Britain's economy and politics still reeling a decade after Brexit

June 2026 marks the ten‑year anniversary of the Brexit referendum. Analyses show the United Kingdom’s economy has slowed sharply, with GDP estimated to be 6‑8 % lower than it would have been inside the EU and trade projected 15 % below pre‑Brexit levels. Investment spending has stagnated, with only 0.4 % cumulative growth over three years, and the Bank of England estimates a productivity loss of 2‑5 %. Inflation remains the highest among G7 nations, prompting food prices to rise 20‑30 % and the pound to hit historic lows against the dollar. Unemployment has risen to about 5 % in the third quarter of 2025.

Politically, Brexit has coincided with unprecedented instability. The UK has seen four prime ministers since 2016, and the Conservative Party has been out of power since 2024. Labour, now led by Keir Starmer, suffered a historic defeat to the far‑right Reform UK in the May 2025 local elections, which secured 26 % of the national vote. Analysts say the referendum fragmented the political system, giving rise to new parties and intensifying anti‑immigration rhetoric.

Commentators argue that while not all current challenges stem directly from Brexit, the vote has amplified economic and societal pressures, reshaping the UK's political landscape and leaving the nation grappling with a “swamp of lies and disinformation” and a strained public discourse.
