Undoubtedly, they are political tests and were chosen with great care for maximum apparent objectivity whilst remaining totally subjective. Sadly, Tony Blair has been on the losing horse with the euro ever since he was forced by John Major's government to make a referendum on the euro a manifesto pledge. This government may have neatly side-stepped or totally avoided a number of manifesto pledges, but there was no way the press were going to let him quietly avoid a euro referendum. Consequently, I can see very little chance of Britain adopting the euro in the next 5-10 years.
