Who is the women's British No. 1 tennis player?
Katie Boulter is currently the British No. 1, becoming the 23rd woman to do so since the rankings began in 1975.
The Leicester-born player rose to the summit by reaching the semifinals of the Lexus Surbiton Trophy in June 2023, then entered the world top 100 for the first time since 2019 by winning her first WTA title at the Nottingham Open
Now ranked 77, Boulter began 2023 by winning the seventh ITF title of her career at the W60 Canberra event, only dropping a set for the first time in the final.
The 26-year-old has not qualified for the main draw of a grand slam since reaching the third round of Wimbledon in 2022.
After beating sixth seed and former world number one Karolina Plískova in the second round, Boulter won two games in a straight sets defeat to current world number 282 Harmony Tan.
Boulter has been given a wildcard for Wimbledon, which is given to players whose ranking is not high enough to secure automatic entry. Wildcards are awarded on the basis of past performance or to increase home interest.
British number two Jodie Burrage, four Harriet Dart, five Katie Swan and six Heather Watson have also received wildcards. Number three Emma Raducanu — the 2021 US Open winner — is out through injury.
