London stocks opened mixed on Thursday as disappointing UK growth data took the shine off recent record highs for the FTSE 100.
The blue-chip index slipped 0.3% to 9,887.60, while the mid-cap FTSE 250 gained 0.4% to 22,211.74.
The latest figures from the Office for National Statistics showed the UK economy grew just 0.1% in the third quarter, slowing from 0.3% in the previous quarter and missing forecasts for 0.2%. September output fell 0.1%, marking the final GDP reading before Chancellor Rachel Reeves delivers her first Budget on 26 November.
The ONS said imports dropped £1.0 billion, or 2%, in September, while exports fell £1.7 billion, or 5.5%, driven by a sharp decline in shipments to the US.
In equities, Endeavour Mining topped the FTSE 100, soaring 13% after swinging to a third-quarter pretax profit of $311 million from a $49 million loss a year earlier. Revenue climbed to $910 million, helped by stronger output from its Hounde mine and firm gold prices.
Other miners also gained, with Fresnillo up 5.1%, while Anglo American and Glencore each rose around 1.1%.
On the downside, 3i Group tumbled 11% after flagging a challenging transaction environment despite reporting higher first-half profit.
Aviva fell 3% as investors took profits following its quarterly update, even as the insurer lifted its cost-synergy targets from the Direct Line acquisition and raised its medium-term guidance.
In the FTSE 250, Wizz Air soared 13% after posting a 24% rise in half-year pretax profit to €450.6 million and unveiling plans to shift capacity to lower-cost markets across Eastern Europe.
Among smaller stocks, WH Ireland rose after confirming it had received a preliminary takeover proposal from Team PLC, offering 0.195 Team shares for each WH Ireland share.
Overnight in the US, Wall Street ended mixed. The Dow Jones Industrial Average climbed 0.7%, the S&P 500 edged up 0.1%, and the Nasdaq slipped 0.3% as President Donald Trump signed a bill to end the record 43-day government shutdown.
