A complication to contend with (6)

I believe the answer is:

tangle

This clue is a double definition.

'a complication' is the first definition.
('tangle' can be a synonym of 'complication')

'contend with' is the second definition.
(thesaurus)

'to' is the link.

(Other definitions for tangle that I've seen before include "Enmesh, snarl up" , "Snarl or confused mass" , "Twist, snarl, knot" , "Snarl-up" , "Jumble" .)

I've seen this clue in the Evening Standard.
