We have, due to trouble, to get rid of (4,3)
I believe the answer is:
weed out
'get rid of' is the definition.
(weeding out is a kind of getting rid of)
'we have due to trouble' is the wordplay.
'have' means one lot of letters go next to another.
'trouble' is an anagram indicator.
'due'+'to'='dueto'
'dueto' with letters rearranged gives 'edout'.
'we'+'edout'='WEED OUT'
'to' is the link.
(Other definitions for weed out that I've seen before include "Identify and get rid of" , "Remove unwanted elements" , "Eliminate" .)
