Eurozone crisis uncertainty dominates G20 talks

World leaders meeting at a G20 summit in Mexico have urged European countries to do whatever it takes to overcome the crisis in the eurozone. One official described it as "the single biggest risk for the world economy".

The warnings from the G20 are adding to pressure on politicians in Greece to reach agreement on forming a new coalition government. The New Democracy party narrowly won the election and have until tomorrow to finalise a deal.
