we know this, but neither capital nor politics are entirely monolithic. 62% of rUK reject currency union, according to the poll, so this has every possibility of becoming an election issue, starting Friday. The role of the Labour Party is crucial, because it, and it alone, has the capacity to form a government in both countries, no other party stands an earthly chance of doing so.
So politically, either Millibands lot unite with Cameron (or his successor) and reject currency union, or they maneuver towards endorsing it, and risk being seen as compromising the national interest in pursuit of power in a foreign country.
If the rUK electorate believes that rUKLab is prepared to make accommodations with iScotLab which are not in the perceived interests of the rUK electorate, they'll be rejected at the ballot next May.
We won't find out yet whether capital, beit rUK, Euro or world capital (I'd guess Scottish capital is all but irrelevant) favours £ based monetary union, opposes it or is simply seeking an opportunity to Buffet the £.
