This is what Tory MPs have been told to say by CCHQ ahead of Osborne’s big speech outlining his renegotiation demands in Berlin:

We have been returned to office with a very clear mandate to improve Britain’s relationship with the rest of Europe and to reform the European Union. Quite frankly, the British people do not want to be part of an ever closer union.

What we seek are principles embedded in EU law and binding on EU institutions that safeguard the operation of the Union for all 28 member states. The principles must support the integrity of the European Single Market. That includes the recognition that the EU has more than one currency and we should not discriminate against any business on the basis of the currency of the country in which they reside. The principles must ensure that as the Eurozone chooses to integrate it does so in a way that does not damage the interests of non-euro members.

We must never let taxpayers in countries that are not in the euro bear the cost for supporting countries in the Eurozone.‎

So Osborne’s ‘demands’ are a statement of the obvious that the EU has more than one currency, a vague commitment that Britain will not be “discriminated against” and a vague commitment that we will not “bear the cost” for bailing out the Eurozone. There is no further detail for MPs. Is that it?
