Britain's former world number four Johanna Konta has announced her retirement from professional tennis.
Konta, 30, reached the Wimbledon semi-finals in 2017 - the first British woman to achieve the feat in 39 years.
She also made the last four at the 2016 Australian Open and the 2019 French Open, while her best result at the US Open was a quarter-final run in 2019.
She made the announcement on social media, saying she was "grateful" for the career she had had.
Born to Hungarian parents in Australia before moving to the UK aged 14, Konta switched allegiance in 2012 and went on to become the most successful British female player of her generation.
