It is well known that in a perfect graph, there exists a clique which intersects all maximum independent sets (stable set), as in the proof of weak perfect graph theorem. So I want to know is the stronger statement true: In a perfect graph, there exists a clique which intersects all maximal independent sets.
(A maximum indepedent set is the largest indepedent set. A maximal independent set is an indepedent set which not contained in any larger independent set.)
