Magician Paul Daniels has died, his publicist has confirmed.
The 77-year-old was diagnosed with an "incurable brain tumour" last month after a fall at his home.
For 20 years he was among the most well-known entertainers in Britain, along with his glamorous assistant and later wife Debbe McGee - who has family that hail from Northern Ireland.
He presented his popular Paul Daniels Magic Show on the BBC for 15 years and was known for a string of catchphrases, including the line: "You'll like this... not a lot, but you'll like it."
In a statement, Daniels' agent said he had died in his sleep in the early hours of Thursday morning, "at home with Debbie at his side".
"Debbie and the family would like to thank everyone for their support and asks that their privacy be respected at this sad time," the statement read.
Born Newton Edwards Daniels in Middlesbrough in 1938, Daniels later said he became interested in magic as a young child - but only turned professional in 1969 with a summer season in Newquay.
The following year Daniels came second in talent show Opportunity Knocks, which led to him being offered a regular slot on the ITV variety show The Wheeltappers and Shunters Social Club.
In addition to performing magic, Daniels hosted popular quiz shows for the BBC including Every Second Counts, Odd One Out and Wipeout.
In later years Daniels and McGee participated in various TV shows including Channel 5's The Farm, The X Factor: Battle Of The Stars and Celebrity Wife Swap.
He leaves wife Debbie McGee and his three sons from a previous marriage.
