European share indexes largely shrugged off Italian Prime Minister Matteo Renzi's resignation after he lost a referendum on constitutional reform on Sunday.

British stocks underperformed most continental markets. The blue-chip FTSE 100 index <.FTSE> gained 0.2 percent compared with a rise of 0.6 percent on Europe's STOXX 600 <.STOXX>.

The FTSE had slipped 0.3 percent in the previous session and 0.5 percent on Thursday. The benchmark index is up more than 8 percent so far this year.

"Despite a 'No' referendum vote in Italy, markets held up rather well. UK banks have seen some buying interest on expectations the sector may have seen the worst, while miners are boosted by higher metals prices and Citi's bullish outlook on the sector," said Jawaid Afsar, senior trader at Securequity.

Citigroup upgraded its stance on Western European miners to "bullish" from "bearish", saying a more robust outlook for the commodity complex in 2017 was likely to lead to cash flow and earnings upgrades.

Citigroup raised its rating on BHP Billiton (>> BHP Billiton plc) to "buy" from "sell", on Glencore (>> Glencore PLC) to "buy" from "neutral" and on Rio Tinto (>> Rio Tinto plc) and Anglo American (>> Anglo American plc) to "neutral" from "sell".

Shares in copper miner Antofagasta (>> Antofagasta plc) gained 4.9 percent, the FTSE 100's best performer. BHP Billiton, Rio Tinto and Glencore rose 1.6 to 4.4 percent. The wider UK mining index <.FTNMX1770> was up 2.4 percent.

British banks also gained, with some investors taking advantage of the sector's decline to a three-week low. The sector index <.FTNMX8350> was up 0.5 percent, boosted by 2.3 percent and 1.8 percent gains in shares of Royal Bank of Scotland (>> Royal Bank of Scotland Group plc) and Barclays (>> Barclays PLC) respectively.

Precious metals miners, however, came under pressure after the price of gold fell by around 1 percent.

Shares in Fresnillo (>> Fresnillo Plc), Randgold Resources (>> Randgold Resources Limited) and Polymetal International (>> Polymetal International PLC) dropped by 2 to 4 percent.

On the macroeconomic front, a survey showed businesses in Britain's services sector grew last month at their fastest pace since January, and the broader economy kept up its momentum in late 2016, even if firms have some worries about the year ahead.
