A fascinating snapshot of Mrs T and UK intelligence based on her initial encounter with the Joint Intelligence Committee (JIC), which appears on the website of:
Number 10 Downing Street

Hat tip to Kings College War Studies Tweet @warstudies.

A very short explanation of the JIC:
..the Joint Intelligence Committee supported by the Joint Intelligence Organisation assesses the raw intelligence gathered by some of the Agencies and presents it to ministers to enable effective policy making.

Incidentally Annex A is the best explanation of intelligence work I know:http://www.cabinetoffice.gov.uk/site...vember2010.pdf

For US readers this is the closest officialdom will get to saying - someone like the London CIA Head of Station sits in the JIC meeting's opening part:
Also in attendance, as was normal, were representatives of the UK’s closest allies, who were present for the discussion of current intelligence and then withdrew.
The others are expected to be Australia, Canada and New Zealand.
