The Grand Knockout Tournament (colloquially also known as It's a Royal Knockout) was a one-off charity event which was shown on British television on 19 June 1987. It followed the format of It's a Knockout, a slapstick TV gameshow which was broadcast in the UK until 1982. The event was staged on the lakeside lawn of the Alton Towers stately home-cum-theme park.
