Sought by MPs, perhaps (4)
I believe the answer is:
awol
'sought by mps perhaps' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for awol that I've seen before include "On the lam" , "'Absent without permission, initially (4)'" , "Absent without permission, in short" , "Absent without leave (abbrev.)" , "Not present when supposed to be" .)
