March 11 (Reuters) - The UK's main indexes fell on Wednesday, as oil prices remained choppy on lingering concerns from the Middle East conflict, and some disappointing corporate earnings weighed.
The blue-chip FTSE 100 (.FTSE), was down 0.6% by 1103 GMT, while the mid-cap FTSE 250 (.FTMC), fell 0.7%.
Brent crude rose to trade above $90 per barrel as markets doubted whether the International Energy Agency's reported plan for a record release of reserves, which caused oil prices to fall earlier in the session, could offset the supply disruption caused by the conflict.
The energy index (.FTNMX601010), gained 0.5%, with oil majors Shell (SHEL.L), and BP (BP.L), up around 0.5% each as crude prices rebounded.
Most other FTSE 350 sub-sectors traded lower.
Investors also assessed a slew of mixed corporate updates.
Legal & General (LGEN.L), fell 5.5% after the insurer missed estimates for its full-year profit and reported a lower solvency ratio as CEO Antonio Simoes pursues an overhaul.
Robert Walters (RWA.L), dipped 2.9% after the recruiter scrapped its final dividend for 2025 following a swing to an annual pretax loss due to a weak job market.
Balfour Beatty (BALF.L), rose 7.3% after the construction group forecast a high-single-digit percentage rise in 2026 profit from operations, with a record order book heavy with UK power projects, including nuclear power.
Harbour Energy (HBR.L), fell 8.7% after the oil and gas producer's third-largest shareholder, EIG Asset Management, sold about 60 million shares at a discount to the stock's Tuesday close.
