Gary Lineker: BBC Match of the Day host to leave at end of season - BBC News
So according to the BBC themselves, Lineker would leave Match of the Day's usual highlights show at the end of the season but stay on as an FA Cup presenter for 25/26 and the 2026 World Cup, then leave.
For all that I know a few will bring his outspoken politics into this, by the end of that World Cup he'll be 65 having been a BBC broadcaster for nearly 30 years. If there's a mutual agreement now is the time for retirement, think he's earned it tbh.
