Markets tumble Greek riots add to eurozone debt fears

LONDON'S top share index shed a further 1.3 per cent yesterday following riots on the streets of Athens, while worries intensified over eurozone debt contagion, with ratings agency Moody's warning Portugal's debt might be downgraded.

The FTSE 100 ended the day down 69.18 points at 5,341.93, a fourth consecutive session of falls, closing at a level not seen since 25 February.

The Footsie is now 1.3 per cent lower on the year, having been as much as 8 per cent higher on 16 April.

Meanwhile, ratings agency Fitch revised its outlook on Goldman Sachs to "negative" from "stable" due to the risk caused by the civil fraud charges by US regulators. But the agency left the US bank's "A+" credit rating unchanged.
