Uncertainty provokes huge fall for FTSE

The FTSE 100 Index plunged 4% in another panic-driven session today as world markets took a fresh battering from the Greek debt crisis.

In a return to the volatility seen at the time of the banking crisis, London's blue-chip index slumped to within 45 points of the 5000 barrier before closing 138 points lower at 5123, a drop of 2.6%.
