The BBC is free to support article (6)
I believe the answer is:
auntie
'the bbc' is the definition.
(I've seen this before)
'free to support article' is the wordplay.
'free' becomes 'untie' (I've seen this before).
'to support' says to put letters next to each other.
'article' becomes 'a' (indefinite article).
'untie' after 'a' is 'AUNTIE'.
'is' is the link.
(Other definitions for auntie that I've seen before include "BBC nickname" , "Relative (familiar)" , "Name for BBC" , "Kinswoman" , "Untie a relative" .)
