Middlesex will start their Vitality Blast campaign with a home match against Surrey at Lord's on Thursday June 10.

The tournament returns to a 14-match group stage format with the first-class counties split into traditional North and South groups.

And Vitality Blast Finals Day will be staged at Edgbaston on September 18, with all fixtures available on BBC Local Radio stations, with extensive coverage also on 5 Live Sports Extra.

The Royal London Cup will return this summer, after a hiatus in 2020 due to the Covid-19 pandemic, with the final at Trent Bridge on August 19.

Middlesex begin that 50-over competition at Berkshire on July 20, then visit Essex five days later.

ECB Managing Director of County Cricket, Neil Snowball, said: “The stage is set for an exciting and important summer of domestic cricket for the First-Class Counties and the women’s regional teams.

“I know how much county members and supporters eagerly anticipate the release of fixtures and I am pleased that we have been able to plan a complete schedule for men’s and women’s cricket.

“The Vitality Blast has established itself as a much-loved tournament while the return of the Royal London Cup, alongside the remodelled County Championship for this season, will be warmly welcomed as we all look forward to the summer.

“I am also delighted that we will shortly release the schedule for the women’s Regional 50 over and T20 competitions. These competitions will not only showcase the deepening pool of talent in women’s cricket, but also further strengthen the professional pathway for our female players.”

The health and safety of anyone attending matches this summer will remain the priority of the ECB and the First-Class Counties.

The ECB continues to work closely with Government, and other sports, as it plans ways to safely welcome supporters back to venues across England and Wales this summer.

Women’s domestic cricket is set for a memorable summer with the staging of the Regional 50 over and T20 competitions in addition to the launch of The Hundred.

Forty-one female players have signed professional domestic contracts ahead of the summer to further establish the elite pathway for female cricketers.
