  EU 'discussing changes to treaty', UK PM says

  He said that proposals on possible treaty changes could be put forward in December, but that he has "secured a commitment that would protect the interests of the UK".
  The prime minister said that Wednesday's meeting, which he would attend, "will give us time to finalise banking recapitalisation and agree a comprehensive policy to put the euro on a more secure footing".
  Before the morning meeting, Greek Prime Minister George Papandreou urged Europe to "act decisively and effectively" to contain the troubles.
  The BBC's Europe correspondent Chris Morris said the summit was an indication of how much still needs to be decided.
  He said: "Everyone now acknowledges that previous decisions on a second bail-out for Greece are insufficient.
  If you don't want to be scared, turn away now. Italy needs to borrow €250bn next year just to refinance its existing debts.
  "Far more of its debt will have to be written off, and that means banks and other financial institutions will have to take a much bigger hit. But how much debt, and how big a hit?"
