The FTSE 100 backed down from Thursday's record highs as the pound rebounded on reports that the EU was working on proposals for a post-Brexit trade deal with Britain.
London's blue chip index ended the session down 0.28% or 20.8 points at 7,535.44, edging down from record highs of 7,556.24 a day earlier, having been spurred by a decline in the pound amid fears over stalled Brexit talks.
But sterling recovered after a leaked document seen by reporters in Brussels suggested that EU leaders meeting at the European Council summit next week could authorise "internal preparatory discussions" on the shape of a future trade relationship and a transition deal, in a move which could offer Prime Minister Theresa May hope for talks by the end of the year.
It helped prop the pound up 0.3% versus the US dollar to trade at 1.330, and up 0.3% against the euro to 1.123.
David Madden, a market analyst for CMC Markets UK, said: "GBP/USD drove higher today after reports came out that the EU are working on a proposal for a post-Brexit trade deal with the UK, this announcement reversed the dip in the pound yesterday."
He added that weaker-than-expected retail and inflation data out of the US was also weighing down the dollar, lifting sterling further.
"The pound has crawled back most of the losses it incurred in October so the sentiment is turning for sterling."
Across Europe, the French Cac 40 ended the day down 0.17% while the German Dax rose 0.07%.
Brent crude prices were up 1.5% at $57.24 as investors cheered data showing a rise in Chinese oil imports in September, signalling further rebalancing in the commodity market.

GKN tumbled to the bottom of the blue chip index, dropping 34.8p to 318p, as the engineering firm warned that profits will only be "slightly above" 2016 after taking a £40 million hit linked to legal claims and a £15 million writedown.
