The blue chip FTSE 100 <.FTSE> index was up 0.1 percent to 6,868.96 points at the close, in line with the broader risk-on mood across European markets.

The dollar softened after the minutes of the U.S. Federal Reserve's July policy meeting showed that policymakers were divided over whether to raise interest rates soon.

This helped support commodity-related stocks, as dollar-denominated commodities became cheaper for holders of foreign currencies.

Antofagasta (>> Antofagasta plc), Anglo American (>> Anglo American plc), BHP Billiton (>> BHP Billiton plc) and Glencore (>> Glencore PLC) rose between 1.6 percent and 5.2 percent.

"We've had some comments in the minutes from the Federal Reserve last night which ... were slightly more dovish than expected, so it's actually caused a bit of relief there because there were some fears that they were going to hike rates before the market's ready," said Jonathan Roy, advisory investment manager at Charles Hanover Investments.

The FTSE 100 index, however, was trading below a 14-month high hit earlier in the week, having been supported by the Bank of England's decision to cut interest rates to a record low and by post-Brexit weakness in sterling.

"We've seen a rally very much based on quantitative easing from the Bank of England and expectations of maybe further easing going forward. However, as this story starts to die out, people are looking for new reasons and new catalysts to actually push the market to fresh highs from here," Roy added.

Home improvement retailer Kingfisher (>> Kingfisher plc) advanced 1.9 percent after reporting an increase in sales over the three months, and said that it had seen no impact yet from Britain's June 23 vote to leave the European Union.

Companies which went ex-dividend and traded without entitlement to their latest dividend payment fell, however, with the likes of Pearson (>> Pearson plc), British American Tobacco (>> British American Tobacco plc) and Legal & General (>> Legal & General Group Plc) all trading in negative territory.

Among the mid-caps, a well-received set of second-quarter results also boosted the shares of Kaz Minerals (>> KAZ Minerals PLC), which jumped 10 percent and touched a 4-month high.

"KAZ’s cost-cutting efforts are bearing fruit, which, combined with a weaker tenge, resulted in profits being pleasingly somewhat ahead of our expectations," Yuen Low, analyst at Shore Capital Markets, said in a note.

Bookmaker 888 (>> 888 Holdings Public Limited Company) gained in late trade, ending 2.4 percent higher, after Rank Group said that it was withdrawing its joint proposal with 888 of a possible combination with William Hill (>> William Hill plc).

William Hill, which had rejected prior offers of a merger, turned lower, and ended down 1.5 percent.
