More thickset (8)

I believe the answer is:

squatter

(Other definitions for squatter that I've seen before include "Person occupying property without legal right" , "Less tall and slim" , "Unauthorised occupant" , "Illegal occupier of empty property" , "person in illegal occupation" .)

I've seen this clue in the Sydney Morning Herald.
