Why Board Independence Is Not Enough During a Corporate Turnaround

What’s Happening

Diageo chair Sir John Manzoni is reportedly looking to reshape the company’s board by recruiting non-executive directors with commercial experience in the drinks industry or drinks distribution.

The Financial Times reported on 21 July 2026 that Manzoni was seeking industry “heavyweights” as Diageo confronts a serious downturn in spirits demand. The report said the company’s 11-person board has only one non-executive director who has previously held a senior role at a spirits company. It also suggested that Manzoni wants directors with enough industry knowledge and standing to challenge new chief executive Sir Dave Lewis during an ambitious restructuring.

Reuters, reporting on the Financial Times story, said the concern was whether the existing board had sufficient industry insight to guide Lewis or recognise if the turnaround began moving too far. Diageo responded that the board already has relevant consumer experience and that Manzoni supports its existing directors while continuing to seek the right balance of skills and backgrounds.

The reported board changes are being considered as Lewis moves quickly to restructure the company. Reuters reported on 17 June that he had asked executives to reduce headcount and other costs as part of the overhaul. Reuters, 17 June 2026

The Financial Times has also reported that Lewis is changing aspects of Diageo’s strategy, including lowering prices on some brands and increasing investment in ready-to-drink products. The changes represent a significant test of assumptions that have shaped the company’s approach to premiumisation, brand investment and growth. Financial Times, 21 July 2026

Manzoni became chair in February 2025 after serving as a Diageo non-executive director. At the time of his appointment, the company highlighted his experience leading complex global organisations and his previous board experience at SABMiller. Diageo, 19 March 2024

Diageo’s published governance material places responsibility for board composition and succession within its nominations process. Manzoni’s 2025 chair’s statement also identified the appointment of the right chief executive, support for the leadership team and the restoration of consistent growth among the board’s immediate priorities.

"Independence is not enough when the board has to challenge a turnaround CEO"

What’s Being Said

The immediate discussion will focus on whether Diageo’s current directors have enough sector experience, who might be appointed and whether the reported search implies dissatisfaction with the existing board.

That framing is understandable. It also risks turning a significant governance question into a comparison of biographies.

Consumer experience, financial expertise and formal independence all matter. Yet turnaround conditions change the work a board is being asked to perform.

Directors are no longer overseeing a relatively stable strategy. They are assessing a sequence of connected decisions made quickly, under pressure and with incomplete evidence.

The question is whether the board collectively understands enough of the commercial system to challenge those decisions properly.

"Turnaround conditions change the work a board is being asked to perform"

What I’ve Noticed

Board independence gives directors permission to challenge. It does not automatically give them the confidence to know where challenge is needed.

That distinction becomes more important when a forceful new chief executive arrives with a clear mandate for change.

A turnaround CEO will often move faster than the organisation is accustomed to. Costs may be removed, leadership roles changed, investment priorities reset and long-held assumptions about customers, pricing or routes to market challenged.

Much of that urgency may be justified. Some of it may be overdue.

The board must still distinguish productive disruption from damage that will only become visible several reporting periods later.

That requires more than general commercial intelligence.

Directors need enough knowledge of customers, distribution economics, brand investment, pricing behaviour and operational dependencies to recognise which assumptions deserve closer attention.

Without that knowledge, challenge can remain technically correct but commercially shallow.

Management can answer every question and still leave the central risk untouched.

"A turnaround CEO will often move faster than the organisation is accustomed to"

What This Means

A board can be formally independent, experienced and conscientious, yet remain poorly equipped for the particular conditions facing the business.

Turnarounds expose that gap because the board’s contribution must become more specific.

During a stable period, broad experience can help directors test strategy, risk and performance. During a difficult transformation, the board must judge the relationship between decisions.

A pricing move may protect volume while weakening brand position. Cost removal may improve margins while reducing commercial capability. A distribution change may release working capital while damaging relationships that took years to build. A leadership restructure may improve pace while concentrating too much information and authority around a small number of executives.

These decisions cannot be assessed properly in isolation.

Sector expertise does not guarantee sound judgement. Familiarity creates blind spots of its own. A board populated entirely by industry veterans may become too attached to accepted practices or too confident in assumptions formed under different market conditions.

The requirement is not sector purity.

It is enough relevant knowledge, combined with sufficient independence, to interrogate the executive without either deferring to confidence or defending convention.

That balance becomes harder to establish once a turnaround has gathered momentum.

"The Pressure Test"

Pressure-test this:

Could the board identify the three assumptions within the current transformation plan that would cause the greatest commercial damage if management were confidently wrong?

Hesitation may not indicate weak governance.

It may show that the board’s composition and information environment were designed for a different phase of the company’s life.

The first response is not automatically to replace directors. It is to make the capability gap explicit and decide how it will be closed before momentum makes meaningful challenge harder.

Independence gives a board permission to challenge.

Expertise gives it the confidence to know what to challenge.

If this feels familiar, it is worth having the conversation before the numbers force it. Some leadership tensions are easier to resolve while they are still private.
