19 Days to May 7 — Labour and Conservatives Face a Joint Wipeout, Projections Put Combined Losses at 2,910 Seats, and Reform Is On Track for the Biggest Local-Election Realignment in Post-War British History as 47 Councils Change Control

The arithmetic

The 2026 English local elections are the same tranche last fought in 2022, when Labour polled 35% and the Conservatives 34%. Labour is now polling around 20% and the Conservatives around 19%. Both parties’ 2022 successes were built on the collapse of the other; this year’s projected result is the collapse of both. Reform is on 27–32% in the national polls and has been there consistently since May 2025.

Projected Reform gains: 2,800+ seats. Projected Green gains: 400–500 seats. Projected Lib Dem gains: around 200 seats. The combined non-traditional opposition is picking up roughly 3,500 seats from the two major parties — a realignment that redraws the political colour of rural England, the Northern Labour heartlands, and the commuter belt in a single night.

Where Labour is bleeding

Labour’s exposure is concentrated in northern metropolitan boroughs where Reform is now actively campaigning. Wigan, Sunderland, Barnsley, and Rotherham all appear in the projected-loss-of-control list. The Labour decline in these seats is not a generic swing: it is Reform directly inheriting the vote Labour won back from Boris Johnson in 2024. YouGov’s MRP-style regional breakdown has Reform ahead of Labour by 20 points in the North East.

The London borough elections next May are a separate problem entirely; the May 7 races are county and district councils plus a handful of unitary authorities and mayoralties. The Labour strategy for tomorrow’s Cabinet meeting is to lower expectations aggressively. The memo that leaked to The Times on Thursday told ministers to brief journalists that “losing 1,500 seats is the successful outcome.” That is a number the party would have considered catastrophic eighteen months ago.

Where the Conservatives are bleeding

Kemi Badenoch’s party is losing the shires to Reform at roughly a one-for-one conversion rate. The symbolic prizes for Reform are Essex County Council (59 years of continuous Conservative control), Norfolk (74 years), and Suffolk (the same). A single night of counting will end a Tory hegemony older than most voters. Kent and Lincolnshire could go Reform-led coalitions. Hertfordshire may be saved by the Lib Dems rather than by Conservative resilience.

Badenoch herself is on a general-election footing. The Conservative Whips privately believe the party will be wiped out of county government on May 7 and that Badenoch’s leadership survives the night only because there is no one on the 1922 Committee with the appetite to launch a challenge three weeks before the Mandelson texts drop. That calculation may not hold past mid-May.

What Reform actually does with power

The Reform preparation for May 8 is the most underreported story of the pre-campaign. Nigel Farage’s team has spent six months recruiting former council chief executives as advisers and has drafted first-100-day pledges for each likely takeover authority. The manifesto pledge in Essex is to immediately end DEI officer posts, cancel asylum hotel contracts within council planning jurisdiction, and cut council tax by 3%. Two of those three are legally possible; one is a fight with central government.

The bigger prize for Farage is national. A Reform clean sweep of county England on May 7 turns his party from an insurgency to a government-in-waiting in a single news cycle. The parliamentary arithmetic in 2029 only becomes plausible if Reform has competent councillors running real services between now and then. May 7 is the first night of that test. Starmer and Badenoch are, in different ways, auditioning for jobs in 2029 that they may not have the chance to apply for.
