Waqar Younis has announced his resignation as Pakistan coach, citing personal reasons.
Waqar, who took charge in March 2010, will continue in the job until the end of the forthcoming tour of Zimbabwe.
"I have tendered my resignation to the board last week and the tour to Zimbabwe will be my last," Waqar said.
"I have taken this decision on personal grounds, including medical grounds, and have no differences with anyone. My resignation has been accepted."
The 39-year-old former fast bowler's spell as coach has come at a difficult time for Pakistan.
Three players were been banned over a spot-fixing scandal during the tour of England in 2010 and there was a falling out with former one-day captain Shahid Afridi.
Pakistan play one practice game, one Test, three one-day internationals and two Twenty20 matches on the tour of Zimbabwe, which starts on 28 August.
