Naomi Dattani joins Knight and Deandra Dottin in remaining with the side for 2021 as the squads continue to take shape
First 18 players confirmed for The Hundred 2021
London Spirit will be captained by England skipper Heather Knight when The Hundred gets underway in 2021.
The 29-year-old, who was pencilled in for the role this year, keeps hold of the position for the inaugural edition of the competition next summer
Sunrisers' Naomi Dattani has also agreed to remain with the Lord's based side.
West Indies batter Deandra Dottin had already signed up to return as a marquee player.
All-female players have the option to roll-over their contracts on the same terms for next year after the launch was delayed due to the Covid-19 pandemic.
"It is a real honour to be retained as skipper for next year," said Knight, who has led England since 2016, a spell which includes a World Cup win. "We are beginning to build an exciting side and hopefully we can make a real impact on the pitch.
"While it was obviously disappointing that the competition wasn’t able to take place this year, The Hundred promises to be a real leap forward for our sport and I can’t wait to lead the side in 2021."
Dattani added: "It’s really exciting to compete in The Hundred next year. The competition will be a big step forward for the women's game, offering the opportunity for professional women’s cricket to be presented on the same platform, and with equal billing, alongside the men’s game."
