This is a broad question, but are there are any unified primary source assessments/collections of British decision and strategy-making in either the political (i.e. PM/Cabinet), military, or diplomatic thinking in the conflicts it fought after WWII (off the top of my head I'm thinking of Malaya, Aden, and Palestine, but I'm sure there are others.)

The closest US parallel I can think of would be something like the Pentagon Papers for Vietnam, although I know that since then the US (and other countries) have also inevitably done post-mortem studies on significant conflicts (e.g. the Israeli Winograd Commission after the Second Lebanon War.)

Was this done/does this exist for any of the above?

(edit, possibly ninja?): To be clear, I don't mean for all of these conflicts combined, although that would also work.

Is there anything like a British equivalent of the State Department's Foreign Relations of the United States series, for example?
