Ofsted chief executive Sir Michael Wilshaw will criticise state schools for failing to provide competitive sport and call for an end to the "all-must-have-prizes" culture in comprehensive schools, which some say discourages competition.
In a speech on Friday, Sir Michael will urge state schools to push competitive sports to create more medalist like Jessica Ennis-Hill.
More than 40% of Team GB in London 2012 attended private school, compared to just 7% of the general population.
The Ofsted chief will also highlight the connection between participation in competitive sports and academic success.
