UK to see changes in hunt (4,3)
I believe the answer is:
seek out
'hunt' is the definition.
(I've seen this before)
'uk to see changes' is the wordplay.
'changes' indicates an anagram.
'uk'+'to'+'see'='uktosee'
'uktosee' with letters rearranged gives 'SEEK OUT'.
'in' is the link.
(Other definitions for seek out that I've seen before include "Try to find" , "Look to find" , "hunt" , "Search for and find (something)" .)
