Algeria's new royal emblems (7)
I believe the answer is:
regalia
'royal emblems' is the definition.
(I've seen this in another clue)
'algeria's new' is the wordplay.
'new' indicates an anagram.
'algeria' with letters rearranged gives 'REGALIA'.
(Other definitions for regalia that I've seen before include "Ceremonial emblems of high office" , "Orb and sceptre, for example" , "ceremonial gear" , "Orb and sceptre etc" , "Emblems of royalty used at coronations" .)
