I select different queen, where Richard III lies (9)
I believe the answer is:
leicester
'where richard iii lies' is the definition.
(Richard III is buried in Leicester)
'i select different queen' is the wordplay.
'different' indicates anagramming the letters.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'i'+'select'='iselect'
'iselect' with letters rearranged gives 'leicest'.
'leicest'+'er'='LEICESTER'
(Other definitions for leicester that I've seen before include "Elizabeth the first's favourite" , "City, Robert Dudley" , "Sheep - cheese" , "City; orange cheese" , "London film premiere location" .)
