King is the longest serving player at the King Power Stadium, joining the Foxes as a youngster. He has played for the club in League 1 and the Championship before lifting the Premier League trophy last season.
He is the first player in English football history to win the top 3 domestic divisions with the same club.
The new deal will keep the Welshman at the club until 2020, with the Foxes keen to keep their players at the club. N’Golo Kante has joined Chelsea, but they were able to hold onto Jamie Vardy, who snubbed a move to Arsenal in order to stay with Claudio Ranieri’s side.
King played in 25 league games last season, scoring twice, before featuring in 3 of Wales’ EURO 2016 games. The 27-year-old played in both the knockout win over Belgium and their semi-final defeat Portugal.
And now the midfielder has a season of UEFA Champions League football to look forward to, with the group stage draw to be made on August 25th.
