Now why would Nick Clegg say that?

PA are reporting:

'Greek exit from the euro could set off a "chain reaction of uncertainty" which would result in a "grinding slowdown in economic activity" across Europe, including the UK, Deputy Prime Minister Nick Clegg has warned.

Mr Clegg dismissed arguments that Greece's economic woes and the instability in the single currency could best be served by a swift return to the drachma, insisting that "no-one rational" could want such an outcome.'

When I read this why do the words 'EU  pension' come to mind? And why do I remember the fact that EU pensions are paid on the understanding that the EU can remove this pension, if in the view of the Commission or the Luxembourg Court, they "fail to uphold the interests of the European Communities".
