The One-Day Cup is a 50-over competition played by the 18 first-class counties across England and Wales and returns again this month.
The tournament was first played in 2014 and takes place annually between the start of August and the middle of September.
Leicestershire are the current holders after winning their first title in 2023.
The One-Day Cup is a 50-over round-robin competition featuring the 18 first-class counties who also contest the four-day County Championship, and begins this year on 24th July.
It was first played in 2014, replacing the ECB 40, which saw each team allocated a 40-over innings per match. The organisers increased the number of overs to 50 to bring it in line with one-day internationals.
The quarter-finals are due to take place on 16th August, the semis will be staged on 18th August and the final will take place the following month, on 22nd September.
In the group stage, games get underway at 11.00 BST. Then in the knockouts, the quarter-finals and semis will be day-night matches, starting at 15.30 BST.
The final is due to start at 11.00 BST.
The 18 county teams are split evenly into two groups, with nine in Group A and nine in Group B.
Lancashire, Worcestershire, Kent, Middlesex, Durham, Hampshire, Northamptonshire, Somerset and Derbyshire will all compete in Group A.
Group B comprises Essex, Leicestershire, Warwickshire, Surrey, Glamorgan, Nottinghamshire, Yorkshire, Gloucestershire and Sussex
The matches in the One-Day Cup will be played at various cricket grounds across the UK, including some at the County team's traditional homes, like Old Trafford, Edgbaston and Trent Bridge.
Other smaller venues, like the St Lawrence Ground in Canterbury, Radlett Cricket Club in Radlett and Stanley Park in Blackpool will also stage some matches.
Selected games from the One-Day Cup will be broadcast on Sky Sports Cricket.
Since the competition began in 2014, there have been nine different One-Day Cup winners. Durham triumphed in the first iteration 10 years ago, followed by Gloucestershire, Warwickshire, Nottinghamshire, Hamshire and Somerset.
Glamorgan were the victors in 2021, Kent won in 2022 and Leicestershire were crowned One-Day Cup champions for the first time in 2023 when they beat Hampshire in a dramatic final at Trent Bridge.
Batting first, the Foxes scored 267-7 from their 50 overs, with Harry Swindells scoring an unbeaten century. Hants were on course to chase down their target at the midway point of their innings, but an inspired fightback from Leicestershire's bowlers saw the Foxes triumph by just two runs off the final ball of the match.
Each group winner progresses straight to the semi-finals, while the teams who finish second and third advance to the quarter-finals, with the runner-up in Group A hosting third in Group B and vice-versa.
The victors then face the two group winners before the winners of each semi-final go on to play in the final.
