Sarah Walker-Smith
Introduction
Sarah Walker-Smith is the former chief executive of Ampa Group, the “House of Brands” legal-services group whose portfolio includes national law firm Shakespeare Martineau, Mayo Wynne Baxter and Lime Solicitors, who was removed from her position and expelled from the group’s membership in October 2026 after an independent investigation into allegations concerning her conduct. Walker-Smith had led Ampa since its creation in 2021 and before that spent two years as chief executive of Shakespeare Martineau itself; she was one of the most visible woman leaders in the UK legal-services sector, a frequent writer and speaker on purpose-led leadership who had publicly argued that the notion of a “strongman” leader was outdated. The group has never disclosed what the allegations were, what the investigation found, or why the committee concluded that removal and expulsion were the appropriate outcomes — a silence that, according to RollOnFriday reporting, has left even senior staff and partners unable to learn what she did.
Background Information
Walker-Smith built her career across some of the UK’s best-known regional law firms. Before leading the Ampa Group she was chief executive of Shakespeare Martineau for two years, guiding it through the series of mergers that produced the enlarged firm, and previously she was chief strategy and operating officer at Browne Jacobson. She also held representative and non-executive roles, including six years on the board of governors at Nottingham Trent University. Ampa was her signature project: a consolidation model designed to move beyond traditional merger-by-absorption, in which brands such as Shakespeare Martineau, Mayo Wynne Baxter, Marrons, Lime Solicitors, Corclaim, Coadax and CSS Assure keep their autonomy while collaborating as a group. She described her work on LinkedIn as “strategy leadership, responsible business voice, growth, governance and purpose led change,” and had written that the best leaders “can be purposeful and even ruthless in pursuit of what is right, without losing their humanity.” She is a chartered accountant by training.
The Controversy or Incident That Led to Their Cancellation
Removed as CEO and expelled following an independent investigation. Ampa’s membership and nominations committee removed Walker-Smith from the CEO position and expelled her from the membership after considering the findings of an independent investigation into allegations concerning her conduct; the nature of the allegations and the findings have not been disclosed.
According to RollOnFriday, Walker-Smith had been on leave for several months after Ampa suspended her earlier in 2026 following a complaint. The process that ended her tenure was run by the group’s membership and nominations committee, chaired by Keith Spedding, which considered the findings of an independent investigation “carried out following allegations concerning Ampa Group CEO Sarah Walker-Smith.” Spedding announced the outcome in a statement: “Following that process, Sarah has been removed from her position as Ampa Group CEO and expelled from the membership. The expulsion decision is subject to a right of appeal. The investigation was conducted independently and in accordance with the group’s governance procedures.” The group simultaneously reassured clients and stakeholders that Ampa and its individual brands “continue to be led by our managing directors and are operating as normal with no impact on the services we provide to clients.”
RollOnFriday’s report framed the outcome more bluntly: the group “sacked its CEO after an independent investigation upheld allegations of wrongdoing,” while noting that most staff still had no idea what she had done. The publication quoted sources describing internal “chaos” as the group mounted a reorganization one insider characterized as “cleaning the slate following Sarah’s sacking,” and said a source told it that even senior staff had their enquiries “batted away”: “The partnership have been kept in the dark over why she was even suspended. We still don’t know why, just more vague promises of future details.” The Law Gazette confirmed the nature of the allegations had not been revealed and that Walker-Smith had yet to respond publicly to the announcement.
Public Reaction and Consequences
Within the UK legal press, the case drew attention less for the undisclosed allegations than for the governance process that ended the career of the sector’s most prominent “purpose-led” chief executive — and for the contrast between Ampa’s public reassurances and the internal account of a partnership left guessing. RollOnFriday reported that an anonymous commenter claiming knowledge of the process said Walker-Smith had been a full member, not an employee, suspended after a complaint, and that the six-month investigation had led her senior colleagues to conclude she should be dismissed as CEO and expelled from the membership; that account could not be verified from the group’s own statements. The group declined to say what she had done to “deserve her defenestration,” in RollOnFriday’s words. Walker-Smith exercised or preserved her right of appeal against the expulsion; no outcome of any appeal has been announced.
Current Status
Walker-Smith is no longer chief executive of Ampa Group and is expelled from its membership, subject to a right of appeal. The group continues to operate its brands under its managing directors while its leadership structure is rebuilt; RollOnFriday reported that a new “interim council” was running the group and, per its sources, “keeping everything secret still.” She has made no public statement responding to the removal or the allegations, and no regulatory or legal proceedings arising from the matter have been announced. Her removal closes the tenure of the person who led the group since its 2021 formation and through its growth into a multi-brand legal platform employing more than a thousand people.
Impact on Their Career/Life
Before the investigation, Walker-Smith’s professional identity was built on exactly the governance and culture credentials her removal has now contradicted: she wrote and spoke on leadership as a “responsible business voice,” sat on a university board of governors, and led a group whose entire pitch to member firms was collaborative, purpose-led management. The expulsion from Ampa’s membership is not a garden-leave departure but the group’s most severe available sanction, applied after a six-month independent process, and its public framing — removal plus expulsion, with the nature of the findings withheld — leaves her professional reputation defined by an allegation no one will describe. In the UK legal market, where she was a regular conference presence and commentator, the removal is a permanent line on her record: the chief executive who built Ampa and was expelled from it under investigation. Her right of appeal remains the only channel through which the outcome could change.
