Shifty way to move Liberal within Party (5)
I believe the answer is:
sidle
'shifty way to move' is the definition.
I can't tell whether this definition defines the answer.
'liberal within party' is the wordplay.
'liberal' becomes 'l' (abbreviation).
'within' indicates putting letters inside.
'party' becomes 'side' (eg a side or party in a contract).
'l' inserted within 'side' is 'SIDLE'.
Can you help me to learn more?
(Other definitions for sidle that I've seen before include "Slink, creep, sneak" , "Inch along" , "Walk obliquely" , "Isled (anag.)" , "Walk stealthily" .)
