Alex Hales has put his England future in jeopardy after disappointing director Andrew Strauss with his decision to pull out of the upcoming tour of Bangladesh.

The former Chesham Grammar School pupil joined ODI captain Eoin Morgan in withdrawing from the squad over fears about security.

After learning his trade in the Bucks cricket leagues, Hales has gone on to establish himself in both England’s test and ODI sides.

The 27-year-old smashed England’s highest ever ODI score of 171 at Trent Bridge just last month, but has done himself no favours with selectors by pulling out.

Strauss said: "While we understand and respect Eoin and Alex's decision, we are disappointed that they have made themselves unavailable for selection for the Bangladesh tour."

Jos Butler will replace Morgan as captain and it is likely both players’ places will come under pressure during the tour.

The series, which will include three ODIs under Buttler's leadership and two Tests under Alastair Cook, was given the go-ahead following an ECB security review.

Concerns had been raised about the safety of the trip after the July terror attack in a Dhaka cafe which resulted in the loss of 29 lives.

Former England captain, Michael Vaughan, was shocked by the pair's decision and described it as a "huge mistake", particularly on the part of Morgan.

Hales' unavailability means he will miss both legs of the tour and almost certainly five Tests which immediately follow in India before Christmas. His selection in the longer format was far from guaranteed in any case.

Strauss sought assurances from all those in line for selection that they were prepared to travel during annual appraisals on Friday and Saturday in Loughborough for all players with central or increment contracts.

"We have had open and honest conversations with all the players about the security arrangements in Bangladesh - and at this stage we are not expecting any other individuals to withdraw from the tour," Strauss said.

"Final selection for the Bangladesh tour will now take place on Friday.

"As with all England overseas tours, the safety and security of players and staff is of the utmost importance to ECB. We will continue to monitor the situation in Bangladesh, take advice and consider the appropriate steps up to and throughout the five weeks we are on tour."

All-rounder Ben Stokes posted a statement on Twitter in which he said he respected the decisions of his team-mates.

"I will always back, not just my captain but also any fellow team-mate's decision on matters like this," Stokes wrote.

"They have both obviously thought long and hard about this important decision and have both made the call that is right for them as individuals.

"Please try and respect their choice, I do, as a colleague and as friend to them both."

England confirmed last month that the trip could go ahead, only after security expert Reg Dickason returned from a fact-finding mission with a favourable briefing.

Morgan spelled out his concerns last week, citing his previous experience of security alerts in India and Bangladesh.

The Irishman added he has long promised himself he would never revisit a situation in which such problems prevented him giving cricket his full concentration.

For England, time is short to pick the right men to fill the gaps left in their powerhouse ODI batting line-up.

The uncapped Ben Duckett is an obvious option after his prolific season across the formats for Northamptonshire, as is a return to the first-choice team for Jonny Bairstow - but who opens alongside Jason Roy in place of the record-breaking Hales is a difficult call.
