England have named four uncapped players in their provisional squad for the ICC Champions Trophy in June.

Middlesex's new seamer James Harris, Yorkshire batsman Gary Ballance, Warwickshire bowler Chris Wright and Bears opener Varun Chopra have been added to the 30-man squad.

While new faces have been placed into the provisional squad, there is no position for wicketkeeper-batsman Matt Prior.

National Selector Geoff Miller said: "This is a balanced squad which will provide the selectors with strong options in all areas and reflects players' performances for both the senior England teams and the England Lions and EPP squads over the winter period.

"With this country hosting the tournament for the first time since 2004, there will be every incentive for England to perform well and we anticipate intense competition for places in our final squad which will be named early next month."

The final squad will be halved on May 5.
