Scrounger, one claiming to pocket pounds (7)
I believe the answer is:
blagger
'scrounger' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for blagger that I've seen before include "One who obtains something by persuasion or guile" , "Obtain something by persuasion or guile" , "Grab leg of a scrounger" .)
