Old PM touring a land, drunk on the road hither? (8)
I believe the answer is:
mandalay
'on the road hither?' is the definition.
(reference to Kipling poem Mandalay)
'old pm touring a land drunk' is the wordplay.
'old pm' becomes 'may' (Theresa May).
'touring' indicates putting letters inside (touring can mean going round).
'drunk' indicates an anagram.
'a'+'land'='aland'
'aland' is an anagram of 'ndala'.
'may' going around 'ndala' is 'MANDALAY'.
(Other definitions for mandalay that I've seen before include "work of Kipling" , "Asian city" , "You'll find me on the Irrawaddy" , "Myanmar city" , "C. Burma city, on Irrawaddy" .)
