Papa, in bother with Edward, took over (7)
I believe the answer is:
adopted
'took over' is the definition.
('adopt' can be a synonym of 'take over')
'papa in bother with edward' is the wordplay.
'papa' becomes 'p' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' indicates putting letters inside.
'bother with' becomes 'ado' (I've seen this in other clues).
'edward' becomes 'ted'.
'ado'+'ted'='adoted'
'p' put inside 'adoted' is 'ADOPTED'.
(Other definitions for adopted that I've seen before include "Borrowed" , "Taken as one's own" , "Took under one's wing" , "raised issue on behalf of others" , "Took into one's family" .)
