Spanish king also pursued new friend (9)
I believe the answer is:
ferdinand
'spanish king' is the definition.
(I've seen this before)
'also pursued new friend' is the wordplay.
'also' becomes 'and' (both can mean in addition).
'pursued' says to put letters next to each other.
'new' indicates anagramming the letters.
'friend' is an anagram of 'ferdin'.
'and' put after 'ferdin' is 'FERDINAND'.
(Other definitions for ferdinand that I've seen before include "Spanish king" , "He loved Miranda (Tempest)" , "29 9 [TEMPEST CHARACTER]" , "emperor" .)
