Renowned broadcaster Sir Terry Wogan has died aged 77 after a short illness, the BBC has said.

The Irish-born presenter was best known for his roles hosting chat show Wogan, the Eurovision Song Contest and the Children in Need fundraisers.

Sir Terry retired from his hugely popular BBC Radio 2 Show Wake Up to Wogan in 2009.

BBC Director General Tony Hall said Sir Terry Wogan "truly was a national treasure", adding: "Today we've lost a wonderful friend."
