Britain's four-time Paralympic Games medallist Jordanne Whiley has announced her retirement from wheelchair tennis aged 29.

At Tokyo 2020, Whiley reached the semi-finals of the women's singles competition, where she was beaten by the eventual winner and 12-time singles Grand Slam champion Diede de Groot of The Netherlands.

However, she secured a medal by beating de Groot's compatriot Aniek van Koot in the match for bronze.

Playing with Lucy Shuker, Whiley also earned a silver in the women's doubles in the Japanese capital.

This followed the pair securing bronze medals at London 2012 and Rio 2016.

Whiley is the country's most decorated player in the sport, making history at the US Open in 2015 as she beat Japan's Yui Kamiji to become the first Briton to win a women's singles wheelchair tennis Grand Slam.

She also won 12 doubles Grand Slams titles during her career, most recently with Kamiji in July as she triumphed at Wimbledon for the fifth time.

Those victories also included a calendar Grand Slam in 2014, as she won doubles titles at the Australian Open, French Open, Wimbledon and the US Open.

Whiley posted on Twitter that her 16-year professional career in wheelchair tennis had been "the biggest chapter of my life", and described her success at Tokyo 2020 as "the perfect ending".

"I have lifted many titles and received many honours, but nothing compares to the people I have shared it all with and the experiences I have had along the way," Whiley added.

"Although it feels weird to be leaving such a huge chapter of my life in the past, I know this is the right time to move on to other great things."
