How to Identify Veto Players Before a Major Regulatory Decision

Start with the decision, not the stakeholder list

Most veto-mapping exercises fail at the first step: teams begin with a list of familiar names rather than the specific decision in play. A veto player is defined by their relationship to a particular decision, not by their general seniority or profile. Before you draft a stakeholder map, write a single sentence describing the decision, the formal instrument that will carry it (a rule change, an authorisation, a no-objection, a designation), and the date by which it must be settled.

Once that is fixed, the veto players are the actors whose refusal, delay, or public dissent would force the decision to be withdrawn, materially altered, or rerun. That is a much smaller group than the list of interested parties.

Separate the three types of veto power

Veto power comes from three sources, and they behave differently.

Formal veto. Statutory or procedural authority to block. Think PRA non-objection on a Part VII transfer, an FCA change-in-control approval, a competition authority referral, or a supervisory college member with sign-off rights. These are visible but often misread: formal vetoes are rarely exercised outright. They are used to extract conditions.

Institutional veto. Actors whose objection triggers a process that effectively blocks. A Treasury Select Committee chair does not approve rules, but a hostile hearing can freeze one. An ECB Governing Council member, an FPC external member, a senior official at a peer regulator whose concerns must be reconciled: all sit here.

Reputational veto. Actors who cannot stop the decision but can make its cost unacceptable. Consumer groups with direct lines to ministers, a former regulator now writing in the FT, a whistleblower inside a competitor. These are the ones firms consistently underestimate.

Map each candidate against which type of power they hold. Combining them into one list is the most common analytical error.

Trace the decision path, not the org chart

Org charts tell you who signs. They do not tell you whose desk the paper crosses, who drafts the submission, who is consulted informally, or who has the ear of the decision-maker on the morning of the vote. For any significant regulatory decision, there are typically five to eight people inside the authority whose view shapes the outcome, and only one or two are named on the public-facing document.

Work backwards from the decision. Who drafts? Who reviews? Which committee sees it? Who briefs the chair? Which counterpart authorities are consulted, formally or by convention? Former officials, ex-secondees, and specialist counsel are the most reliable sources here. Trade body staff are useful but tend to over-index on the visible names.

Test for latent vetoes

A latent veto is a player who is not currently engaged but would be activated by a specific trigger: press coverage, a constituency MP's letter, a rival firm's complaint, a consumer harm case. Ask, for each candidate: what would have to happen for this person to move from passive to active? If the answer is plausible and within the timeframe of your decision, treat them as a live veto player.

This is where good intelligence work separates from checklist compliance. The veto that materialises three weeks before the decision is almost always a latent one that was visible earlier but not treated seriously.

Weight by cost of activation, not probability

A five percent chance of a veto that costs you the decision is more important than a fifty percent chance of a veto that costs you a fortnight. Score each player on two axes: probability of activation, and cost to you if they do activate. The high-cost, low-probability quadrant is where most firms are underprepared.

What good looks like

A credible veto map for a major regulatory decision fits on one page, names fewer than fifteen people or institutions, distinguishes the three types of power, and identifies for each the specific trigger that would move them from passive to active. It is refreshed at least monthly in the run-up to the decision, and after any material development.

Your next step

Take the most important regulatory decision on your book this year. Write the one-sentence definition. Then list the people who could stop it. If your list has more than fifteen names, you have not done the analysis. If it has fewer than five, you have not looked hard enough.
