IMF fund boosted to stop speculation on troubled economies

The International Monetary Fund has received pledges of an extra $320bn (£199bn) in a bid to stave off speculative market attacks on Spain and other troubled eurozone countries.

Some of the organisation's 188 members have been keen to boost the funds reserves, but the US, the IMF's most powerful member, has refused.

The funding issue is likely to be key at this weekend's meetings of G20 finance ministers and the IMF in Washington.
