Current queen and various characters in one majestic residence (7,6)
I believe the answer is:
windsor castle
'current queen and various characters' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'one majestic residence' is the wordplay.
'one majestic' becomes 'windsor' (I am not sure about this - if you are sure you should believe this answer much more).
'residence' becomes 'castle' (castle is a kind of residence).
'windsor'+'castle'='WINDSOR CASTLE'
'in' is the link.
Can you help me to learn more?
(Other definitions for windsor castle that I've seen before include "Royal residence" , "palace" , "royal house" , "Queen's residence" .)
