Irish comedian Sean Hughes has died at the age of 51, a representative has confirmed.
The comic, who rose to fame with the sitcom Sean's Show in the 1990s, was reported to have died in hospital on Monday.
He was an original panellist on Never Mind The Buzzcocks alongside Mark Lamarr and Phill Jupitus.
He also had a small part in The Commitments film, and in 1990 was the youngest comic to win the coveted Perrier comedy award.
His last post on social media, earlier this week, said he was "in hospital".
Comedians and writers shared tributes to Hughes online, many reflecting on friendships with the comic.
Actor and stand-up Aisling Bea wrote that Hughes was a "wonderfully silly, anarchic & hilarious comic" and said she "enjoyed the mad tangents our conversations would take".
Writer Irvine Welsh described him as a "witty, gracious, kind and gentle soul", while Classic FM presenter Andrew Collins said he was an "absolute angel".
Kate Phillips, controller of entertainment commissioning at the BBC, said she was a "huge fan" of the comedian.
"There is no doubt that Sean's unique wit, dry delivery and ability to engage and have fun with guests week in week out helped establish Never Mind The Buzzcocks as one of the most memorable panel shows of all time," she said.
In addition to comedy Hughes acted in several West End theatre productions and wrote two novels.
Tributes have been pouring in online for the actor since his death overnight.
So sad about Sean Hughes. Such an engagingly funny man.
