uk/local/hounslow/chiswick/">Chiswick, (West London Times) October 22, 2026 – Brentford councillor Guy Lambert has been stripped of his leadership and suspended from the Green Party group on Hounslow Council, following announcements made during a local authority meeting.

Why Was Cllr Guy Lambert Suspended from the Hounslow Green Group?

As reported by Bridget Osborne of The Chiswick Calendar, Cllr Guy Lambert has been removed from his position as Leader of the Green Party group on Hounslow Council and suspended from the local council group. The development was initially revealed to the chamber by Council Leader Cllr Shantanu Rajawat during an unscheduled Borough Council meeting, who stated, as reported by Bridget Osborne of The Chiswick Calendar,

“I am aware, I think, that Cllr Lambert is no longer part of the Green group.”

Addressing his new status in the chamber, Cllr Lambert remarked, as documented by Bridget Osborne of The Chiswick Calendar: “I am a simple councillor, now without even a party.” However, speaking directly to The Chiswick Calendar, Cllr Lambert clarified that he has not resigned from the national Green Party of England and Wales (GPEW) and remains an official member, despite not receiving formal notification from central party administration.

What Did Local Party Co-ordinator Rick Rowe Say About the Suspension?

Detailing the background of the decision on social media, local party co-ordinator and Chiswick Riverside councillor Rick Rowe stated, as quoted by Bridget Osborne of The Chiswick Calendar:

“Following a number of conversations with the Association of Green Councillors (AGC) and Green Party of England and Wales (GPEW), Cllr Guy Lambert has been suspended from the Green Group on Hounslow Council and is no longer Group Leader.”

Cllr Rowe added, as noted by Bridget Osborne of The Chiswick Calendar:

“He remains a member of GPEW. I know this will be sad news for many members. An internal process must now follow, so it would be inappropriate for me to comment further.”

Could Policy Differences Over Zionism and Israel Have Caused the Ousting?

Observations from The Chiswick Calendar suggest that Cllr Lambert’s outspoken political stances may have contributed to his removal. Specifically, he did not support a motion at the recent Green Party conference declaring Zionism as racism, nor does he support the current Israeli regime and its military activities.

This suspension marks the second time Cllr Lambert has faced disciplinary or group departure within a short timeframe. Previously, he served for many years as a Labour cabinet member before resigning from the Labour group in January 2025 following an eight-week suspension in November 2024 over criticisms regarding council support for Brentford businesses. He subsequently joined the Greens in May 2026, becoming the leader of their three-member group as the only councillor with prior experience.

How Will This Affect Hounslow Council Planning Committees?

The unexpected suspension coincided with an unscheduled Borough Council meeting called to pass mandatory national changes regarding the operation of planning committees. The size of the Planning Committee was reduced from 15 to 13 members, with Labour and the Conservatives each losing one seat.

Because Cllr Lambert was slated to continue on the committee but now functions as an independent councillor, council officers will need to review committee compositions to ensure proportional representation across political groups. This follows recent adjustments made after independent councillor Gurbachan Athwal—who faces fraud charges which he denies—had the Labour whip removed.

During the meeting, Council Leader Cllr Shantanu Rajawat proposed appointing 12 nominated members while leaving the 13th seat vacant pending further review. While Liberal Democrat councillor Roger Crouch, Independent councillor Theo Dennison, and Cllr Lambert opposed the measures—with Cllr Lambert describing them as an attempt to prop up the administration—the changes were approved with support from Reform UK councillors.

Background of the Development

The suspension of Cllr Guy Lambert unfolds against a backdrop of shifting political alliances and local administrative adjustments within Hounslow Council. Having transitioned from a long-standing tenure within the Labour Party to serving as an Independent before joining the Green Party in May 2026, Cllr Lambert has built a reputation for outspoken commentary on local governance and international affairs. His departure from the Labour group in early 2025 stemmed from disagreements over economic support for local businesses in Brentford. His recent tenure with the Green Party group concluded abruptly following discussions involving the Association of Green Councillors and national party leadership, intersecting with statutory revisions to council committee structures mandated by national legislative changes.

This political development alters the balance of power within Hounslow Council by reducing the Green Party’s organized group representation and converting an experienced local figure into an independent voice. For local residents in Brentford and across the wider London Borough of Hounslow, the shift means their representative operates without formal party backing, potentially altering how community advocacy, planning committee oversight, and local scrutiny are delivered. Furthermore, council administrators will face immediate procedural adjustments to maintain proportional representation on key regulatory committees, which could influence upcoming policy debates and voting dynamics within the local authority.
