US slips two places in WEF survey

The United States has been overtaken by Sweden and Singapore in the World Economic Forum's (WEF) competitiveness survey for 2010-11.

The change meant that the US slipped two places to fourth in the WEF's latest ranking.

Switzerland, which overtook the US last year, remains the top ranked economy.

Germany rose to fifth, and was the best placed eurozone country. The UK, after falling back in recent years, moved up one place to 12th position.
