LONDON (Reuters) - The top share index fell 1.4 percent on Thursday as sagging commodity prices dented miners and energy stocks, while reduced risk appetite hurt banks.
The FTSE 100 <.FTSE> ended down 74.43 points at 5267.70, its biggest daily fall for three weeks, after closing 0.1 percent lower on Wednesday.
Miners were the biggest drag on the index as metal prices were pressured by a stronger dollar as the demand outlook darkened.

"There's been a correlation of strength in metal prices as the dollar weakens and that is now reversing," said Grahame Exton, fund manager at Tilney Investment Management in Liverpool.

The mining sector <.FTNMX1770> is still up 95 percent this year compared to a 19 percent gain for the FTSE 100.
An already weak market retreated further after Bank of America-Merrill Lynch cut its 2010 growth outlook for the bellwether semiconductor industry, sending U.S. equities <.DJI> deep into negative territory.
In Britain, the Office for National Statistics said the public sector had a net cash requirement of 5.9 billion pounds last month, nearly twice expectations.
The ONS also said retail sales rose 0.4 in October, slightly below forecasts of 0.5 percent.
"There's been a bit of a reality to check, but to be honest I though it would have kicked in sooner ... We've reached dizzying heights. It appears this market sees every dip as a buying opportunity," said Philip Gillett, sales trader at IG Index.
