UK's FTSE 100 seems to be resistant to any gloomy market data as it surged even after country's GDP fell in the third quarter unexpectedly.

Despite dismal GDP figures, the FTSE 100 gained 35 point on Friday to close at 5242.5 points.

UK's GDP dropped unexpectedly by 0.4 per cent during the three months ended September.

Market analyst Anthony Grech said, "Of course with so many of the larger quoted companies deriving much of their income from outside the UK, the health of our economy is only one part of the jigsaw."

Prudential rose 5.15 per cent to 629.9p. Among miners, Anglo American gained 95p to £24.29, while Xstrata jumped 36p to 997p.

Lloyds Banking Group gained 1.43p to 96.23p, while Royal Bank of Scotland closed at 47.08p, up 1.57p.

Among the mid-caps, Filtrona was the biggest gainer. Shares in Filtrona closed at 172.8p, up 13p.
