A new survey of school sports leaders reveals that they expect to see a fall in competitive sporting events provided in schools.
The sports leaders also expect to see fewer children participating in at least two hours of sport each week.
David Cameron promised a rethink on school sport after plans to cut all funding provoked an angry backlash from children, teachers and sports stars.
Andy Burnham said: “In 1997, Labour inherited a weak school sports system. We changed that to ensure that every child had the opportunity to take part in high quality sport, including competitive sport.
“Michael Gove’s ill-informed decision to scrap the entire grant for school sports prompted an angry backlash – and forced the Prime Minister to promise a rethink. But this survey shows that nothing has changed.
“A world-leading school sport system is being dismantled before our eyes. It is hard to imagine a more depressing sight in the run-up to an Olympic Games on home soil.
“Young people are bearing the brunt of Michael Gove’s poor decision-making. They deserve better than this but it’s what we’ve come to expect from this incompetent Government. By breaking promise after promise, they are losing support and goodwill.”
