Greens Oust Labour in Historic Council Election Triumph: Haringey 2026

Key Points

• Historic Political Shift: The Green Party has formally taken control of Haringey Council, establishing a new minority administration and ending 55 years of uninterrupted Labour governance dating back to 1971.
• New Leadership: Green Party Councillor Mark Blake has been appointed as the new leader of the council following a crucial vote at Tottenham Town Hall.
• Opposition Abstention: Labour and Liberal Democrat councillors abstained from voting on the council leadership and did not put forward any alternative candidates, allowing the Greens to take power.
• Significant Labour Losses: The Labour group was severely diminished in the local elections, losing 23 of its 44 councillors. Among the high-profile casualties was the incumbent council leader, Peray Ahmet, who lost her Noel Park ward seat to the Greens.
• Cross-Party Maneuvering: In a surprise move, Labour and Liberal Democrat councillors teamed up to defeat the Greens’ mayoral candidate, Andrew Reid. Liberal Democrat Councillor Dawn Barnes was elected to the civic post instead by a narrow margin of 28 votes to 27.
• The Power of the Mayoralty: While the mayoralty is traditionally a ceremonial role with no decision-making powers, the current finely poised balance of power means the mayor’s casting vote could prove highly consequential in the event of a council tie.
• Future Instability: The current political makeup of the council stands at 27 Greens, 20 Labour, and eight Liberal Democrats. However, this precarious balance faces an immediate test with two local by-elections already scheduled.

Haringey (North London News) May 23, 2026 – The most crucial information regarding the historic transfer of power and leadership changes is presented first, followed by the specific details of the council meeting votes, the breakdown of political seats, and administrative context, concluding with the historical background and future projections.

Who Is Now in Control of Haringey Council Following the Local Elections?

The political landscape of North London has been fundamentally reshaped after the Green Party formally seized control of Haringey Council, establishing a new minority administration and ousting the Labour Party from power for the first time in more than half a century.

In a dramatic and historic shift at a full council meeting held at Tottenham Town Hall, Green Party Councillor Mark Blake was confirmed as the new leader of the local authority. The appointment marks the official end of Labour’s unbroken 55-year tenure governing the borough, a streak that had been maintained continuously since 1971.

The transition of power was secured in an unusual fashion during the first post-election gathering of the full council on Wednesday.

Neither the heavily depleted Labour group nor the Liberal Democrats put forward an alternative candidate for the leadership. Instead, both opposition parties chose to abstain during the pivotal vote, effectively clearing the path for Cllr Blake to assume the leadership of the 27-strong Green minority administration.

The dramatic leadership change follows a devastating set of local election results for the borough’s traditional political powerhouse.

The Labour group saw its presence in the chamber drastically reduced, losing 23 of the 44 council seats it had previously held.

The most symbolic defeat of the election came in the Noel Park ward, where the incumbent Labour leader of the council, Peray Ahmet, lost her seat directly to a Green Party challenger, leaving the local Labour party leaderless ahead of the crucial statutory meeting.

How Did Mark Blake Secure the Council Leadership?

The ascension of Cllr Blake to the highest political post in Haringey represents a remarkable personal and political trajectory. He is widely recognised as one of the most experienced figures within the newly formed 27-member Green administration.

His deep familiarity with the inner workings of Haringey Council stems from his previous tenure as a Labour councillor, a role he performed for nearly a decade.

However, Cllr Blake parted ways with the Labour Party in 2023, choosing to sit as an independent councillor for a period before officially joining the Green Party last year. This extensive municipal experience proved vital in anchoring the Greens’ bid for governance, as the party sought to demonstrate it possessed the administrative capability to manage a complex London borough.

Despite his seasoned background, observers at the meeting noted that the swift and uncontested nature of his appointment appeared to catch many in the town hall by surprise, set against a backdrop of intense cross-party tension.

Why Did the Mayoral Vote Shock the Green Party?

While the Green Party successfully secured the leadership of the council, the evening did not proceed entirely according to their blueprints.

An unexpected tactical alliance emerged between the Labour and Liberal Democrat opposition groups, specifically designed to thwart the Greens’ choices for civic positions.

