A recent ICM survey has shown that 85% of 18 to 24 year old's support UKIP's policy of restoring grammar schools to Britain's towns and cities.

The findings prompted fresh questions over David Cameron's decision to abandon the Conservatives' historic support for selective education.

The poll, commissioned by the National Grammar Schools Association, found that support for grammars is strongest among 18 to 24-year-olds, followed by 25 to 34-year-olds.
