Greenwich (South London News) May 16, 2026 – A Green Party group that surged to 13 councillors in the South East London borough has said its role in holding the Labour administration to account will be central over the next four years. In a statement reflected in the reporting by MyLondon, the party framed scrutiny of the council’s decisions as a key part of its responsibilities after its strongest ever local election result in the borough.
The election result has changed the balance of opposition in Greenwich, with the Greens overtaking the Conservatives to become the main challenger to Labour in the council chamber. That shift matters because opposition groups do more than debate policy: they question decisions, probe spending and test the administration’s plans in public.
Who is leading the new Green group?
As reported by MyLondon, Tamasin Rhymes has emerged as the leading figure in the group after retaining the Shooters Hill seat she first won in a by-election last June. Rhymes, who was previously the only Green councillor in Greenwich, said the party was “hugely proud” of its campaign and said it had “built massively” from the single-seat position it held less than a year ago.
Her election as leader gives the Greens a clear point of focus inside the council and a public face for their opposition work. The party’s rise also reflects how quickly local political fortunes can change between a by-election and a full borough vote.
What changed in the Greenwich election?
The Greens increased their representation by 11 seats, reaching 13 councillors in total, according to the report. That scale of gain is significant in a borough where Labour remains in control, because it elevates the Greens from a small presence to the formal opposition group.
The Conservatives, who previously held that role, were overtaken by the Greens, marking a notable reshaping of the borough’s political make-up.
For local voters, that means the most visible challenge to Labour is now likely to come from Green councillors rather than Conservative ones.
Why does scrutiny matter now?
Opposition scrutiny matters most when a party has enough councillors to raise sustained questions across committees, meetings and public debate.
With 13 councillors, the Green group is likely to have a more regular platform to challenge Labour proposals, press for detail and draw attention to issues affecting residents.
The party has presented that scrutiny role as a duty rather than a political slogan, describing it as “absolutely crucial”.
In practical terms, that means the group will be expected to respond to planning, housing, environment, transport and service-delivery decisions as they come before the council.

Who is the councillor linked to Baldur’s Gate 3?
The Green group includes a councillor who is also a voice actor and played eight characters in the video game Baldur’s Gate 3, according to the report.
That detail has added an unusual profile point to the party’s local success, although the election result itself remains the central political development.
It also illustrates how local councils can include councillors with diverse professional backgrounds. In Greenwich, the Greens’ expanded team now combines that mix of experiences with a much larger voting presence in the chamber.
What did Rhymes say about the campaign?
Rhymes said the party was “hugely proud” of the campaign that delivered the breakthrough, as reported by MyLondon. She said the Greens had built strongly on the single seat they held less than a year ago.
That language suggests the party sees the result not as a one-off protest vote but as a broader local advance. It also indicates that the Greens will now try to convert electoral momentum into consistent council performance.
How does this fit into Greenwich politics?
Greenwich has long been a Labour-controlled borough, so any shift in the opposition landscape is politically important. The Greens’ move from one seat to 13 changes not only their own standing but also the tone of debate inside the council.
The Conservatives losing opposition status also matters because it alters how Labour is likely to be scrutinised in the coming term. Instead of facing a familiar Conservative challenge, Labour will now have to contend with a larger Green group that may prioritise environmental issues, public services and local accountability.
Background of the development
The immediate background to this development is the full council election in Greenwich, where the Greens achieved a major breakthrough after first gaining a foothold through a Shooters Hill by-election last June. That by-election had left Tamasin Rhymes as the party’s sole councillor in the borough, but the full election transformed that position into a much larger group.
The wider context is a shift in local political momentum. A party that was previously represented by just one councillor has now become the official opposition, which is a substantial change in a borough’s political structure and in the way council business is likely to be contested.
Prediction for residents
For Greenwich residents, the most likely effect is a more active and visible opposition in the council chamber. That could mean more questions on council decisions, more pressure on Labour to explain policy choices and more attention to ward-level issues that might previously have received less scrutiny.
For voters who supported the Greens, the result raises expectations that the party will now use its larger presence to deliver the scrutiny it promised. For Labour, the new arrangement means it will have to manage stronger challenge from a group that now has both size and momentum.
