The London market is back at 7,000 after China's manufacturing sector reported its weakest growth in two years on Friday morning.
As world leaders gather in Argentina for the G20 summit, the FTSE 100 slipped 0.8% as shares in miners such as Rio Tinto, Anglo American and Antofagasta slumped.
Connor Campbell of Spreadex says a slowdown in China’s manufacturing sector is not that surprising given the country’s trade war with the US.
"That puts even more pressure on President Xi Jinping to try and move in the right direction with [Donald] Trump in Buenos Aires, something that seems like a huge ask given the latter’s bellicose rhetoric this week."
Eurozone indices have moved in the same direction, with Germany's DAX and the French CAC both down 0.6%.
