Search the Mandelson Government documents

At 2.30pm today, the Government published a series of documents relating to the appointment of Peter Mandelson as His Majesty’s Ambassador to Washington.

This is in the form of three PDF files, each with multiple messages, and about 1,500 pages in total. It’s not very easy to navigate through – we’ve created a simple search tool.

The tool breaks those large PDFs into individual message records where possible. Users can search the text, filter by sender, subject and date, and open both the extracted text and the relevant PDF page extract for each result.

Full details are below – here is the tool:


This was done very quickly with automated tools and should be seen as an aid to research, not an official republication or authoritative database. The source material is complex. Many documents are email chains, forwarded messages, scanned pages, redactions, WhatsApp transcripts or OCR text. That creates lots of limiations:

  • Some messages are easy to identify; others are ambiguous.
  • Some message boundaries may be imperfect.
  • Some sender, recipient, subject or date fields may be wrong or incomplete.
  • Some PDF page extracts may include more than the relevant message, or occasionally miss part of it.
  • OCR errors in the original text may affect search results.
  • Redactions in the Government publication remain redacted here.

The original PDFs should always be treated as the authoritative source. The extracted text and metadata are provided to make the documents easier to search and navigate.


The documents are Crown copyright and were published under the Open Government Licence.

    The search function does not seem to work. Every text search returns essentially every document in the database.
