The FTSE 100 has fallen by almost 1.5 per cent on the back of below-par job figures in the US and mixed trade figures from China.
At 16.21, the blue-chip index was down 1.46 per cent to stand at 5640.24.
The U.S. Labor Department said on April 6 that employers added 120,000 jobs in March. That was the fewest in five months and less than the median economist forecast of 205,000 in a Bloomberg survey.
Markets across Europe have also fallen in early trades with the French Cac 40 and the German Dax down 2.3 and 1.7 per cent respectively.
