omnium behind Evgeniya Romanyuta.

King, who started the day in fourth place, climbed into second with victory in the individual pursuit. She then finished sixth in the scratch race and secured silver ahead of Li Huang (China) with second in the 500 metres time trial.

Becky James and Jess Varnish failed to make the keirin final. The event was won by Frenchwoman Clara Sanchez, ahead of Germany's Kristina Vogel and Russia's Ekaterina Gnidenko.

Alexander Edmondson and Glenn O'Shea took men's madison gold for Australia, ahead of Silvan Dillier and Loic Perizzolo (Switzerland) and Artur Ershov and Kirill Sveshnikov (Lokosphinx).
