Ace all-rounder Shakib Al Hasan has been officially named captain of the Twenty20 team, Bangladesh Cricket Board (BCB) president Nazmul Hassan announced.

"Since Mashrafe has retired, the board unanimously agreed to appoint Shakib as Bangladesh's next captain for Twenty20 internationals," BCB president Nazmul Hasan told reporters after the meeting.

"A few other names were discussed but in the end we all have agreed to appoint Shakib," he said.

Shakib has captained the T20 side on four previous occasions, with the Tigers suffering losses in each of those.

With the announcement, Bangladesh now have three captains for three formats. Mashrafe announced his retirement from the shortest format of the game in the recently-concluded tour of Sri Lanka, leaving the position vacant.
