What is the Primary PE and Sports Premium?

The government has provided funding of £150 million per annum since the 2013/14 academic year to provide the Primary PE and Sports Premium. The funding is being jointly provided by the Departments for Education, Health and Culture, Media and Sport, and will see money going directly to primary school Headteachers to spend on improving the quality of sport and PE for all their children.
