On Tuesday, British mid-cap stocks experienced a notable downturn, amid heightened speculation over Prime Minister Keir Starmer's leadership. The uncertainty rooted in Middle Eastern conflicts added layers of complexity to existing inflation concerns, further unsettling investors.

Despite growing pressure from over 80 Labour lawmakers to resign, Starmer remains defiant. He dismissed calls for his resignation following setbacks in local elections. The political instability has been tagged by Evercore ISI analysts as exacerbating already tight financial conditions in the UK.

The FTSE 250 index fell by 1.5%, marking its sharpest downturn in six weeks, while the pound also weakened. As oil prices surged, defensive sectors cushioned the blow, reflecting a mixed market sentiment amid escalating global tensions.
