Scruffy UK PM networking? (7)
I believe the answer is:
unkempt
'scruffy' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
(Other definitions for unkempt that I've seen before include "Uncombed and untidy" , "Not neatly combed" , "Not neat or cared for" , "Met punk looking neglected with matted hair" , "Rough and ragged" .)
