On K Street and in Whitehall, the memo is not a deliverable — it is the deliverable. A one-pager that lands well shifts a regulator's mind. A two-pager that meanders dies on a chief of staff's desk. The craft is taught nowhere and assumed everywhere.
Why corporate memos fail the political reader
Most C-suite communications staff write memos for board members. Board members read in calm, in private, with time. The political reader — a Congressional staffer, a Whitehall private secretary, a Brussels desk officer — reads in transit, between meetings, on a phone. The memo must work in that condition or not at all.
That single shift in reading conditions dictates everything: length, structure, bolding discipline, opening sentence, choice of evidence. Adjust nothing and the memo is invisible. Adjust well and it shapes the conversation.
The structural rules that travel across capitals
1. The first sentence is the entire memo
Every reader in Washington and London is trained to read the first sentence and decide whether to keep going. That sentence must contain the ask, the stakes, and the actor — not the context, not the history, not the methodology.
Wrong: "Following the publication of the EU AI Act in 2024, the regulatory landscape for general-purpose AI systems has evolved significantly."
Right: "We are asking the Department to delay enforcement of section 53(b) by 90 days. The stakes are $400m of compliance investment by US firms."
2. One question per paragraph
A political reader does not re-read. Each paragraph must resolve one question and exit. Paragraphs that try to do two things lose both.
3. Bolding is a contract, not decoration
Bold text signals: "if you read nothing else, read this." If a memo has more than five bolded passages, the contract is broken. The reader skims the bolds, finds them meaningless, and trusts neither.
4. Evidence by proximity
In Washington, evidence comes from CBO scores, GAO reports, and named former officials. In London, from HMT consultations, NAO findings, and IfG analysis. In Brussels, from Commission impact assessments and ECA reports. Citing the wrong source signals that the writer is not from the building.
The two-step open
The best lobbying memos open with a two-step move that compresses three pages into thirty seconds: (1) state the ask plainly; (2) name the political cost of not granting it. Everything that follows is supporting material the reader may or may not need.
Example: "We are asking the FCC to clarify the application of Title II to AI-enabled customer service systems. Without clarification by Q3, three major US telcos will pause hiring on 800 customer service roles — a politically visible signal we do not believe Chairman X wishes to be associated with."
That is the entire memo, distilled. Everything else is annexes.
The corporate translation problem
The dominant failure mode of corporate public affairs teams is to import internal-deck language into political memos. Phrases like "synergies", "stakeholder alignment", "value creation" are not just stylistically off — they signal that the writer does not understand the reader's grammar.
The political reader's grammar is: who benefits, who suffers, who gets credit, who gets blamed. A memo that does not translate the corporate ask into that grammar will be filed, not actioned.
The brief test
A useful test before sending any memo: print it, read only the bolded passages and the first sentence of each paragraph. If those alone do not communicate the ask, the stakes, and the next step, the memo is not ready.
The discipline is teachable. The craft is acquired by repetition. Both should sit closer to the C-suite than they currently do.
