The schools watchdog for England, Ofsted, has said the "pupil premium" for disadvantaged children is not being used effectively by head teachers.

David Laws, minister for schools, said the government want many more schools to use the Pupil Premium properly and that there is an accountability mechanism to ensure the money is used to best practice.

"This is balanced approached and I am convinced it is the right [one]," he told the Today programme.

On the subject of Nick Clegg's apology over breaking the pre-election tuition fee policy, he said that all Liberal Democrats have "colective responsibility".

He told John Humphrys that the party ought to have reflected in their manifesto that the only way the policy could have been implemented "was in a coalition government and the other two parties were committed to increasing fees".
