TV and radio presenter Dale Winton has died at the age of 62.
The former Supermarket Sweep host died at his home earlier on Wednesday, his long-term agent Jan Kennedy said.
Winton spent nearly a decade hosting the ITV daytime hit but also hosted the BBC's lottery show In It To Win It and appeared in game show Hole In The Wall.
Friend and fellow TV presenter Davina McCall described him as a "lovely, warm, kind, sensitive, generous soul with a touch of naughty!"
Comedian David Walliams said he was "heartbroken" to hear of the death of his friend.
Winton's agent did not give details on the cause of death but said: "While we know many will share this terrible loss, we ask that you respect the family's privacy at this time of grief."
Kate Phillips, controller entertainment commissioning at the BBC, said Winton was "an immensely well-loved individual" and praised his "wonderfully unique and special energy" that he brought to TV programmes.
"He was extremely kind, brilliantly funny and was a true gentleman," she said.
Winton started his career as a DJ in London leading to work on local radio.
In 1986 he joined BBC Bristol to present Pet Watch for BBC One.
But his big break came with ITV's daytime show Supermarket Sweep, which he hosted from 1993 to 2001 and again when it was rebooted in 2007. Contestants on the show were tasked with running round a supermarket collecting items to win a cash prize.
He went on to work on prime-time shows including the National Lottery's In It To Win It and he hosted his own Christmas specials and celebrity guest shows.
More recently Winton, who was known for his tanned appearance, made a show for Channel 5 called Dale Winton's Florida Fly Drive. Channel 5 said the final episodes were due to air in June.
In an interview with the Times in 2008, Winton spoke about coming out as gay at the age of 47.
He said he had not come out before because no-one had ever asked him.
Winton also told the paper that he would stay up every night until the early hours, writing material ahead of his then new BBC show Hole in the Wall.
"I've always been a grafter," he said.
Winton was born in Marylebone, London in 1955. His mother, Sheree, who was an actress, died from an overdose shortly after his 21st birthday.
He told ITV's Loose Women show in 2016 about his struggle with depression and said: "I always thought, 'Get over yourself.' But my mum died of it. It exists and anybody out there who has had it knows it exists. I didn't want to put one foot in front of the other but for a couple of really good friends."
One of the friends his named on the show as supporting him was Walliams, with Winton saying "he has kept me going".
Other friends and celebrity colleagues have paid tribute to the TV star on social media.
Singer and friend Boy George - who appeared on Winton's episode of This is Your Life in 2000 - said he was "shocked" to hear of the death and described Winton as "a sweet man".
