The Iraq war has certainly had a short term effect on the £.
It is now rising since the war was at the shorter end of expectations, and this may well give some policy flexibility and provide some relief to a Chancellor whose calculations on the economy have been somewhat distorted, or if you prefer, too optimistic.
Tax revenues have been less than expected, growth has been less than predicted, and due to increases in public spending, there has been concern that interest rates might have to rise or taxes increased.
I would have thought the Gordon Brown has taken all this on board and thought about the implications of being part of a larger currency and the way it would reduce his options in the future.
Given that he is chancellor he is perhaps more likely to want to retain some of the economic tools at his disposal rather than recommend they be taken away.
Currently the broadsheet press in the business sections is taking great pains to point out that UK unemployment is one of the lowest in the EU and falling (partly because of increased government spending) and puts this squarely upon the restrictions of government borrowing as a percentage of GDP in the Euro zone.
I personally think its because UK workers are easier and cheaper to dispose of when economic times get tough than their counterparts in the Euro zone.
Its also because we are cheaper as workers, we work more hours and we get less company benefits compared to say German workers who recieve far more generous redundancy and pensions terms.
What having the Euro would do for UK citizens is allow them access to capital from all over Europe without the difficulty in trying to operate accounts in another currency, this would lower our interest rates, and especially would be beneficial for companies in the UK who wish to invest in latest technology.
It would make the price of goods and services directly comparable, think of the ridiculous price of cars in the UK compares to much of continental Europe, now imagine such price differencials on CD’s, clothes insurance air travel and many other items.
Here is a true story, friend of mine went to Bruges not three weeks ago, he was sat with his wife at one of the main square cafe/bars.
Bruges is well equipped for the UK tourist, everyone speaks English and they will take UK money directly, no need to change into Euros.
My friend was drinking those small bottles of beer and was paying in £, keeping his Euro for the many gift shops.
He switched to Euro for the last couple of drinks since he wanted £ money for fuel on the journey home.
The beers cost something like £1.40 and he thought no more of it, but when he paid in Euro it cost E1.7.Which is considerably less.
This is not apparently at all unusual either, many other goods are far better paid directly in Euro and work out much cheaper than in £.
Chancellors can talk all about policy, nationalists can talk all they want about sovereignty, but if keeping the £ means paying up to 33% more than I need to for the goods and services I want, the £ can go tomorrow as far as I’m concerned.
