Cameron Norrie, Dan Evans and Katie Boulter will all be part of the Great Britain team for the 2024 United Cup.

Men’s world number one Novak Djokovic and women’s world number two Iga Swiatek have also entered.

The United States won the inaugural tournament, which was played in January.

Nine of the world’s top 20 men and five of the world’s top 10 women will feature including Alexander Zverev, Casper Ruud, Wimbledon winner Marketa Vondrousova and former world number one Angelique Kerber, who could be making her first appearance since having a baby.

Great Britain will enter the competition, beginning on 29 December and ending on 7 January 2024, as one of the top seeded teams.

At the last tournament the British team reached the quarter-finals but were knocked out by eventual winners the USA.

Countries will be drawn into six groups of three countries and will compete in a round-robin format in teams made up of up to three men and three women.

Each city will host three groups of three countries with the group winners plus the best runners-up from each city advancing to the quarter-finals.

Unlike the last tournament, each session will include one men’s singles and one women’s singles match featuring each team’s top-ranked singles players, followed by one mixed doubles match with a result determined in one session.
