London equities fell on Thursday as investors shrugged off a successful return to the bond markets by Greece four years after the country was rescued with a bailout. In late morning deals, the benchmark FTSE 100 index slid 0.10 percent to 6,629.35 points, as caution also set in before the Bank of England's latest interest rate decision. The BoE announced at midday that it was holding its main interest rate at a record-low of 0.50 percent. The central bank added that its Monetary Policy Committee agreed to keep its quantitative easing stimulus at £375 billion ($628 billion, 455 billion euros).
