The FTSE 100 gained almost 1 per cent as traders put aside concerns over tapering from the US Federal Reserve and concentrated on the improving signals coming from the world’s manufacturing powerhouses.

Michael Hewson, senior analyst at CMC Markets, said: “After the Fed induced declines of recent days it’s nice to see markets concentrating on the more mundane drivers of economic data and reacting to a broad improvement in manufacturing data from both China and Germany.”

The FTSE 100 Index weakened slightly towards the close but was still up 56.03 points on the day, at 6,446.87.
