BBC News - In graphics: Eurozone in crisis

One of the main causes of the currency crisis in the eurozone is that virtually all countries involved have breached their own self-imposed rules.

Under the convergence criteria adopted as part of economic and monetary union, government debt must not exceed 60% of GDP at the end of the fiscal year. Likewise, the annual government deficit must not exceed 3% of GDP. However, as the maps show, only two of the 16 eurozone countries - Luxembourg and Finland - have managed to stick to both rules.

Overall, Greece is the worst offender, with debt at 115.1% of GDP and a deficit of 13.6% of GDP. But among the bigger economies, Italy's debt is even higher than Greece's as a percentage of GDP, while Spain's deficit is 11.2% of GDP. If the UK were in the eurozone, it would also fall foul of the criteria, with its debt now standing at 68.1% of GDP and its deficit at 11.5% of GDP.
