[Foucault-L] Foucault, intelligibility, social movements

hi all,

i'm looking for places where foucault (and foucault scholarship) takes
on the question of 'social movements' and/or 'collective action' (or
'politics' more generally), especially with respect to the question of
intelligibility. in other words: i'm trying to figure out how social
movements become intelligible, and ideally find some nuanced thinkers
on this question.

so far, laclau and mouffe and the theory of 'hegemony' is as far as
i've gone, but laclau positions himself as a gramscian, not a
foucauldian. on this note, does anyone know of specific debates
between foucauldians and gramscians on these questions?

any guidance on these questions would be much appreciated.

cheers,
nick
