Tennis star Stefanos Tsitsipas has announced he has split from his father after tearing into him following defeat against Kei Nishikori on the ATP tour in Canada. The Greek was looking to bounce back from his quarter-final defeat by eventual winner Novak Djokovic in the quarter-final of the men's singles in the Olympics in Paris.

Fans have hit out at the 'disgraceful' decision to not initially show Andy Murray's potential final match on BBC One. Murray, who will retire after the Paris Olympics, is competing in the men's doubles alongside Dan Evans, with the British pair to face Kei Nishikori and Taro Daniel of Japan in the first round. However, much to the dismay of some fans, the decision was made to broadcast Murray's match live on BBC iPlayer, with the women's rugby sevens clash between Great Britain and Australia being shown on BBC One instead.

The truth is a little more prosaic, and he has been teased by colleagues that he is resembled one of his favorite childhood cartoon characters. "Well done, SpongeBob," one friend texted me.' In the aftermath of a hard-fought, straight sets victory over Portugal's Joao Sousa, I used to watch it a lot.'
