Childcare-ratio plan: What do Clegg doubts mean?

Nick Clegg has told Conservatives he will block government reforms to adult-child ratio limits for childcarers, BBC Newsnight has learned.

In meetings over recent days he said he could no longer back the plan to increase the number of children nursery staff and child-minders can look after.

The deputy prime minister's veto could have funding consequences for the government's entire childcare package.

Allegra Stratton explains the significance of the move.
