This was CNBC's live blog covering European markets.

European stocks closed lower on Wednesday, as regional markets continue to see-saw over the inflation outlook and the trajectory of interest rates.

The pan-European Stoxx 600 ended down 0.37%, with all major bourses in the red. Most sectors also fell, with autos last down 1.3% and with oil and gas stocks declining 1.2%.

Mining stocks dropped 2.1% after Anglo American said it had rejected BHP Group's third takeover bid but extended the timeline for talks.

U.K. inflation came in at 2.3% on an annual basis in April, data released Wednesday showed. This was above the forecast of 2.1%, but much closer to the Bank of England's 2% target than March's reading of 3.2%.

Asia-Pacific markets traded mixed overnight while U.S. stock futures were little changed as investors looked ahead to the widely-anticipated release of Nvidia's latest earnings report out Wednesday.

Traders will also be watching for minutes from the latest Federal Open Market Committee meeting.

Autos fall 2% as concerns about tariffs from China grow

Auto stocks led European markets lower on Wednesday, with the sector last down 1.97% at 10:27 a.m. London time.

Concerns over tariffs grew after China's Global Times newspaper cited an expert from a government-affiliated auto research body who said the world's second-largest economy should temporarily raise import tariffs on gasoline-powered cars with large engines.

Tariffs could go as high as 25%, which would be the highest level possible under World Trade Organisation rules, he said.

Markets see low chance of June rate cut from BOE following UK inflation data

Traders slashed bets that the Bank of England will start to bring interest rates lower this summer, after U.K. inflation figures came in hotter than expected.

While the headline rate fell sharply to 2.3% from 3.2%, this was below a forecast in a Reuters poll of 2.1%. Both core inflation and services inflation, which are being closely-watched by the BOE, were also higher than forecast.

At 8:40 a.m. in London, overnight interest rate swaps showed a 13% probability of a rate cut at the June meeting, down from around 50% before the print. The probability of an August cut had fallen from 70% to 40%, with a reduction in the Bank Rate not fully priced in until November.

The British pound jumped on the news, trading 0.3% higher against the U.S. dollar at $1.274, and 0.27% higher against the euro at 1.174. Both were sterling's highest levels against the currencies since March, according to LSEG data.
