The Greek government has indicated that it has secured sufficient backing for a debt swap deal that will enable it to avoid defaulting on its debts. A Greek official has said that more than 80 per cent of bondholders had agreed to the plan, above the threshold required for Athens to be able to push through the deal. Greece needs to carry out the debt swap before it gets a second bailout. A formal announcement on the take-up of the swap will be made today.
