The love affair between David Cameron and Nick Clegg is contagious. One month into the Liberal-Conservative coalition, ministers from the two parties are bonding in their respective departments, too. Liberal Democrats have to pinch themselves to make sure their red boxes, pampering by civil servants and ministerial cars are not a dream. Tory ministers, for the most part, are happy to have the Liberal Democrats on board, not least for the cover they provide for the central task of making deep and unpopular spending cuts. The politicians are gradually getting used to coalition politics. Our system is built on looking for areas where you disagree, said a Liberal Democrat minister. When you start looking for where you agree, you realise that you have a lot more in common than you thought. Negotiations on two coalition agreements, which provide the policy prospectus for the new government, proved easier than both parties imagined. But more than 20 tricky issues have been farmed out to commissions, committees and working parties. If the coalition lasts, some of these reviews will boomerang as divisions between the two parties are exposed. There have inevitably been differences behind the scenes in the past month but they seem to have been resolved amicably. Some civil servants mutter that the relationship between Mr Cameron and Mr Clegg is much more harmonious than the one between Tony Blair and Gordon Brown, the unhappy coalition which ran the country for 10 years. The PM and his deputy are trying to bring a more grown-up approach to politics in which the government can be more open about the inevitable disagreements within it. There is brave, over-optimistic talk about weaning our voracious media off the stories about splits and rows it devours. We see this as a real opportunity to change the way politics is done for the better, quipped one Downing Street adviser. Mistakes have been made. The apparently different lines taken by William Hague, Liam Fox and Andrew Mitchell when they visited Afghanistan showed the need for some degree of command and control to prevent the show veering off the road. Yet there is a calm professionalism to the new regime, whatever the tensions beneath the surface. It was displayed during its first crisis - the early, regrettable but inevitable resignation of David Laws, the Treasury Chief Secretary. There are MPs in both parties who believe the happy coalition will collapse under the weight of its own contradictions; some secretly hope so. Yet the partnership may prove more resilient than the doubters think Critics keep their heads down, anxious to avoid blame if it ends in tears. Tory traditionalists, especially the eurosceptics, are uncomfortable with their new bedfellows. They suspect Mr Cameron is snuggling up to the Liberal Democrats so he can nudge his right-wingers out of bed completely. Some Liberal Democrats fret about their party losing its identity and being swallowed up by the Tories. In their hearts, some senior Liberal Democrats cannot get over the fact that Mr Clegg did not hop into bed with Labour, however difficult the parliamentary arithmetic. They fear many people who voted for Liberal Democrat last month will not forgive or forget what he has done. Simon Hughes, the Liberal Democrats new deputy leader, will be keeper of the partys conscience. He didnt rock the boat much yesterday after David Willetts, the Universities minister, raised the inevitable spectre of higher tuition fees. The coalition agreement allows Liberal Democrat MPs to abstain but the party pledged to phase out fees and many election candidates promised to vote against a rise. The main trouble ahead will probably be over the spending cuts. The coalition is preparing the ground for the bad news on a daily basis and trying to pin the blame on Labour. This years 6.2bn of cuts was the easy meat. The nasty medicine will be along soon: tax rises and very tight spending limits in the emergency budget in 11 days, with the gruesome detail of the cuts announced this autumn after a spending review. Despite the loss of Mr Laws, the honeymoon is not quite over yet. It will almost certainly end on 'budget day. Let us enjoy it, Eric Pickles, the Communities Secretary, said this week. It is not always going to be like this. The Independent
