Investigative journalists can uncover undeclared or unlawful campaign finance by reconciling donations, spending, services and beneficial ownership. The work must begin with the law and reporting period in the relevant jurisdiction. A large donation, third-party campaign or business relationship may be legal and disclosed; irregularity requires evidence of a breached rule, false return or concealed source.
Define the legal framework and reporting unit
Identify the election, campaign period, candidate, party, non-party campaigner and regulator. Record donation limits, permissible donors, spending caps, reporting thresholds, deadlines, valuation rules and imprint requirements. Keep candidate spending separate from party and third-party spending where the law does.
The UK Electoral Commission’s guide to campaign material and spending explains that regulated activity can include advertising, unsolicited material, events, market research and transport, and that imprints identify who publishes material and on whose behalf. It also notes that enforcement responsibility varies, including police responsibility for candidate-spending offences.
Build the declared-money baseline
Download official donation, loan and spending returns; retain the original files and publication dates. Normalise donor and supplier names, addresses and company numbers. Reconcile totals to invoices, receipts, bank records or audited accounts where lawfully available.
Create a ledger for cash, loans, credit, discounts, donated services, venues, transport, staff time and digital advertising. Do not assume “free” support has no reportable value. Compare invoices with market rates and document the valuation method and uncertainty.
Trace donors and suppliers to beneficial owners
Search company registers, historical officers, ownership filings, insolvency records, procurement data and lobbying registers. Map family, directorship, shareholder and payment relationships without treating association as proof of coordination.
Our guide to tracing beneficial ownership provides a structured approach to layered entities, while our lobbying-oversight framework helps distinguish access from influence on a specific decision.
Reconcile digital and physical campaigning
Use platform advertising libraries, page-transparency records, archived websites, imprints, venue calendars, print quantities and supplier portfolios. Capture the advertiser, target audience, dates and spend range shown by each platform. Match creative material to invoices and the entity named in the return.
Seek evidence of coordinated messaging, shared staff, common suppliers or payments before combining third-party activity with a candidate or party. Similar slogans and timing may reflect public political alignment rather than legal coordination.
Handle allegations and source material carefully
Separate official filings, independently verified records, source claims and analytical inferences. Give affected parties precise questions and adequate time to respond. Malta News Online’s report on Maltese party accounts, debt and donor risk offers relevant local secondary reporting; its figures and legal implications should be checked against filed accounts and Malta’s applicable party-financing rules.
Document every discrepancy: missing invoice, late filing, donor mismatch, undervalued service or unexplained payment. Ask whether it is corrected, exempt, disputed or referred for investigation. Avoid publishing private donor data unlawfully or presenting a regulator referral as a finding of guilt.
Publish an auditable conclusion
Link each claim to a source, show calculations and state limitations. The strongest campaign-finance investigation does not equate opacity with illegality. It demonstrates the declared amount, the independently evidenced amount, the applicable rule and the unresolved difference—while preserving the right of everyone named to answer.
