A standout performance from the FTSE 100’s mining companies helped the index rise to its highest point since May last year.
The miners gained on Wednesday thanks to renewed optimism from China, which heavily drives demand for their materials.
“The rebound in Chinese markets is catching the attention this side of the globe, as mining stocks in London lead the way higher,” said Chris Beauchamp, chief market analyst at online trading platform IG.
“After huge outflows from Chinese markets over the last year, it looks like investor confidence in the outlook is returning, along with hopes of renewed raw material demand.”
Shares in Glencore, Antofagasta and Anglo American all rose by between 4.6%-5.3%.
The FTSE 100 rose 24.36 points, or 0.31%, to end the day at 7,772.17.
In New York shortly after European markets had closed the S&P 500 was trading down 0.07%, while the Dow Jones was 0.38% higher.
“Sector rotation continues in the US, as the Dow Jones manages to make gains even as the Nasdaq 100 comes under some pressure,” Mr Beauchamp said.
“The rally in stocks has moved into a choppier phase, a change from the relentless gains of the fourth quarter of 2023, and the sideways price action could intensify as we begin the run towards next week’s Fed decision.”
At the end of the day in Europe, Frankfurt’s Dax index was 0.02% down, while the Cac 40 in Paris had closed up 0.62%.
On currency markets the pound had gained 0.02% against the dollar at 1.2796 and had dropped 0.17% against the euro at 1.1688.
In company news, shares in Metro Bank closed down 4.94% after the high street lender announced the abandonment of its seven-day opening hours and a new round of layoffs.
The bank is cutting around 1,000 jobs and said that further staff cuts are possible. It will reduce its workforce of 4,266 by 22% by mid-April. The business had previously been expected to implement a 20% headcount cut.
Shares in Direct Line also dropped, by 4.34%, as the insurer said that it had again rejected a takeover by Ageas, a Belgian peer.
The 237p-per-share offer valued Direct Line at £3.11 billion. Shares in the business ended the day at 216p per share. Last month Ageas offered 231p per share for Direct Line.
