Britain's benchmark equity index had its worst one-day fall in more than a month on Wednesday, weighed down by a drop in Standard Chartered and a rise in sterling after brighter Bank of England forecasts on the economy, Reuters reported. The blue-chip FTSE 100 index was down by 1.1 percent, or 71.30 points, at 6,655.49 points in mid-session trading - marking its worst one-day fall since a 1.1 percent decline on Oct. 8. The FTSE 100 index fell to session lows after the Bank of England (BoE) issued its inflation report. In the report, the central bank brought forward its expectation for when British unemployment will hit 7 percent, suggesting interest rates would likely rise earlier than previously flagged from the record low of 0.5 percent.
