@Ben - again please try applying critical thought before reposting information like your list above. For example:
1. Why is the time period of 1 year appropriate?
2. What base interest rate did each of the countries start from?
3. What was happening in the Eurozone 12 months ago that might have impacted those countries differently to the UK?
Your assertion is based on insufficient information and logical fallacy. Interest rates the UK suffers on its debt were at near all time lows during the period of the financial crisis, and especially during the recent Eurozone crisis. They are still incredibly low. This was because of many reasons including:
1. UK government debt was/is seen as a safe haven despite the overall indebtedness of our economy, partly because we can't strictly default (Sterling debt) but also because there were so few other safe investments to allocate across (USTs and German bonds being the obvious competitors)
2. We were outside of the Eurozone hence our Sterling denominated debt was more attractive to the market
3. The Debt Management Office is clearly staffed by the worlds best salesmen
4. The markets appreciated the austerity mood music from the chancellor, even though understanding that austerity wasn't really occurring (showed willing at least).
So, the true picture behind those numbers is that UK debt costs are still incredibly low, but they have risen (normalised even) in the last 12 months because many of the other countries were at incredibly high rates 12 months ago. The Eurozone crisis has lessened somewhat since (sticking plasters and incredible economic suffering in Greece and Spain have helped with that) hence lower rates for them.
Overall we can still borrow at very low rates, and I might add that's even after the yS campaign tried to bu**er it up by threatening not to stand by UK debt - which was only headed off by the Treasury guaranteeing all UK debt (before the start of this thread).
