Here Livingstone found father in main road, car being tailed (6)
I believe the answer is:
africa
'here livingstone' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'father in main road car being tailed' is the wordplay.
'father' becomes 'fr'.
'in' is an insertion indicator.
'main road' becomes 'ai' (resembles A1, major UK road).
'being tailed' means to remove the last letter (to tail something can mean to remove its end).
'fr' inserted inside 'ai' is 'afri'.
'car' with its final letter removed is 'ca'.
'afri'+'ca'='AFRICA'
'found' is the link.
(Other definitions for africa that I've seen before include "Continent (6)" , "If a car could go to this continent" , "Continent in the Southern hemisphere" , "The dark continent" , "Out of . . . . . . (film) (6)" .)
