Defender Robert Huth has completed a permanent move to Leicester after a successful loan spell last season.
The 30-year-old Germany international, who played a key role in the Foxes' successful Barclays Premier League survival charge at the end of the campaign, has signed a three-year deal after the club agreed an undisclosed fee with Stoke.
He becomes manager Nigel Pearson's second summer signing following the arrival of Austria defender Christian Fuchs from Schalke earlier this month.
Huth took to his Twitter account to express his delight at the move minutes after the official announcement.
He tweeted: "STOKE YOU HAVE BEEN SENSATIONAL!!! Thanks for everything, I'll never forget it! Now the sexy football show rolls into Leicester!!"
The Berliner, whose move is understood to have cost the Foxes around £3million, headed for the King Power Stadium in February and made 14 appearances as Leicester dragged themselves from the brink of relegation to the relative comfort of 14th place.
They lost only four of the games in which he played, with he, Wes Morgan and Marcin Wasilewski providing a sizeable barrier in front of keeper Kasper Schmeichel with City keeping five clean sheets in their final nine games, a run from which they claimed 22 of a possible 27 points.
Huth began his professional career at Chelsea, where he won two Premier League titles, before limited opportunities prompted him to head for Middlesbrough in 2006.
Boro's relegation at the end of the 2008-09 season saw him switch to Stoke, where he established himself as a regular at the heart of Tony Pulis' combative rearguard, and he now has more than 250 Premier League appearances under his belt.
His transfer was completed on a day when it emerged that Leicester also have an interest in Potters' midfielder Steven Nzonzi.
Indeed, reports on Wednesday suggested they had tabled a £7million bid for the Frenchman, although neither club confirmed or denied the claims.
