Labour resignation sets up pivotal contest
Control of Wandsworth Council could change hands following the resignation of Labour councillor Lizzy Dobres in Trinity. A by-election will be held in the coming weeks, with the result poised to determine who governs the borough for the remainder of the term. The council is currently led by the Conservatives as a minority administration, sustained through a confidence-and-supply agreement with Independent councillor Malcolm Grimston.
Ms Dobres stood down after four years representing Trinity, citing the requirements of a new role which prevents her from holding elected office. In a statement, she paid tribute to residents and colleagues, while explaining the circumstances that led to her departure.
22Serving as a councillor for Trinity has been one of the greatest privileges of my life, and stepping down is not a decision I ever wanted to make. I had every intention of serving my full term. However, after a prolonged period of uncertainty in my day job whilst pregnant, I have accepted a politically restricted role. That means I can’t serve as a councillor while working in this job.22
Fine margins in Trinity ward and at the Town Hall
Trinity elects two councillors. At the most recent borough elections in May, former Labour councillor Jack Mayorcas lost his seat to Conservative councillor Kirsten Botting by 64 votes, while Ms Dobres retained hers by 195 votes. Those narrow results underscore how competitive the ward has become, and help explain why this by-election carries borough-wide significance.
The council chamber remains finely balanced. The Conservatives hold 29 seats, Labour has 28, and there is one Independent. Overall control requires 30 seats. Since the elections, the Conservatives have governed with the support of Cllr Grimston on key votes such as the annual budget and any motions of no confidence.
| Group | Current seats | After a Conservative win | After a Labour hold |
|---|---|---|---|
| Conservative | 29 | 30+ (two-seat working majority cited) | 29 |
| Labour | 28 | 27 | 28 |
| Independent | 1 | 1 | 1 |
What is at stake for residents
With the administration presently reliant on an agreement with the Independent councillor, the by-election offers the Conservatives a route to secure a stable majority. Should they win in Trinity, they would be able to form an administration without depending on external support. If Labour retains the seat, the existing minority set-up would continue.
While the candidates and poll date are yet to be confirmed, the outcome will shape the political direction at Wandsworth Town Hall and could influence how swiftly the council can advance its programme. Majority control typically affects:
- Appointment of the council leader and cabinet, and distribution of committee chairs.
- Passage of the annual budget and setting of spending priorities.
- Decision-making timelines on key policies and long-term planning.
How we got here
The Conservatives increased their representation by seven seats compared with 2022, reaching 29. Labour fell by seven to 28. With neither side reaching the 30-seat threshold, the Conservatives struck a confidence and supply arrangement with Cllr Grimston to enable the council to function, explicitly covering vital votes such as the budget and any no-confidence motions.
Trinity’s recent voting history suggests the by-election will be closely fought. The previous contests D decided by margins of 64 and 195 votes D indicate that turnout and local campaigning could be decisive. For residents, the immediate practical effect is continuity of representation pending the vote, followed by a rapid return to the polls to fill the vacancy.
Next steps
The council will now move to arrange the by-election in Trinity in the coming weeks. Parties are expected to confirm their candidates shortly. Until then, the authority continues to operate under the current arrangements, with the administration reliant on support from the Independent councillor on critical motions.
