Vocal support for male dog around royal residence (8)
I believe the answer is:
balmoral
'royal residence' is the definition.
(I've seen this before)
'vocal support for male dog around' is the wordplay.
'vocal' becomes 'oral' (I've seen this before).
'support for' is a charade indicator (letters next to each other) (in a down clue, some letters \'support\' others).
'male' becomes 'm' (common abbreviation).
'dog' becomes 'lab' (short for labrador).
'around' says the letters should be written backwards.
'm'+'lab'='mlab'
'mlab' reversed gives 'balm'.
'oral' put after 'balm' is 'BALMORAL'.
(Other definitions for balmoral that I've seen before include "Scottish residence of the British royal family" , "Scottish holiday residence of British royals" , "British royal summer residence" , "Holiday residence in Scotland of British royal family" , "Queen's castle" .)
