South London News (South London News) September 11, 2026— Liberal Democrat MP Sarah Olney has launched her campaign to secure the nomination to become the Liberal Democrats’ candidate for the upcoming 2028 London Mayoral election. As reported by Kumail Jaffer, Local Democracy Reporter for MyLondon, the Richmond Park representative formally announced her candidacy at an event in Southwark, setting out an intention to challenge the traditional Labour and Conservative dominance over City Hall.
As reported by Kumail Jaffer of MyLondon, Sarah Olney stated that
“this is going to be one of the most consequential mayoral elections we’ve had”.
Addressing supporters and media representatives, she argued that her party has a tangible pathway to broad electoral support. As reported by Kumail Jaffer of MyLondon, Sarah Olney stated that
“the Liberal Democrats have a real opportunity, if we run a bold and optimistic campaign, to really gather the kind of support that can actually provide a challenge to Labour. We can provide a program that Londoners all across the city will feel that they can vote for”.
Current polling figures present a formidable hurdle for the Liberal Democrats. Recent data from Savanta UK for the Mile End Institute indicates that Labour leads voter intentions at 33 per cent, with the Conservatives and Reform UK sitting on 18 per cent, the Greens on 17 per cent, and the Liberal Democrats trailing in single digits. In the 2024 mayoral contest, the Liberal Democrats finished a distant third, capturing 5.8 per cent of the vote. Acknowledging these numbers, Sarah Olney conceded that the party must actively expand its reach far beyond traditional geographic strongholds in South-West London.
To bridge this electoral gap, Sarah Olney announced plans to deploy an advanced digital engagement strategy across the capital. As reported by Kumail Jaffer of MyLondon, Sarah Olney explained her media approach by noting that “we need to look at our methods of campaigning, and really take this opportunity to form that message, to make it bolder, to make it sharper, to make it clearer, and to use, you know, all the methods that are available to us to make sure that we get that across”. She emphasized that this digital framework would be unlike anything “has never been seen before” in local mayoral contests, targeting London’s six million eligible voters directly.

What are Sarah Olney’s core policy criticisms of Sadiq Khan?
A central pillar of Sarah Olney’s emerging campaign focuses on direct policy attacks against incumbent Labour Mayor Sadiq Khan. Speaking on ITV’s Late Debate prior to her official launch, she characterized the current municipal administration as uninspired. As reported by regional party channels, Sarah Olney stated that
“I think that Sadiq Khan has been a disappointment as mayor – he is lacklustre and uninspiring. London needs a change of leadership”.
Housing policy emerged as a primary battleground during her campaign launch. The Richmond Park MP singled out housing delivery as the current administration’s primary vulnerability. As reported by Kumail Jaffer of MyLondon, Sarah Olney branded housing as Sir Sadiq Khan’s “most significant and visible failure” during his tenure at City Hall.
To counter this perceived failure, Sarah Olney outlined a strategy focused heavily on estate regeneration rather than sprawling greenfield developments. As reported by Kumail Jaffer of MyLondon, Sarah Olney stated that
“we’ve got some great examples in my own constituency where dilapidated housing has been replaced with new housing,”
adding that
“not only can you add more housing and more units, but you can also rebuild in an energy-efficient, accessible way that is designed to suit modern ways of life”.
She further noted that pursuing projects on both large and small scales across the capital would allow the city to “get things going quite quickly and really move forward at speed”.
Beyond housing, Sarah Olney targeted municipal infrastructure management and local policing provisions. Criticizing ongoing disputes over major transport links, she pledged to avoid protracted administrative disputes. As reported by Kumail Jaffer of MyLondon, Sarah Olney promised to prevent recurring infrastructure “sagas” like the indefinite closure of Hammersmith Bridge by consolidating all cross-river transit links under a single strategic authority. This proposed authority would also prioritize the delivery of delayed projects, including the proposed Canary Wharf to Rotherhithe crossing.
On public safety, Sarah Olney joined other political opponents in condemning recent operational changes enacted by the Metropolitan Police regarding station access. Highlighting reductions in front counter opening hours across various London boroughs, she noted that maintaining at least one accessible front counter per borough was a core 2024 manifesto pledge made by the incumbent Mayor. As reported by Kumail Jaffer of MyLondon, Sarah Olney stated that
“by breaking that promise, he’s really breaking a very important link between the police and the general public”.
Furthermore, addressing local economic vitality, Sarah Olney proposed structural changes to how City Hall interacts with commercial sectors. She asserted that her administration would operate as aggressively pro-business, arguing that
“we need to boost the economy at every level and get London moving again”.
As part of this platform, she committed to ensuring that any future Deputy Mayor for Business would be chosen directly through an independent consortium of business leaders rather than through direct mayoral appointment.
Despite launching this intensive mayoral campaign trail, Sarah Olney assured her local constituents that her legislative duties in Parliament remain fully prioritized. As reported by regional Liberal Democrat statements, Sarah Olney confirmed that
“I will, of course, continue to be the MP for Richmond Park throughout the selection campaign and the subsequent mayoral campaign. My commitment to the constituency remains undimmed”.
Background of the Development
The announcement by Sarah Olney marks an early escalation in the political maneuvering ahead of the May 2028 London Mayoral election. The position of Mayor of London has historically been dominated by the Labour Party and the Conservative Party since its establishment under the Greater London Authority Act 1999. Incumbent Labour Mayor Sadiq Khan secured a historic third consecutive term in office following the May 2024 mayoral election, defeating Conservative challenger Susan Hall.
The Liberal Democrats have traditionally maintained localized pockets of strength in outer London boroughs—such as Richmond upon Thames, Kingston upon Thames, and Sutton—but have struggled to translate these council-level victories into majorities in city-wide executive contests. In the 2024 mayoral race, the party’s candidate finished behind both Labour and the Conservatives, registering a single-digit vote share. Sarah Olney’s bid represents an early effort by the party organization to establish a profile, build digital infrastructure, and challenge the two-party monopoly well in advance of the official nomination window and polling day.
How This Development Can Affect London Voters and the Liberal Democrats
Sarah Olney’s formal entry into the mayoral race introduces a dynamic shift that could influence how urban policy debates are framed across the capital, directly impacting London voters, local businesses, and regional political parties.
For London voters, particularly those residing in outer London boroughs and centrist political spaces, Olney’s focus on housing estate regeneration and infrastructure management provides an alternative policy perspective to the traditional Labour-Conservative binary. If her proposed digital campaign successfully scales up, it could increase voter turnout and political engagement among demographics that typically feel unrepresented by the major parties. Her promise to streamline river crossings and establish independent business leadership councils may also appeal heavily to commercial operators and commuters frustrated by bureaucratic delays.
For the Liberal Democrats, this early candidacy carries both high risks and strategic rewards. Given their current single-digit standing in published opinion polls, committing substantial resources to a city-wide campaign requires careful financial and organizational balancing. However, by positioning Olney—a sitting Member of Parliament with a high national profile—at the forefront of the campaign, the party aims to elevate its overall brand identity across Greater London. This increased visibility could assist local candidates down the ballot in securing council and assembly seats, transforming a challenging mayoral run into a broader organizational growth strategy across the capital.
