I'm a little stuck... Click here to teach me more about this clue!

'extreme republican' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'counts least in revolution' is the wordplay.
'in revolution' indicates anagramming the letters.
'counts'+'least'='countsleast'
'countsleast' is an anagram of 'SANSCULOTTE'.

Can you help me to learn more?

(Another definition for sansculotte that I've seen is " Revolutionary".)

I've seen this clue in The Guardian.
