England’s poor results and Cook’s loss of form led to the England and Wales Cricket Board to leave him out of the World Cup squad tonight.

The 29-year-old Cook had made just one 50 in his last 22 one-day international innings.

“I am gutted to be left out of the World Cup squad and it is likely to take me a while to get over the disappointment,” Cook said in an ECB statement. “That said I wish Peter, Eoin and the lads all the best for the World Cup.”

England’s full 15-man squad, initially for the tri-series against hosts Australia and India next month, was due to be announced later on Saturday local time.

England’s World Cup campaign starts against Australia in Melbourne on February 14.

“It is a huge honour to captain England and I am delighted to be leading the one-day side,” Morgan said.

“I firmly believe that with the players currently involved in the one-day set up we have the makings of a very good one-day side, a young side that can surprise people at the World Cup.”

ECB managing director Paul Downton said Cook remained an “integral part of England cricket and continues to have a vital role in developing our emerging test side”.
