Top shares in London recovered some of the losses they had incurred earlier in the week on Friday, despite a slow start to the day as the market failed to open on time.
The FTSE 100 closed 50.14 points, or 0.71%, higher at 7,117.15.
It followed two days of major losses amid growing fears of a global recession.
The mood had brightened by the end of the week following positive retail sales data from the US.
London’s blue-chip index opened later than usual in the morning, following technical difficulties at the London Stock Exchange which made for a 100-minute delay.
David Cheetham, chief market analyst at XTB, said: “The only real difference with opening later is that those who wanted to execute on the open have been delayed.
“Given that most of Europe is trading higher, the market in London has begun brightly so those wanting to buy may be ruing having to pay a higher price for certain securities than if they were able to trade on the open.”
Meanwhile the FTSE’s European peers charged ahead, with the German Dax and French Cac up 1.31% and 1.22% respectively.
Connor Campbell, financial analyst at Spreadex, said: “The UK index could have perhaps kept pace with its peers if it wasn’t for the pound, which is desperately clinging to its hopes that a rebellious cross-party group of MPs can derail Boris Johnson’s no-deal Brexit plans.”
Sterling was 0.59% higher on the US dollar at 1.215 and up 0.71% versus the euro to 1.095.
