Chris Sherwood, chief executive of the RSPCA, said: "Paul O'Grady's love for animals and the incredible way he told their stories inspired countless families to re-home rescue pets and give them a second chance of happiness.

"His tireless campaigning saw Paul recognised with an RSPCA Animal Hero Award for his outstanding contribution to animal welfare, while he once adopted a little lamb Winston from us who had been rescued from a wheelie bin.

"The thoughts of all at the RSPCA are with his loved ones and our friends at Battersea at this difficult and sad time."
