Britain's economy barely slowed in the third quarter despite the Brexit vote shock, further diminishing the chance of a fresh interest rate cut by the Bank of England next week, Reuters reported. Gross domestic product expanded by 0.5 percent in the July-September period, less rapid than the unusually strong growth of 0.7 percent seen in the second quarter but comfortably above a median forecast of 0.3 percent in a Reuters poll of economists. Compared with the third quarter of last year, growth picked up to 2.3 percent, the strongest pace in more than a year, according to the preliminary figures from the Office for National Statistics.
