LONDON — European markets were muted on Friday as investors digested a fresh round of corporate earnings and looked ahead to a crucial Spanish election over the weekend.

The pan-European Stoxx 600 was up 0.2% by mid-afternoon. Mining stocks shed 1.3% while oil and gas stocks added 0.9%.

The European blue chip index closed out the previous session 0.4% higher, though the tech sector dropped 2.5% on the back of weak U.S. tech earnings.

Shares in Asia-Pacific fell on Friday as investors reacted to Japanese inflation figures, with the core consumer price index rising slightly in June from the previous month.

U.S. stock future nudged fractionally higher in early premarket trade after the Dow Jones Industrial Average wrapped up a ninth consecutive day of gains, its longest rally since 2017. The S&P 500 and Nasdaq, however, both closed the day in negative territory.

Back in Europe, U.K. Prime Minister Rishi Sunak's Conservative Party suffered a heavy blow in a series of by-elections Thursday night, losing two seats in parliament to the main opposition Labour Party and centrist Liberal Democrats. The results were ominous for Sunak's ruling party as it looks ahead to a general election in 2024.

Spanish voters head to the polls on Sunday in a pivotal snap general election that could end the four-year tenure of left-wing Prime Minister Pedro Sanchez and mark a shift to the right in Europe's sixth-largest economy.

Corporate earnings on Friday came from Swiss miner Glencore. Earnings season kicks off in earnest next week, when Europe's major banks, pharmaceutical firms, automakers, energy giants and aircraft manufacturers are all due to report.

Stocks on the move: Wartsila up 8%, SSAB down 14%

Flat open for European shares

The pan-European Stoxx 600 was little changed at the open. Tech stocks shed 1.6% to continue the previous session's slide, while insurance stocks added 0.8%.

Here are the opening calls

Britain's FTSE 100 is seen around 7 points higher at 7,653, Germany's DAX is set to decline by around 66 points to 16,138 and France's CAC 40 is set to add around 7 points to open at 7,392, according to IG data.

UK retail sales exceed expectations to rise 0.7% in June

U.K. retail sales rose by 0.7% month on month in June after a boost from unusually warm weather, the Office for National Statistics revealed on Friday.

Economists polled by Reuters had projected a monthly rise of just 0.2%.

"Whatever is encouraging this spending, the numbers suggest consumers remain willing to spend money when the opportunity presents itself. For the U.K. economy this is welcome, as robust domestic consumption will go a long way in helping to avoid the economy slipping into recession," said Stuart Cole, chief macro economist at Equiti Capital.

"But today's numbers will likely have been read with some concern inside the Bank of England, as they suggest more work needs to be done in its efforts to dull demand in order to tame inflation, despite the softer CPI figures seen this week."
