Des O’Connor, 88, was admitted to hospital a week ago following a fall at his Buckinghamshire home. He was said to be recovering and in “great spirits” before his condition suddenly deteriorated.
In a statement, the agent added: “Des, who was 88, was so well-loved by absolutely everyone.
“He was a joy to work with – he was talented, fun, positive, enthusiastic, kind and a total professional.
“He loved life and considered enthusiasm almost as important as oxygen. He adored his family – they were everything to him. He is survived by his wife Jodie, their son Adam and his four daughters, Karin, TJ, Samantha and Kristina.
“Jodie’s world is shattered, she and Adam and Des’s daughters are hurting more than you could possibly imagine,” they added.
