“The UK’s physical activity levels rank 11th out of 15 comparable European nations and the most recent participation data shows significant inequalities remain across different demographic groups and communities.”
In April, Sport England claimed that record numbers of people in the country were now playing sport or taking part in physical activity, but said there is “still much to do”.
