Westminster Elections 2026: Tories Retake Council on 35% Vote

Conservatives win Westminster City Council on 7 May 2026 with 32 of 54 seats and just 35.1% of the vote as Labour's London coalition fractures.

The Conservatives recaptured Westminster City Council on 7 May 2026 with 35.1% of the vote — the lowest share ever recorded by a winning party in the borough — after Labour's vote collapsed by 16 points and a combined 34.7% cast for the Greens, Reform UK and the Liberal Democrats delivered exactly zero councillors between them. That is the story of Westminster in one sentence: not a Tory revival, but a fragmented anti-Labour majority funnelled by first-past-the-post into a party that gained only 3.5 points on its 2022 wipeout. The council responsible for Downing Street, Buckingham Palace and Oxford Street has become the clearest laboratory in England for how Britain's electoral system will convert Nigel Farage's national polling into seats — and for how Keir Starmer's coalition is coming apart in the middle.

The headline numbers are stark. According to Westminster City Council, the Conservatives took 32 seats to Labour's 22 across the 18 wards contested. The BBC's constituency page confirms a swing of nine seats in each direction, ending Labour's only term of control since the borough's creation in 1965. The compiled ward-level returns show the Conservatives on 47,619 votes (35.1%), Labour on 40,986 (30.2%), the Greens on 24,105 (17.7%), Reform on 14,610 (10.8%) and the Liberal Democrats on 8,389 (6.2%), per Wikipedia's aggregation of the returning officer's declarations.

The Tories won Westminster by standing still

Paul Swaddle, the new Conservative council leader, inherits the smallest mandate any winning party has ever held in Westminster. His party's vote share rose by only 3.5 points from the 38.6% it polled when it lost the council in 2022. What changed was not the right — it was the left.

Labour's vote fell 16.1 points, from 46.3% to 30.2%, according to the aggregated ward returns. The party held 28 seats going into polling day, having already lost two by-elections in West End (September 2024) and Vincent Square (February 2025), per the Wikipedia summary. In several inner-city wards the collapse was sharper still: in Church Street the Labour slate lost roughly 28 points, and in Bayswater — a three-member ward Labour won comfortably in 2022 — the Conservatives took two of three seats with vote shares under 39%.

The pattern echoes Sir John Curtice's national reading. Writing for the BBC, Curtice found Labour's vote down 18 points on average from its 2022 and 2024 benchmarks, with the drop "especially sharp in places where the party was previously strongest and in wards where many people identify as Muslim." Westminster fits: Church Street, Harrow Road and Queen's Park — Labour's traditional northern spine of the borough — saw the largest Green surges in the capital's Conservative-facing borough.

Curtice's verdict on the Conservative recovery is worth quoting plainly. Westminster, he wrote, was the party's "one bright spot" — but "this success was a reflection of a sharp 17-point drop in Labour support rather than an indication of any progress made by the party itself — its own tally too, fell by five points" on a ward-weighted measure.

The vote nobody won: 34.7% went to zero seats

The most consequential number in Westminster's count is not 32 or 22. It is 34.7 — the combined share taken by the Greens, Reform UK and the Liberal Democrats, which produced no councillors at all.

The Green Party in particular built the second-largest bloc of votes in three wards without electing a single member. Church Street returned Green candidates on 24–29% in a ward Labour held with reduced majorities. In Abbey Road, the defected Conservative-turned-Reform councillor Alan Mendoza polled 19.3% and lost his seat; three separate Reform slates and three Green slates in the same ward divided the anti-Labour, anti-Conservative vote so cleanly that the Conservative incumbents were re-elected on shares in the low 40s.

This is not a Westminster peculiarity. The BBC's national analysis of the 2026 English elections concluded that "the first-past-the-post system favoured Reform in this English local elections" — but only where its vote was geographically concentrated. In the capital, where the anti-Labour vote splintered four ways, the same system worked in the Conservatives' favour. In Havering, where it stacked, Reform took 39 of 55 seats and won its first London borough. In Westminster, where it did not, Reform's 10.8% produced nothing.

The council's own Notice of Election, signed by Returning Officer Stuart Love on 30 March 2026, offers the primary-source frame: 54 seats, 18 wards, plurality-block voting. In three-member wards, voters cast up to three ballots. The mechanic rewards discipline and punishes fragmentation. That is precisely what happened to the Green surge.

