Broadcaster Sandi Toksvig has paid tribute to “lovely” 15 to 1 host William G Stewart, calling him a “consummate TV professional”.
The Bake Off host added it was “sad news” to hear of his death on Thursday.
Stewart, who was 84, was 15 to 1’s host from 1988 to 2003, with Toksvig taking over in 2014.
Channel 4 was “saddened” by the news, saying the “broadcasting legend” had “inimitable style” which “set 15 to 1 apart from all other quiz shows”.
“Our thoughts are with his friends and family” the broadcaster added.
Comedian Adam Hills, who hosts the Celebrity Fifteen To One series which first screened in 2013, raised a fond smile with his tweet, saying: “Even if I had three feet, I’d never have filled his shoes.”
Another longstanding Channel 4 quiz show, Countdown, also paid tribute, calling Stewart “our C4 brother of old”.
Stewart, who died after a brief illness, made 2,265 episodes, met almost 34,000 contestants and presented at least 350,000 questions.
