Singer-songwriter Lynsey de Paul, who had five top 20 hits and represented the United Kingdom at the Eurovision Song Contest, has died aged 64.
The star, whose biggest hit Sugar Me got to number five in the singles chart in 1972 just a year after she launched her music career, died in hospital on Wednesday, her agent confirmed.
She had complained of severe headaches and it is understood she may have suffered a brain haemorrhage.
De Paul teamed up with Mike Moran as the UK entry for Eurovision in 1977, staged at Wembley Conference Centre, and finished in second place with Rock Bottom.
Her five top 20 hits also included the theme tune she composed for ITV sitcom No Honestly, which starred Pauline Collins and John Alderton.
Vegetarian De Paul had been seen in recent years in celebrity editions of TV shows such as Come Dine With Me and Cash In The Attic, and she also acted in the Stephen Fry drama Kingdom.
Her friend, broadcaster and campaigner Esther Rantzen, paid tribute, saying: “She was a renaissance woman. She could do everything – she could sing, she could compose, she was an immensely talented artist. She became a huge star but she was also a loyal and generous friend. It’s an absolutely tragic loss.”
De Paul wrote the theme to Rantzen’s series Hearts Of Gold, among the many shows to which she contributed.
She famously appeared at the Conservative Party conference in 1983, performing a song she had written about the party.
She was romantically linked with figures such as Hollywood stars James Coburn and Dudley Moore.
Her agent Michael Joyce said: “Although she was small in stature, she was very big in positive personality. She was always so positive about everything.”
He added that her family had requested privacy.
