The Supermarket Sweep host passed away at the age of 62 at his home earlier on in the day, his agent confirmed in the evening. He also presented the National Lottery game show In It To Win It and the BBC series Hole In The Wall.
Tributes from Dale's many celebrity friends began to pour in.
His agent telling Press Association: "While we know many will share this awful loss, we ask that you respect the family's privacy at this time of grief".
Good Morning Britain host Piers Morgan, 53, added: "RIP Dale Winton, 62".
Presenter Hewson said: "So very sad about the gorgeous Dale Winton worked with him many times! Lovely man. Sad to hear the news".
Singer Boy George said he was "shocked", posting a message on Twitter saying Winton "was a sweet man".
Winton started his career as a DJ in London leading to work on local radio.
Ahead of the show airing, Winton told TV Times: "I've kept a low profile because I had about four surgeries".
Winton was a TV favourite with shows like Supermarket Sweep and In It To Win It. In June 2016 he revealed during an appearance on Loose Women that he had been suffering from depression following a hard relationship breakup.
Appearing on ITV chat show Loose Women, Winton said: "I did not want to put one foot in front of the other outside the house". Thanks for letting me go Wild In Your Aisles.
Just days after he turned 21, Winton discovered his mother, whom he adored, had died after taking an overdose.
Earlier this year he was back on TV, hosting Dale Winton's Florida Fly Drive on Channel 5.
