Bash in, perhaps, and drive away (6)
I believe the answer is:
banish
'drive away' is the definition.
(I've seen this before)
'bash in perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'bash'+'in'='bashin'
'bashin' is an anagram of 'BANISH'.
'and' is the link.
(Other definitions for banish that I've seen before include "Send away (as punishment)" , "Send (someone) away" , "Condemn to exile" , "Drive away, maybe from country" , "Exile in ash-bin" .)
