Emma Raducanu is ready to "embrace her position" as leader of a new-look Great Britain team when they face the Czech Republic in the Billie Jean King Cup, says captain Anne Keothavong.
US Open champion Raducanu, 19, assumes the role in a young squad which, for the first time since 2010, is without either Johanna Konta or Heather Watson.
Raducanu is joined by Harriet Dart, Katie Swan and Sonay Kartal.
"It feels like a new era. I'm excited about the team," said Keothavong.
World number 12 Raducanu is the highest-ranked player in the British team - and the highest-profile - after her swift rise to becoming a Grand Slam champion in New York last September.
