Boss to lead with article, followed by stories (3,6)
I believe the answer is:
top banana
'boss' is the definition.
(I've seen this before)
'to lead with article followed by stories' is the wordplay.
'lead' becomes 'pb' (Pb is the chemical symbol for lead).
'with' says to put letters next to each other.
'article' becomes 'an' (indefinite article).
'followed by' means one lot of letters go next to another.
'stories' becomes 'ana' (archaic term for anecdotes or gossip).
'to'+'pb'+'an'+'ana'='TOP BANANA'
(Other definitions for top banana that I've seen before include "leader" , "Best of the bunch!" , "organisation chief" , "Star entertainer" , "first on hand?" .)
