### Clue: A revolutionary's supporting PR section of the Greens (9)
### Answer: SPINACHES 
 ### Explanation: Definition: Greens
 { [ A + CHE(Guevara, Marxist revolutionary) ] **placed below**( …'s supporting;is supporting, in a down clue) SPIN(PR;public relations practised by spin doctors) } + S(abbrev. for "section").
Could "section" in the clue be deemed redundant with the "…'S" already in it.
