Ampa Group has suspended chief executive Sarah Walker-Smith following a complaint, placing governance at one of the UK’s more closely watched legal and professional services groups under immediate scrutiny. The group, best known for its largest legal brand Shakespeare Martineau, has said no wrongdoing should be presumed while an independent third-party investigation is carried out.
Walker-Smith, a chartered accountant with more than 25 years’ leadership experience, has led Ampa since 2021 and is also identified by the group as its Group Chief Executive Officer and Chair.
Keith Spedding, chair of Ampa’s Members and Nominations Committee, confirmed the suspension and said the business was operating as usual while the investigation continues. The development matters because Ampa is not a single-office legal practice but a group structure containing Shakespeare Martineau, Mayo Wynne Baxter, Marrons, Lime Solicitors, Corclaim, Coadax and CSS Assure.
Practitioner consequence now sits less in the complaint itself, about which no findings have been made, and more in how a legal group demonstrates procedural control while protecting fairness to the individual and continuity for clients.
For law firm management, the immediate issue is whether governance documents, committee authority, internal communications and client reassurance processes are clear enough to withstand pressure when a senior executive is removed from active duties during an investigation.
The episode also highlights the growing complexity of leadership structures in legal services businesses that operate across multiple brands. Ampa says its board makes long-term strategic decisions for the group, while its executive team oversees the running of the business and brand boards are empowered to support individual brand growth.
That model can offer agility, but it also places a premium on careful separation between group governance, brand-level management and any internal investigation process.
Solicitors, barristers and in-house counsel advising professional services groups will recognise that the legal significance is not whether the complaint is eventually upheld, but how the organisation preserves due process while maintaining client confidence.
Suspension language must be precise, investigation terms should be documented, and any internal messaging must avoid drifting from process into implied fault.
Employment lawyers will also recognise the familiar risk: even where suspension is presented as procedural, the handling of the process can become as important as the underlying allegation.
The wider market will watch whether Shakespeare Martineau and Ampa’s other brands can keep leadership continuity intact while the investigation proceeds. Mayo Wynne Baxter, Marrons, Lime Solicitors, Corclaim, Coadax and CSS Assure are all part of a group whose public response now needs to reassure staff, clients and counterparties without prejudging the outcome.
Ampa Group and Shakespeare Martineau will now need to show that their governance framework can manage the investigation without creating avoidable employment, reputational or client-service risk.
