(ShareCast News) - London stocks finished on the back foot on Tuesday after a worse-than-forecast slowdown in third quarter UK economic growth.UK gross domestic product rose 0.5% in the third quarter compared to 0.7% in the second quarter, well below estimates for a 0.6% increase, the Office for National Statistics (ONS) revealed. On a year-on-year comparison, GDP unexpectedly eased to 2.3% from 2.4%.The ONS said a 0.7% increase in services activity was offset by 2.2% fall in construction growth and a 0.3% drop in manufacturing production amid a slowdown in China's economy."The lacklustre GDP figures revealed today should come as little surprise. A relatively strong pound, coupled with a wounded Chinese economy, has dampened demand for exports," said Dennis de Jong, managing director at UFX.com.Howard Archer, chief UK and European economist at IHS Global Insight, said the easing in GDP "reinforces our belief" that the Bank of England will hold off on raising rates until the second quarter of 2016.US dataUS durable goods orders fell slightly less than expected last month.

The Markit 'flash' US services purchasing managers index fell to 54.4 in October from 55.1 in September, although it remained comfortably above the 50 threshold indicating growth. Analysts had been expecting a reading of 55.5.The US S&P/Case-Shiller Composite-20 House Price Index rose to 5.09% year-on-year in August from 4.91% a month earlier, missing estimates of 5.10%."Major numbers from the US this afternoon did not live up to expectations, with durable goods and consumer confidence both falling short; most investors would be inclined to agree the environment does not yet seem right for an increase in US interest rates, an idea Janet Yellen seems in no hurry to dispel," said Chris Beauchamp, senior market analyst at IG.The Fed will announce its latest policy decision on Wednesday but many analysts expect the central bank to keep interest rates unchanged.
