Roused to manoeuvres round King’s royal emblem (5,4)
I believe the answer is:
tudor rose
'royal emblem' is the definition.
(emblem of the House of Tudor)
'roused to manoeuvres round king's' is the wordplay.
'manoeuvres' is an anagram indicator.
'round' means one lot of letters goes inside another.
'king' becomes 'R' (abbreviation for rex, king in Latin).
'roused'+'to'='rousedto'
'rousedto' with letters rearranged gives 'tudorose'.
'tudorose' enclosing 'r' is 'TUDOR ROSE'.
(Other definitions for tudor rose that I've seen before include "Emblem of Henry VIII" , "royal badge" , "heraldic emblem" , "floral design" , "hybrid flower" .)
