The singer and musician Maurice Gibb, one of the Bee Gees pop group, has died at the age of 53.

He had been in a critical condition in a hospital near his home in Florida, where he'd had a heart attack during an operation to remove an intestinal blockage.

Maurice Gibb and his brothers Robin and Barry, who were born in Britain, began singing together as children in Australia in 1958.

The Bee Gees became one of the most successful acts in pop history, reaching the peak of their fame in the 1970s.

Fans and fellow-performers have paid many tributes to Gibb.

A former Bee Gee press agent Chris Hutchins said Gibb was talented, but tortured by the idea that he wasn't as much of a star as his brothers; he said it was this that led to Gibb's years of heavy drinking.
