Subgroup (7)

I believe the answer is:
faction
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">subgroup</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for faction that I've seen before include "camp" , "Dissenting group within a larger one" , "Rebellious group" , "Small trouble-making group within a group" , "band" .)
