Fairly recent desire to support Tyneside (6)
I believe the answer is:
newish
'fairly recent' is the definition.
(I've seen this before)
'desire to support tyneside' is the wordplay.
'desire' becomes 'wish' (wishing is a kind of desiring).
'to support' means one lot of letters go next to another (in a down clue, some letters hold others up).
'tyneside' becomes 'ne' (region in North East of England).
'wish' after 'ne' is 'NEWISH'.
(Other definitions for newish that I've seen before include "having not long been born" , "Fairly recent" , "Rather novel" , "hip, to some extent" , "Quite modern" .)
