[BOE Governor Mervyn King] kept the door open for more stimulus in his speech Tuesday. “With inflation falling back and wage growth subdued, there is scope for interest rates to remain low and, if necessary, for further asset purchases, to prevent inflation falling below the 2% target,” he said. The annual rate of inflation in the U.K. dipped to 4.2% in December from 4.8% a month earlier, and is expected to slow sharply this year.
