More children may drown without better school swimming provision, the Amateur Swimming Association (ASA) has warned.
Half of seven- to 11-year-olds in England, some 1.1 million children, cannot swim the length of a standard pool, research suggests.
Only 2% of schools surveyed delivered the government's recommended 22 hours a year of swimming lessons.
