Details of a 100-ball format for the new white-ball competition in England and Wales have been agreed, the ECB has confirmed.

English cricket's governing body prompted a somewhat mixed reaction last April when they revealed plans for their new domestic tournament to feature innings of 100 balls a side.

However, in a media release on Thursday, the ECB confirmed the first-class counties of England and Wales have voted overwhelmingly in favour of their proposed playing conditions for an event that will now officially be known as The Hundred.

The new competition will feature changes of ends after 10 balls and 25-delivery powerplays for each team. Bowlers will be able to deliver either five or 10 consecutive balls and a maximum of 20 deliveries per game.

"This is a significant step, with overwhelming support for The Hundred," said ECB chief executive officer Tom Harrison after 17 of the 18 counties voted in favour.

Sanjay Patel, who will take up the role of managing director for the new competition, added: "This agreement for the playing conditions shows the confidence that the counties have in the new competition and their desire to help take cricket to more people.

"You will now see an acceleration in the progress of The Hundred and a series of significant building blocks over the coming months, before our first ever player draft in the autumn.

"The next major step will be to confirm the team identities, with their names and kit colours, following months of research and consultation and, operationally, the new competition team will be able to move into the next phase of developing The Hundred."
