Public Health England has been established to protect and improve the nation’s health and wellbeing and to reduce inequalities.
It will lead on the development of a 21st-century health and wellbeing service, supporting local authorities and the NHS to deliver the greatest possible improvements in public health. It came into being in April 2013.
