Kevin Pietersen has resigned as England captain and Peter Moores has stepped down as team coach after their working relationship broke down, a local news agency reported on Wednesday. South African-born Pietersen had questioned Moores' ability as a top international coach in a dispute which became public. Officials had been keen to have the dispute between the duo resolved before the England squad travelled to the Caribbean on January 21 for their four-Test tour of the West Indies. The England and Wales Cricket Board (ECB) were unable to confirm the report although they were expected to make a public comment later Wednesday.
