Europe close: Italian and Spanish issues drag

European shares ended Wednesday's session on a mixed note as investors digested an unexpected rise in eurozone inflation and looked ahead to rate decisions from the US and UK amid another dump of corporate earnings.

The pan-regional Stoxx 600 index was up 0.80% at 518.18, alongside a 0.76% gain for the French Cac-40 to 7,531.49.

Spain's Ibex 35 on the other hand slipped 1.23% to 11,065.0, while Italy's FTSE Mib retreated 0.43% to 33,763.86.

Investors were also taking stock of a rate rise from the Bank of Japan - only its second increase since 2007.

The US Federal Reserve was expected to keep rates on hold when it finished a two-day policy meeting, while the Bank of England was to meet a day later for its latest decision.

Eurozone prices increased marginally faster than anticipated in July, a development that might cause the European Central Bank (ECB) to reconsider its plans for further rate reductions.

Inflation within the single currency bloc increased to an annual rate of 2.6% in the year leading up to July, a rise from 2.5% in June, according to a flash estimate from Eurostat, the EU's statistical office.

It was also higher than the 2.4% expected by economists, and above the ECB’s 2% target.

Core inflation remained steady at 2.9% for a third consecutive month. Services inflation eased marginally to 4% and food inflation also eased slightly. Energy prices were up 1.3% year on year, and helped to drive the rise.
