To Whom It May Concern:

This is a request under the Freedom of Information Act. I hereby request the following records:

Any and all files on Desmond Patrick Costello

Desmond Patrick Costello (31 January 1912 – 23 February 1964) was a New Zealand linguist, soldier, diplomat, university professor who was accused of being an agent for the Soviet GRU and of having sparked the first in a series of spy scandals in the 1960s which brought down the Macmillan government in the UK.

Costello's MI5 file was released to the public in April 2017, but it fails to settle the issue of his supposed treachery.

Please conduct a search of the Central Records System, including but not limited to the Electronic Surveillance (ELSUR) Indices, the Microphone Surveillance (MISUR) Indices, the Physical Surveillance (FISUR) Indices, and the Technical Surveillance (TESUR) Indices.

The requested documents will be made available to the general public, and this request is not being made for commercial purposes.

In the event that there are fees, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 20 business days, as the statute requires.
