Reform UK's dominant performance in recent council by-elections, netting +68 seats across 228 contests since the 2025 locals, has fueled trader optimism for substantial gains in the May 7, 2026 English local elections across 136 councils and all 32 London boroughs, contesting over 5,000 seats. Recent MRP polls, including YouGov's showing Reform at 26% nationally ahead of Labour (18%) and Conservatives (19%), project 1,300–2,200 net gains for the party, potentially challenging for council control in key areas like the West Midlands. Labour braces for unprecedented losses amid government U-turns, while Reform faces scrutiny over candidate vetting; results could signal shifts ahead of future parliamentary contests.
