The all-rounder, 32, missed the 3-0 one-day series defeat in New Zealand in February with a broken finger.

He has played only one of Sunrisers Hyderabad's seven games in this season's IPL, on 24 March.

"Our camp is beginning," said Bangladesh cricket board president Nazmul Hassan.

"I have asked to send a letter to Shakib immediately to come back. Let's see how he responds to this."

Shakib, the second highest ranked all-rounder in Test, one-day and Twenty20 cricket, has scored 5,577 runs an average of 35.07 and taken 247 wickets at 29.68 apiece in 195 one-day internationals.

He has been named vice-captain of a squad that will be led by Mashrafe Mortaza.

The World Cup, in England and Wales, will run from 30 May to 14 July.
