Julia Bradbury, Phil Tufnell and Dr Phil Hammond set out to tackle one of the nation's most pressing health issues. Britain's 'secret killers' - type two diabetes, liver and heart disease - affect more than eight million people in the UK. At the nation's largest-ever combined health screening at the Rugby Football League's Magic Weekend in Manchester, 50 NHS nurses, three leading charities and a team of doctors screen hundreds of people to find out if they are at risk of developing one of these three preventable conditions, with shocking results. Dr Phil Hammond also screens a group of famous faces to find out who might develop one of these potentially lethal conditions. And when former EastEnder Ricky Grover, actress and singer Jodie Prenger and actress and comedienne Crissy Rock make some alarming discoveries, they agree to work with Dr Phil to turn their health around. Long Live Britain follows them as they learn how these conditions are affecting their bodies - and what they can do to get their health back on track.