The London map has six colours now — Westminster is the exception

Zoom out and Westminster looks like the odd one on the board. According to BBC London's post-election survey, Labour lost mayoralties and councils in Hackney and Lewisham to the Greens, lost Waltham Forest to the Greens outright, and dropped Haringey, Brent, Waltham Forest, Southwark, Enfield, Barnet, Lambeth, Wandsworth and Newham into no overall control. Reform UK won its first London council in Havering; Aspire retained Tower Hamlets. For the first time, six parties run councils in the capital.

Westminster is one of the very few boroughs where the fight remained bilateral. Curtice again: it "is now one of the few places that is still primarily a Conservative vs Labour battleground." That is what allowed the Conservatives to win it while losing about half the seats they were defending nationally, per the BBC's England-wide results tracker, which recorded Reform on 1,454 council seats and 14 councils — up from a standing start — while the Conservatives sank to nine councils.

The counter-example is Wandsworth, where the Conservatives became the largest party but fell short of a majority, per BBC London. Where the anti-Labour vote had a clear Tory alternative in inner south-west London, the party gained; where Reform and the Greens split it further out, the Tories were caught in the same pincer as Labour.

What Swaddle inherits — and the Oxford Street trap

Swaddle's first fight was already scheduled before he took the chair. Within 24 hours of the count, Transport for London published traffic orders enabling Sadiq Khan's £150m pedestrianisation of Oxford Street between Orchard Street and Great Portland Street. The BBC reported that Swaddle called it "a stitch-up, plain and simple", accusing TfL of pushing through the notices "the day after an election, when all eyes were on the results."

The scheme was approved in March 2026 after Khan invoked a Mayoral Development Corporation — a statutory device that transferred planning power over the street from the borough to City Hall, permitted by the Labour government via new primary legislation. That timing is important. In the campaign, Swaddle told BBC London that the plan lacked detail on "how it's going to be policed, how emergency services will access, how deliveries will access, and how our less-abled residents will actually get up and down this mile-long street," per BBC London's pre-election feature. Now he governs a borough whose signature street is no longer his to plan.

The BBC's transport correspondent Tom Edwards noted that a judicial review is the only realistic legal route, but that the council would need to justify the cost to local taxpayers, according to the BBC's Oxford Street coverage. That decision — whether Westminster City Council spends public money challenging a Labour mayor whose government engineered the very power grab in Whitehall — is the first test of what a Conservative Westminster means in practice.

Diplomat View

The Westminster result is not a Conservative comeback. It is what happens when a governing party loses 16 points and the opposition is split five ways under a system designed for two. Kemi Badenoch's Conservatives took Westminster with a lower share than they lost it with in 2022 — 35.1% versus 38.6% — and the party's own analysis, as reflected by Curtice, concedes as much. The forecast: if Reform's national polling holds and Farage builds any organisational depth in central London ahead of the next general election, the Tory hold on Westminster's parliamentary seats becomes precarious in a way the council result disguises. The condition for revision is straightforward. If Reform breaks 15% in the borough at the next Cities of London and Westminster contest, or if the Greens elect a single councillor in a by-election in the northern wards, the 2026 result reads as ceiling, not floor. If neither happens, Swaddle's minority-mandate majority looks stable through 2030. Either way, Labour's problem is not the Conservatives — it is that its 2024 coalition is defecting in four directions at once, and first-past-the-post has stopped hiding it.

What to watch

• Summer 2026: TfL begins closing the first traffic-free section of Oxford Street "by the end of this summer," per BBC News. Swaddle must decide whether to bring a judicial review of the Mayoral Development Corporation — the first material test of his mandate.
• Autumn 2026: Labour's National Executive Committee reviews London strategy after losing 459 councillors in the capital, per BBC live coverage. Sir Sadiq Khan has already called the results a "wake-up call" and blamed the government, not the boroughs.
• Late 2026 / early 2027: Any Westminster by-election will be the first live test of whether the 34.7% that went unrepresented on 7 May consolidates behind one challenger — most plausibly the Greens in Church Street or Reform in Abbey Road, where the largest opposition blocs already exist.

The Bottom Line

The Conservatives did not win Westminster back — Labour lost it, and first-past-the-post rounded the result up. A 35.1% winning share and 34.7% cast for parties that took no seats is the actuarial signature of a broken two-party system, and Westminster is now the cleanest place in England to watch it fail. If the fragmentation Curtice describes hardens, the next election here will not be a Conservative-versus-Labour contest at all — and the borough that houses Downing Street will elect its councils by accident of vote splits rather than mandate.
