George Osborne on 'tax-free childcare' plans
Chancellor George Osborne says he wants to expand a new childcare tax credit scheme to include parents who stay at home because they are full-time carers.
The government says the overall scheme - set to replace the existing system of employer-supported childcare vouchers - will help 2.5 million families.
But Labour says there has been a cut in support since the coalition took power in 2010.
Mr Osborne was also asked about zero-hours contracts. He said that "we want to make sure that the rights of people who go to work are not abused".
