Bedlam as Charles gets round in (5)
I believe the answer is:
chaos
'bedlam' is the definition.
(I know that bedlam can be written as chaos)
'charles gets round in' is the wordplay.
'charles' becomes 'Chas' (shortened form).
'gets round' becomes 'o' (I've seen this in other clues).
'in' is an insertion indicator.
'chas' placed around 'o' is 'CHAOS'.
'as' is the link.
(Other definitions for chaos that I've seen before include "Pandemonium" , "A total shambles" , "disarray" , "Utter confusion" , "Anarchy" .)
