British television and radio personality Terry Wogan died of cancer aged 77 on Sunday (local time), his family said.
Irish-born Wogan, one of the BBC's most recognizable faces and voices, was granted a British knighthood in 2005.
"Sir Terry Wogan died today after a short but brave battle with cancer. He passed away surrounded by his family," a statement on behalf of his family said.
Wogan began his broadcasting career with Irish state broadcaster RTE before joining the BBC in 1966. He went on to become a national institution as a disc jockey, chat show host and presenter, known for his gently mocking wit and Irish brogue.
He hosted the BBC's coverage of the Eurovision Song Contest from 1980 to 2008.
