British women's No. 1 Katie Boulter is out of the Australian Open after a second round defeat to Veronika Kudermetova in Melbourne.

For the first time, six British players have won first-round matches but Boulter had to work extremely hard to join Jack Draper, Emma Raducanu, Jodie Burrage, Harriet Dart and Jacob Fearnley in round two.

Katie Boulter has crashed out of the Australian Open in the second round after a shock defeat to Russian world No.75 Veronika Kudermetova. British No.1 Boulter, the world No.25, was the favourite to progress but has been unable to join her fellow Brit Emma Raducanu in the third round,
