The agony aunt, writer and broadcaster Claire Rayner has died at the age of 79, her family said today.

The patients’ rights campaigner, who died yesterday, knew her death was imminent over the weekend and told her relatives she wanted her last words to be: “Tell David Cameron that if he screws up my beloved NHS I’ll come back and bloody haunt him.”

Des Rayner, her husband of 53 years, said: “I have lost my best friend and my soulmate. I am immensely proud of her.”
