In the 2026 United Kingdom local elections held on May 7 across 136 English councils and other regional contests, Reform UK achieved historic gains, securing around 1,453 seats—a net increase of over 1,450—and control of 14 councils, primarily at the expense of Labour's 1,500-seat losses and Conservative declines of 563 seats. This breakthrough in northern England and traditional Labour heartlands builds on pre-election YouGov MRP polling showing Reform leading in multiple Midlands councils and recent by-election wins averaging 34% vote shares. With counting nearly complete as of May 10, minor adjustments from outstanding results could refine totals, signaling voter discontent with Keir Starmer's Labour government on issues like immigration and the economy, while reshaping local governance ahead of potential national shifts.
