The head of the World Bank has warned that the global economic crisis could lead to serious social upheaval.

“If we do no take measures, there is a risk of a serious human and social crisis with very serious political implications,” Robert Zoellick said. He pointed to Eastern Europe, which faces the “tricky situation” of fast-shrinking economies and protests. Mr Zoellick suggested governments should start preparing for high levels of unemployment. “In my opinion, in this context, nobody really knows what is going to happen and the best one can do is be ready for any eventuality,” Mr Zoellick said in an interview with Spain’s El Pais newspaper.
