England hand out three-year contracts to Wood, Root and Brook

England test captain Ben Stokes received a one-year deal, while his white-ball counterpart Jos Buttler was given a two-year contract.

"The system, which covers both red-ball and white-ball players, considers the likelihood of players featuring in England teams across formats over the next period while recognising performances in the preceding year," the ECB said in a statement.

"Multi-year contracts have been awarded for the first time since central contracts were established in 2000.

"The ECB has worked closely with the Professional Cricketers' Association and Team England Player Partnership on behalf of the players to reach an outcome for all parties."

Brook is among seven players to have been given a central contract for the first time along with Rehan Ahmed, Gus Atkinson, Brydon Carse, Ben Duckett, Matthew Potts and Josh Tongue - who have all got two-year contracts.

"We are rewarding those players who we expect to make a significant impact over the coming years playing for England," said Rob Key, managing director of England men's cricket.

"It is great news and a credit to the players for demonstrating their commitment to English cricket in the ever-changing landscape of the sport."

Batter Dawid Malan, who missed out on a full deal last year, was given a one-year contract off the back of his red-hot form in recent months, while veteran bowler James Anderson was also handed a one-year deal.

Matthew Fisher, John Turner and Saqib Mahmood have been given development contracts.

In 2021, England switched to a new system of central contracts which was a departure from the previous separation of red-ball and white-ball deals the ECB introduced in 2016.
