BBC executive Producer Jon Plowman claimed the star's specific cause of her death was a heart attack.
He told Radio 4 this morning, saying: 'It's no age to have a heart attack, as I understand it.'
Plowman, who produced the Vicar of Dibley, added: 'Emma was a gifted comic actress who made any part she played look easy. She was adored by the cast and crew.'
Twitter flooded with tributes to the late-actress, including from Hugh Grant and Dawn French.
Our thoughts are with Emma's family and friends.
