England captain Eoin Morgan has accused disgraced Alex Hales of “complete disregard” for team values following the Nottinghamshire batsman’s exile from the tournament hosts ‘ ICC World Cup squad.

Hales was dropped from all England squads, including the provisional 15-man party for the World Cup, after reportedly failing a second test for recreational drugs, a move Morgan said was supported by the team’s senior players.

But England only decided to send Hales into international exile after a report of a 21-day ban from cricket was published in the Guardian newspaper.

The England and Wales Cricket Board insisted they could not go public with details of Hales’s suspension because of their own rules regarding the handling of drugs offences, meaning Morgan, selection chief Ed Smith and coach Trevor Bayliss were unaware of any problems when England named their provisional squad last month.

Morgan, speaking ahead of England’s season-opening one-day international away to Ireland on Friday, did not pull any punches when asked about Hales’s conduct.

“Unfortunately Alex’s actions have shown complete disregard for those [team] values,” Morgan told reporters in Malahide on Thursday. “This has created a lack of trust between Alex and the team.

“On Saturday, we got together as a group of senior players to discuss the effect the news coming out would have on the team and the culture. We all agreed the best decision for the team was for Alex to be deselected. I relayed this to Ashley Giles, because we don’t have final say, I can only give the view in the changing room and how guys feel. I think we’ve dealt with it really well.”

England are determined to avoid off-field distractions and controversies as they bid to win the men’s 50-over World Cup for the first time.

They have adopted an increasingly hardline approach as a direct response to a late-night incident in Bristol, where Hales was present, that eventually saw Ben Stokes cleared on a charge of affray but miss the 2017/18 Ashes tour of Australia.

“We’ve worked extremely hard on our culture in the last 18 months since the Bristol incident,” said Morgan, who contacted Hales to offer support when, before the Guardian story broke, it was announced he was taking a break from Nottinghamshire duty for “personal reasons”.

“When the news broke the day before we met in Cardiff [for an England training camp], it left me to think about how this would affect the team and the culture in particular,” he explained. “We will need at least 15 men to win the World Cup and, whatever way Alex would have dealt with it, the other 14 people would have been dragged down and that would have been quite a weight taken forward.”

Hales is set to make his Nottinghamshire comeback on Friday after being named in a squad for a One-Day Cup match against Durham.
