UK Markets Slump as PM Keir Starmer Faces Potential Resignation

British financial assets experienced a broad sell-off affecting government debt, the national currency, and equities, according to reports of a potential leadership challenge against Prime Minister Keir Starmer. These reports suggest that Starmer could face an imminent resignation, possibly as early as today, triggering significant political uncertainty across financial circles.

This slump arrives at a sensitive juncture for the UK economy, as Construction PMI data released on May 7, 2026, showed a sharp contraction to 39.7, significantly missing the 45.7 forecast. In comparison to European peers, Services PMI in Spain stood at 47.9 while Italy recorded 49.8 per market data, reflecting broader regional economic pressures that are now compounded by the political crisis in London.

Investors are now closely monitoring any official announcements from Downing Street to confirm the fate of the British leadership, amid fears of continued volatility for the pound. Looking ahead at the economic calendar, there are no major UK data releases scheduled for the remainder of the week, leaving political developments as the primary driver for local market sentiment.
