Liberal vote for keeping Conservative in charge (8)
I believe the answer is:
eclectic
'liberal' is the definition.
'vote for keeping conservative in charge' is the wordplay.
'vote for' becomes 'elect' (I've seen this before).
'keeping' means one lot of letters goes inside another.
'conservative' becomes 'c' (abbreviation commonly used in UK politics).
'in charge' becomes 'ic'.
'elect' enclosing 'c' is 'eclect'.
'eclect'+'ic'='ECLECTIC'
(Other definitions for eclectic that I've seen before include "Taking ideas from many places" , "All-embracing" , "Selecting from various styles" , "Drawing from various sources, as memory does" , "Given to picking and choosing" .)
