New Zealand’s team, which includes three-times Olympian single sculler Emma Twigg, numbers 32, while Canada will send 29 rowers and Ireland have named a team of 13 including Sanita Puspure, the 39-year-old Latvian-born single sculler who won world gold in 2018 and 2019.

Glover, 35, won Olympic women’s pairs gold at the London 2012 and Rio 2016 Games with Heather Stanning, after which she retired and became a mother of three children.

Glover, one of 24 women in the British team, said: "This is the thing I was aiming for when I first came back.

"I genuinely thought it was an impossible mission this time last year but I always had this day in my sights and I feel really proud that it’s here and that I’ve made the Olympic team."

Moe Sbihi, who earned bronze in the men’s eight at the London 2012 Olympics and was in the gold-medal winning coxless four at Rio 2016, will return as part of a men’s eight including eight Olympic debutants, including coxswain Henry Fieldman.

Also returning for a third Olympics will be Vicky Thornley, who won silver in the women’s double sculls at Rio 2016 with 40-year-old London 2012 gold medallist Katherine Grainger and will compete in the single sculls in Tokyo.

Meanwhile the task of maintaining a British gold medal sequence in the men’s coxless four that goes back to Sydney 2000 rests with Ollie Cook, Matt Rossiter, Rory Gibbs and Sholto Carnegie, who have recently won the European title and the World Rowing Cup II.

The 38-strong Australian team features 29 debutants, eight athletes returning for their second Olympics and one, Joshua Booth, being named for a third Games.

Booth is one of three Rio 2016 Olympic silver medallists along with Alexander Hill, who was with him in the men’s four, and men’s quadruple sculls member Cameron Girdlestone.

Nick and Alexander Purnell become the first brothers on the Australian Olympic rowing team since 2004, while debutant Rosie Popa continues her family’s Olympic legacy, with parents Sue Chapman-Popa and Ion Popa medallists for Australia at Los Angeles 1984.

Georgie Rowe, who set multiple indoor rowing world records in 2019 and 2020, makes her Olympic debut just four years after taking up the sport, having transitioned from surf boats to rowing in 2017.

Meanwhile women’s eight team member Olympia Aldersey has achieved what appeared to be her destiny, her parents having chosen her name because she was born on the opening night of the Barcelona 1992 Olympics.

Of the 37 United States athletes there are 11 returning Olympians with six Olympic medals amongst them.

Megan Kalmoe, a London 2012 bronze medallist in the women’s quadruple sculls, will be competing in her fourth Games, while Meghan Musnicki, Gevvie Stone and Ellen Tomek will be at their third Olympics.

Musnicki was in the women’s eight that took gold at Rio 2016 along with Katelin Guregian, who will be making her second Olympic appearance.

Stone was the other US medallist in Rio, taking silver in the women’s single sculls.

Among her opponents in Tokyo will be New Zealand’s 2019 world silver medallist Emma Twigg, making her fourth Olympic appearance and seeking to improve upon the tantalising fourth place she achieved at the last two Games.

The New Zealand team includes the 2019 world champion women’s eight and women’s pair teams.

Canada has selected its largest rowing team since the 1996 Atlanta Games, where rower and sculler Marnie McBean, Team Canada’s Chef de Mission in Tokyo, became the first Canadian to win three Olympic golds in company with the late Kathleen Heddle.

Caileigh Filmer and Hillary Janssens won the world women’s pair title in 2018 and added a bronze in 2019.

Will Crothers, a member of the men’s eight who won silver at London 2012 Olympic Games. will sit in the stroke seat of the men’s four, a new crew combination who recently qualified the boat for Tokyo at the Final Olympic Qualifier in Lucerne.

Team Ireland’s selection, its largest ever in rowing, includes Puspure and Paul O’Donovan, who won silver at the Rio 2016 Games with his brother Gary in the lightweight double sculls, and will contest the same event in company with new partner Fintan McCarthy.

Olympic rowing in Tokyo is due to start on July 23 and run until July 30 at the specially constructed Sea Forest Waterway.
