Around 1,000 people have turned up at Labour Party street stalls in Whitstable and Canterbury to sign cards wishing the NHS a happy 70th birthday.
Labour describes the health service, established by health secretary Nye Bevan in 1948, as its greatest ever achievement.
Activist Paul Todd, who came up with the idea for the cards, said: “For 70 years the NHS has helped improve the lives of working people.
“It’s always been there in our times of need so it’s right to for us to show our support when it most needs us.”
Members of the public who signed the cards supplied their own messages of support. They included:
The birthday cards have been delivered to the Kent and Canterbury Hospital and the Whitstable and Tankerton Hospital.
