DAILY MAIL COMMENT: Cameron must call Mrs Merkel's bluff By Daily Mail Comment Piling on the pressure in the row over EU migration, Angela Merkel warns she will withdraw support for the UK's continued membership of the club if David Cameron insists on demanding measures that would undermine the free movement of labour. It's time the Prime Minister spelt out a few home truths to Germany's Chancellor. First, it is not for her to decide whether we stay in the EU. That is a matter solely for the British people and Parliament. German Chancellor Angela Merkel, left, warns she will withdraw support for the UK's continued membership of the EU if David Cameron, right, insists on measures that would undermine the free movement of labour Next, Mr Cameron might like to remind her that, as net exporters to the UK market, our partners need us rather more than we need them. But most of all, he needs to impress upon her that the British people will no longer countenance unrestricted immigration on anything like the scale of the past few years. Indeed, the sheer numbers flocking in from the poorer countries of eastern Europe have put intolerable pressure on our housing, schools, hospitals, transport and welfare system, while driving down wages and threatening social cohesion. As George Osborne said last night, the EU is "not working for Britain." More from Daily Mail Comment... So how depressing that, yesterday, some ministers tried to turn this into a narrow debate about migrants" entitlements to tax credits and other benefits. Yes, a crackdown on welfare tourism must be a vital part of any new settlement - and there is encouraging talk of limiting migrants" free access to the NHS. But since most come to work, not to scrounge, Mr Cameron needs to go further. Shouldn't he insist that nothing will satisfy the electorate short of a radical change, allowing us to admit no more than we can comfortably absorb? Indeed, the sooner the Prime Minister spells out his demands - on this and other crucial matters, such as agriculture and fisheries, foreign and defence policy - the sooner the phoney war can end, and negotiations can begin in earnest. What is clear is that he will gain no real concessions while he lets our partners believe he will back our continued membership, whatever they offer. Surely, he should call Mrs Merkel's bluff, bring forward the date of his promised referendum - and vow to lead the No campaign if his demands aren't met. The anti-family party When Labour left office in 2010, it bequeathed a benefits system which paid parents more to live apart than together and a tax regime that discriminated against stay-at-home mothers. In 2003, it even removed the word "marriage" from all official documents, while presiding over rates of teenage pregnancy and family breakdown that led Unicef in 2007 to label Britain the worst in the developed world for child wellbeing. Meanwhile, to this day, Ed Miliband opposes Tory attempts to redress the tax injustice to single-earner couples and to put marriage at the heart of policy. Yet with breathtaking hypocrisy - and an election just six months away - Shadow Education Secretary Tristram Hunt now seeks to rebrand Labour as the party of the family. Does he take voters for gullible fools? No integrity: Spuriously citing data protection laws, a committee chaired by Speaker John Bercow has permitted the shredding of tens of thousands of documents relating to the MPs" expenses scandal of 2009 Reputation in shreds Spuriously citing data protection laws, a committee chaired by Speaker John Bercow permits the shredding of tens of thousands of documents relating to the MPs" expenses scandal of 2009. With the evidence against them destroyed, no doubt many politicians will be hugely relieved - including some hoping to return to Westminster next year, after being banished in disgrace, and others who never left. But along with those documents, the authorities shredded any hope of restoring Westminster's reputation for integrity.
