Daily Mail Sport can reveal that the initial draft of the 2027 domestic schedule includes two rounds of matches in both June and July.

Such a framework would provide players coming back from injury or squad members missing out on selection in England XIs access to four-day action both in the build-up and during the five matches.

County chiefs have also pushed for the Championship to be more evenly spread across the six months of the domestic season in a bid to keep members - increasingly agitated by the domination of the Hundred during peak summertime - happy.

This has been done by removing two of the six rounds that run from 20 August this year and re-positioning them in July.

If the original draft is approved, the 2027 season will feature the County Championship’s earliest ever start of 2 April, beginning with seven rounds of matches, punctuated by three-day gaps. Each team will be given one week off during this initial block.

Twenty20 finals day at Edgbaston is to remain in July, the slot it was shifted to for 2026. (Confirmed for Saturday 17 July, https://www.edgbaston.com/media-article/date-confirmed-for-2027-vitality-blast-finals-day-at-edgblaston)
