London Markets Retreat as Spirax and Insurers Drag Down FTSE 100

The selling pressure centered on Spirax, which faced a sharp retreat following a lackluster outlook for the valve manufacturer. Compounding the index's woes, the insurance sector suffered a broad selloff. Legal & General led the decline, hit by a wave of brokerage downgrades that soured sentiment across the industry. The combined weakness in these key sectors kept the FTSE 100 under water throughout the morning session, signaling ongoing caution among traders regarding industrial performance and financial sector valuations.
