Peter Moores is set for a dramatic return as England head coach and will be unveiled on Saturday morning, Press Association Sport understands.

Andy Flower's replacement will be announced by Paul Downton, managing director of England cricket, at Lord's and it is understood that Moores is the chosen candidate.

The 51-year-old Lancashire coach previously held the job between 2007 and 2009, but was dismissed after disappointing on-field results and a damaging personality clash with then captain Kevin Pietersen, who was also deposed.

With Pietersen's international career now over, however controversially, the way is clear for Moores to return.

If Moores is, as expected, appointed to replace his own successor then current limited-overs coach Ashley Giles would appear to be out of a job.

The England and Wales Cricket Board's specification for the job made clear the successful applicant would be in charge of all three formats - Flower having advised the decision to split the role in two was unsuccessful.

Giles, the Ashes-winning spinner, was overwhelming favourite to edge out Moores, as well as the likes of Nottinghamshire's Mick Newell, Sussex's Mark Robinson and Australian Trevor Bayliss, until a below-par performance at the World Twenty20, and in particular a humiliating loss to associate nation Holland, saw his stock plummet.

It is unclear whether England's new assistant coach will be announced on Saturday, though a number of options have been discussed.

Flower's right-hand man Richard Halsall is not expected to be in the frame and is considering a return to teaching, but Robinson has been discussed as a number two and Sri Lanka's English head coach Paul Farbrace may also be interested despite winning the World T20 in Bangladesh.

The appointment of Moores would represent a gamble by the ECB, with his previous reign hardly a high water mark in recent years.

But he is a well respected figure in the domestic game and has impressed with his work at Lancashire, not least in 2011 when he won the Red Rose county's first outright championship since 1934.

While there were reports at the time that Pietersen was not the only senior player who was unimpressed with Moores' methods, he can also claim credit for the emergence on the international stage of Matt Prior, Graeme Swann and Stuart Broad.

He was also an important figure in restoring James Anderson to the Test side and England's senior bowler remains a firm fan.

England host Sri Lanka and India this summer, two potentially tricky assignments even on home turf. but the new coach's first task will be a one-day international against Scotland on May 9.
