Harry Redknapp has signed a one-year contract to stay on in his role as manager of Birmingham City, the club have announced.
Redknapp, 70, guided Birmingham to safety in the Sky Bet Championship after taking over from Gianfranco Zola on April 18.
The former West Ham, Tottenham and QPR boss led the Blues to two wins in their final three matches as they avoided relegation by two points.
Redknapp agreed terms with Birmingham on Thursday night and the club announced his appointment on their official website.
"Just days after memorably guiding Blues to Sky Bet Championship safety, Redknapp has now committed again to the club," a statement read.
"Initially he came in on a short-term agreement as Gianfranco Zola's replacement for the final three matches of the season with Blues in a precarious position.
"But two wins from the final two games, culminating in that tense afternoon at Bristol City on Sunday, secured Blues a 19th place finish in the table.
"Redknapp held talks with the club's owners and board of directors this week and finalised the details of his contract (on Thursday) night.
"The composition of Redknapp's backroom team will be revealed in due course via bcfc.com."
Redknapp will be working alongside director of football Jeff Vetere, whose appointment by owners Trillion Trophy Asia was confirmed on Wednesday.
Steve Cotterill and Paul Groves are expected to remain as part of his backroom staff.
Zola ended his four-month spell as manager by resigning on April 17 following just two wins in his 24 games in charge, leaving Birmingham 20th in the table and three points above the relegation places.
Redknapp stepped in the following day and kept the club in the Championship when they won 1-0 at Bristol City in their final match.
Birmingham are expected to have cash to spend in the summer, even after Zola spent around £10million on new signings in January.
The Italian had replaced Gary Rowett in December after the latter had guided the club to seventh place.
