'home counties' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.

'revolutionary thinkers suppressing resistance' is the wordplay.
'revolutionary' is an anagram indicator.
'suppressing' suggests deleting specific letters (suppress can mean to conceal or hide).
'resistance' becomes 'r' (electronics abbreviation).
'thinkers' with 'r' taken out is 'thinkes'.
'thinkes' is an anagram of 'KENTISH'.

'from' is the link.
