Nottinghamshire captain
Steven Mullaney will lead England Lions in their triangular series against India A and West Indies A later this month.
The squad features five players capped by England - Liam Livingstone, Sam Curran, Liam Dawson, Craig Overton and
Reece Topley - and also Ben Foakes who was part of the Test squad throughout the tour of Australia and New Zealand.
Matt Parkinson, the Lancashire legspinner who has impressed this season with red and white ball, is included - he is the leading wicket-taker in the Royal London Cup with 18 wickets at 18.22.
Topley's inclusion is significant encouragement for the left-armer who has played 10 ODIs and six T20Is for England. He has suffered a succession of lower-back injuries and has opted to focus on white-ball cricket in 2018.
Joe Clarke, the Worcestershire batsman, has not been included with a decision to allow him to play red-ball cricket. The tri-series coincides with two rounds of the County Championship - Worcestershire play Lancashire and Nottinghamshire during that period - and pulling players out for Lions duty has caused tensions in the past.
