Cameron and Clegg renew coalition vows David Cameron and Nick Clegg will on Monday alarm some in their own parties with a wholehearted renewal of their coalition vows, in a mid-term relaunch which includes a new drive to grapple with the "holy grail" of cutting the cost of childcare. After months of disagreement on issues including Europe and Lords reform, the prime minister and his deputy will insist that "on the things that matter most" the two parties have a shared agenda. Mr Cameron and Mr Clegg will list the coalition's achivements in a "mid-term review" and set out a new programme whose delivery will stretch well into the next parliament. In a joint foreword they concede they have their political differences, but express their support for the coalition in words that will concern Tory and Lib Dem MPs who feel increasingly constrained by it. "On the things that matter most - the big structural reforms needed to secure our country's long-term future - our resolve and sense of shared purpose have, if anything, grown over time," they say. The document sets out a range of reforms that will be passed into law before the election but will not be implemented until the next parliament, including a simplified single state pension and a £75,000 cap on social care costs for the elderly. It also sets out plans to develop the high-speed rail system to Manchester and Leeds and an ambition to bring more private sector investment into roads. Both policies will take many years to roll out. With the overarching coalition objective of eliminating the budget deficit by 2018 and reforming the education and welfare system, the two parties are increasingly setting out policies whose delivery will span the 2015 election. Aides to Mr Cameron insist he wants an outright Tory majority at the next election and Lib Dem strategists dismiss talk of a long-term strategic relatonship with the Conservatives. However the two parties have managed to put aside disagreements on issues including Europe, Lords reform and the Leveson report to fashion a new policy agenda for the rest of the parliament, including childcare reform. Mr Cameron says cutting costs of childcare is his "holy grail" and he will confirm within weeks that parents will be helped through the tax system with their costs, probably through the award of vouchers. Meanwhile Liz Truss, education minister, has drawn up plans to ensure that the £6bn-£7bn of state support already paid for childcare delivers better results, including cutting costs by allowing carers to look after more children. In England nursery staff are only allowed to look after four children, while in France that ratio is 1:8.
