Had a shot at Richmond’s last position? (5)
I believe the answer is:
drank
'had a shot' is the definition.
(I've seen this in another clue)
'at richmond's last position?' is the wordplay.
'at' is a charade indicator (letters next to each other).
'last' indicates one should take the final letters.
'position?' becomes 'rank' (rank is a kind of position).
The last letter of 'richmond' is 'd'.
'd'+'rank' is 'DRANK'.
(Other definitions for drank that I've seen before include "took a shot perhaps?" , "knocked back" , "Consumed alcohol" , "Imbibed" , "took a drop" .)
