Explosive redtop to send overseas (6)
I believe the answer is:
deport
'send overseas' is the definition.
I can't judge whether this defines the answer.
'explosive redtop' is the wordplay.
'explosive' indicates an anagram.
'redtop' with letters rearranged gives 'DEPORT'.
'to' is the link.
Can you help me to learn more?
(Other definitions for deport that I've seen before include "Expel to another country" , "Expel unwanted person from country" , "Expel as an undesirable alien" , "Send home" , "Exile" .)
