The register keeps a separate record of this client for every firm that files for it and every spelling of its name. All 2 of its records are shown together here.
These two are not added together. An organisation lobbying for itself reports its own spending, and the firms it retains report what they were paid; the rules ask the first to include the second, but filings do not always do so and a filing gives no way to tell. Each is shown as reported.
