Nick Clegg 'to block childcare ratio reforms' 8 May 2013 Last updated at 22:30 Newsnight's Allegra Stratton says childcare reform has become a key issue for the coalition 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. The ratio changes are set to be implemented in England in September. Whitehall is now waiting for Prime Minister David Cameron to begin "horse-trading," in the words of one source, with the Liberal Democrats over the policy, or let it sink. Insiders indicated they were hopeful they could persuade the deputy prime minister to change his position. But Mr Clegg's spokesman said he "remains to be persuaded" that changing the ratios, as originally envisaged by Tory education minister Liz Truss, was a good idea. Under one and one-year-olds 1:3 Two-year-olds 1:4 Three-year-olds and above 1:8 or 1:13 (teacher-led) Under one and one-year-olds 1:4 Two-year-olds 1:6 The reform, a high-profile element of the government's drive to reduce childcare costs, has run into fierce opposition. In one survey, conducted by the National Children's Bureau, out of 341 early years staff interviewed, 95% said they were concerned about the policy. The government's own adviser on childcare, Professor Cathy Nutbrown, has said the ratio plans "make no sense at all." In February, a coalition formed against the changes called Rewind on Ratios, run by the pre-school learning alliance and supported by - among others - Mumsnet and Netmums. Statutory ratios for carers per child vary depending on age and setting. Those for children aged one-and-under are set to rise from three children per adult to four children per adult. Those for two-year-olds are set to rise from four to six children per adult. Ratios for three-year-olds and over would remain at eight or 13 children per adult, depending on whether a qualified graduate was present. Ms Truss has championed the reforms, saying they will bring Britain into line with other European countries including France and Sweden. She says that allowing minders to care for more children - providing those minders have higher qualifications, a parallel reform she has proposed - would lower the cost of childcare and improve quality, by enabling the profession to attract those with higher salary demands. Sources told BBC Newsnight that if the deputy prime minister does block the plan there will be funding consequences for the entire childcare package, which also includes £1,200 tax breaks on childcare for working parents - a central offer of the coalition government as they try to bring down the cost of living. Britain has some of the highest childcare costs in the world, with many mothers with two or more children saying it does not make financial sense to work. Mr Clegg's spokesman told Newsnight: "The delivery of good quality, affordable childcare is one of Nick Clegg's biggest priorities in government. He has looked very closely at proposals to increase the number of children each adult can look after - and at the very serious concerns raised by parents and childcare providers in the recent government consultation. Nick remains to be persuaded that this is the right thing to do for very young children. Or, crucially, to be persuaded that this would actually help families with high childcare costs. This continues to be discussed in government.
