'Top People' correspondence consists of letters sent primarily from MPs and members of the public to Edward Heath, and occasionally representatives of local Conservative associations and other organisations, with replies drafted by Heath's Private Office on his behalf.

Heath received correspondence on a wide range of issues so unless the majority of the correspondence of any file is devoted to a single issue, the subject matter has not been listed.

The original alphabetical order in which the correspondence was filed by the Private Office has been maintained, although at points some letters may be alphabetically out of sequence.
