Next year's county season will encompass just three competitions, the England and Wales Cricket Board have announced.

There will still be the LV County Championship, an enhanced Twenty20 tournament to be played in June and July, but only a single one-day competition, to be played on Sundays.

ECB chairman Giles Clarke said: "We canvassed a wide range of opinion and everyone was behind the principle of the primacy of Test match and County Championship cricket.

"It is important that the County Championship structure is maintained to support the England Test team.

"We have also listened to the spectators and counties alike about the structure and the consensus was for Twenty20 cricket to be played in June and July with a final later in the season with the qualification matches primarily at weekends."

The new Twenty20 tournament, called the P20, will be split into a north and south pool, with exact regulations yet to be decided.

Adminstrators are also exploring different options for the new Sunday League, which may still be a 40-over format.

Intriguingly, the ECB have floated the idea of each team playing two innings of twenty overs, without restrictions on bowlers.

Meanwhile both Twenty20 Cup quarter finals were called off for rain last night. Lancashire and Somerset, and Hampshire and Northants, will try again tonight.
