Britain "needs to do even more" to help refugees from Syria, Chancellor George Osborne has said, as he called for a "fundamental rethink" of how the UK uses its international aid budget.
Mr Osborne told the BBC money from the £12bn budget could be diverted to councils helping to house refugees.
The PM has said the UK will take in "thousands" more refugees from Syria.
Mr Osborne also said ministers should make the argument for military action against Islamic State militants there.
