Birmingham have announced that manager Alex McLeish has signed a new three-year contract.
McLeish, 51, joined Birmingham in 2007 following a brief but impressive spell in charge of the Scottish national team.
The Blues suffered relegation to the Championship in his first season, but he took them back to the Premier League at the first attempt and then secured a ninth-place finish in the top-flight - their best for over 50 years.
A statement on the club's official website read: "Alex McLeish has put pen to paper on a new three-year contract, keeping him at St Andrew's until the summer of 2013.
"Club president Carson Yeung has rewarded that success with a new improved deal for McLeish, after giving the green light for him to bring in Ben Foster, Nikola Zigic, Enric Valles, Matt Derbyshire, Alexander Hleb, Martin Jiranek and Jean Beausejour in the August transfer window. That followed the acquisitions of Craig Gardner and Michel in January."
The announcement comes on the same day football consultant Sammy Yu announced his departure.
"I think the time is right for me to step down," he told the Birmingham Mail. "After four years being part of the whole deal, from the beginning, I have done my bit.
"It's time to release myself and I wish Birmingham City the best for the future. To be part of the club's history in a very important era is a highlight of my life."
