Order Peter a taxi to drive from home (10)
I believe the answer is:
expatriate
'drive from home' is the definition.
'order peter a taxi' is the wordplay.
'order' indicates an anagram.
'peter'+'a'+'taxi'='peterataxi'
'peterataxi' with letters rearranged gives 'EXPATRIATE'.
'to' is the link.
(Other definitions for expatriate that I've seen before include "Brit abroad?" , "resident abroad" , "in exile" , "one based abroad?" , "foreigner?" .)
