Private schools in England, such as Eton and Winchester College, have significantly more outdoor space compared to state schools.

The Guardian's analysis reveals that Eton students have 140 times more green space than the average state school pupil, including amenities like tennis courts and swimming pools.

Experts highlight that this disparity in green space availability can adversely affect children's mental and physical well-being, as such environments improve cognitive function and reduce health inequalities.

There are calls for private schools to do more to provide green spaces for less privileged children.

Urgent action is needed to enhance state school pupils' access to outdoor areas.
