Anita Rani and Nick Robinson present the centrepiece of the BBC's NHS at 70 season, a live broadcast from Birmingham's Queen Elizabeth Hospital. They celebrate 70 years of the NHS before asking the big questions about the NHS today and in its future, in front of an audience of patients and NHS professionals at the heart of the debate about Britain's best-loved institution. We all remember the Olympic ceremony celebrating and championing the NHS as the best health service in the world. But how good is it at keeping us alive when compared to other countries? While arguments continue in Westminster over a birthday present boost to the NHS budget, how much money does it really need to keep Nye Bevan's promise of free health care for all in the years to come? With an ageing population taking up hospital beds, obesity costing more than all cancers combined and the numbers of children and young people self-harming up threefold in just four years, how does the NHS born in 1948 reinvent itself beyond its 70th birthday? For the first time, the country's leading health and economic think tanks, including the King's Fund, the IFS, the Nuffield Trust and the Health Foundation, have all joined forces to tackle the most important questions facing the NHS at 70. Anita Rani and Nick Robinson are joined by Helen Skelton, who is live at the maternity ward of the Birmingham Women's Hospital next door, while Dr Kevin Fong looks at how new technology could transform the NHS, and Dr Zoe Williams investigates the obesity epidemic.