The primary target of this cross-party cooperation was the election of the borough’s mayor. The Green Party had put forward Councillor Andrew Reid as their preferred candidate for the prestigious civic post. However, behind-the-scenes negotiations between Labour and the Liberal Democrats resulted in a coordinated voting strategy that blindsided the newly installed Green leadership.

How Did Dawn Barnes Win the Mayoralty?

Working in strict alignment, the two opposition groups put forward Liberal Democrat Councillor Dawn Barnes as an alternative candidate for the mayoral robes.

When the division bells rang, the combined strength of the Labour and Liberal Democrat blocks delivered a narrow victory for Cllr Barnes, securing 28 votes in favour of her appointment against 27 votes for the Green candidate, Andrew Reid.

Cllr Barnes officially replaces the outgoing mayor, Ahmed Mahbu of the Labour Party. Mr Mahbu was unable to seek re-election to the post after losing his White Hart Lane ward seat to a Green Party candidate during the local elections held on May 7. The loss of his seat was indicative of the wider collapse of the Labour vote across traditional strongholds in the borough.

What Is the Constitutional Significance of the Haringey Mayoralty This Year?

Under normal political conditions in Haringey, the position of mayor is regarded as a strictly civic and ceremonial role. The occupant represents the borough at public functions, chairs full council meetings, and holds no direct policy-making or executive powers. However, given the extraordinarily tight mathematics of the newly elected council, the role has suddenly assumed immense constitutional significance.

The current political breakdown of Haringey Council leaves the Green Party with 27 seats, Labour with 20 seats, and the Liberal Democrats with eight seats. Combined, the opposition parties hold 28 seats to the Greens’ 27.

In the event of a tied vote on crucial budget declarations or policy items, local government constitutional rules dictate that the mayor holds the power to cast the deciding vote. With a Liberal Democrat now occupying the mayoral chair thanks to Labour backing, the Green minority administration faces a continuous challenge to pass local legislation.

Background of the Haringey Political Shift

To fully understand the gravity of the Green Party’s takeover, it is necessary to examine the long-term political history of the London Borough of Haringey.

Established in 1965 under the London Government Act 1963, the borough initially experienced a brief period of Conservative control between 1968 and 1971. However, the local elections of 1971 returned a substantial Labour majority, initiating 55 years of uninterrupted municipal dominance.

Over the decades, Haringey became synonymous with urban Labour politics, navigating the turbulent eras of municipal socialism in the 1980s, the New Labour years, and internal party fractures between centrist and left-wing factions in the 2010s.

The borough was long considered a “safe” laboratory for Labour policy, making the sudden loss of 23 councillors an unprecedented institutional shock.

The rise of the Green Party in Haringey has been building steadily over several electoral cycles, driven by shifting demographics, local campaigns regarding low-traffic neighbourhoods (LTNs), housing redevelopments, and environmental concerns in urban areas.

By capitalizing on dissatisfaction with the national political landscape and localized grievances, the Greens managed to systematically dismantle Labour’s historic majorities in wards like Noel Park and White Hart Lane, culminating in the historic minority administration formed at Tottenham Town Hall.

Prediction: How This Development Can Affect Residents and Local Stakeholders

The transition to a Green minority administration is highly likely to alter the operational and political realities for residents, local businesses, and community stakeholders within the London Borough of Haringey over the coming months.

For the local population, the immediate effect will be felt through the inherent fragility of a minority council. With 27 Green councillors facing a combined opposition of 28 Labour and Liberal Democrat members, the passage of any major local legislation, particularly the setting of the annual council tax budget, will require intense negotiation. Residents may witness political gridlock or significant compromise on key municipal policies.

Shift in Local Environmental and Housing Policies

The Green administration is expected to place a heavier emphasis on environmental initiatives, waste reduction, and sustainable urban planning. This could mean the expansion of cycling infrastructure and stricter environmental conditions attached to new property developments. However, because Labour and the Liberal Democrats control the mayoralty and hold a combined voting majority, extreme policy proposals are likely to be moderated or blocked entirely.

Near-Term Electoral Instability

The stability of local services and governance will remain uncertain due to the two upcoming by-elections already scheduled for vacant council seats. Depending on which parties secure those seats, the balance of power could tip further against the Greens, or conversely, give them a more workable mandate. Stakeholders relying on long-term council funding or policy continuity should prepare for a period of political maneuvering as all three parties test the limits of this new constitutional arrangement.
