The NHS turns 65 today and to celebrate we're taking a look at how the health service has evolved over the years.
First established on July 5, 1948, the NHS promised cradle to grave care, free for everyone, rich or poor.
Until then Brits had to rely on insurance policies to pay for their health care as most could not earn enough to pay medical bills.
The Labour Government had promised a raft of welfare measures - including the NHS - when it was elected in 1945.
Health Minister Aneurin Bevan was put in charge of introducing the new service, which was based on need, not ability to pay.
It is now the world’s largest publicly funded health service and has helped save millions of lives.
From the first vaccination programmes in the 1950s to today's ground-breaking developments in robotic heart surgery, these 65 interesting facts illustrate some of the landmark changes, which have helped shape the NHS into what it is today.
