An SNP MEP has defended the eurozone, saying that the Prime Minister's decision to veto a change to the European Union treaty is bad for Scotland.
Alyn Smith predicted that in six months the UK will be sinking "a lot faster than the eurozone".
At least 23 of the 27 member states are going ahead with their own new treaty to restore single-market credibility and stability following David Cameron's decision.
Mr Smith told BBC Radio Scotland's Good Morning Scotland programme: "He's done this in a vain, selfish, self-indulgent and downright boneheaded way. This was supposed to be 17 plus 10 other countries (that) were going to be led by the UK, and he's made us look really self-indulgent and completely out of the loop.
"This is serious stuff being dealt with, and the UK has made everything that it didn't want to happen absolutely inevitable."
He said it is "not the case" that the UK position would be worse if it was in the euro.
He added: "The UK is utterly caught up in this crisis, and the UK is going to be impacted by this even worse than the eurozone countries are. And the idea that this is the eurozone countries going off on their own: every country but the UK and Hungary is going to be signed up to this.
"There is just no question that this is the UK out on a limb, all on its own, over a hypothetical threat to the city of London. And David Cameron was more interested in a hypothetical threat to the bankers than the British national interest."
When asked if the SNP still wants the euro for Scotland, he said: "Give it six months and I think you will find the UK sinking a lot faster than the eurozone is. The eurozone is getting its act together.
"This deal tonight has been good news for the eurozone, good news for the EU and it's appalling news for the UK and us (Scotland) with it."
