Lead wayward assistant to city (8)
I believe the answer is:
adelaide
'city' is the definition.
(Adelaide is an example)
'lead wayward assistant' is the wordplay.
'wayward' indicates anagramming the letters.
'assistant' becomes 'aide' (aide is a kind of assistant).
'lead' with letters rearranged gives 'adel'.
'adel'+'aide'='ADELAIDE'
'to' is the link.
(Other definitions for adelaide that I've seen before include "Woman" , "cook turkey on the barbie here?" , "Lead aide to Oz" , "where there was recently a test" , "Australian capital" .)
