Government departments cut £6.7bn more in spending than planned in the year to March, according to official data from the Treasury.

Ministers are to back in principle a cap on the amount people in England pay towards the cost of social care, but without any agreement on funding.

Legislation to change the funding of social care for elderly and disabled people in England could be introduced during this Parliament, Health Secretary Andrew Lansley has said.

Critics say the government needs to provide further details on how it will fund a cap on social care costs and when it will be introduced.
