Union is newly reformed in a foolish way (8)

I believe the answer is:

unwisely

'in a foolish way' is the definition.
(I know this)

'union is newly reformed' is the wordplay.
'union' becomes 'U' (common abbreviation as in 'Trades Union Congress').
'reformed' indicates an anagram.
'is'+'newly'='isnewly'
'isnewly' with letters rearranged gives 'nwisely'.
'u'+'nwisely'='UNWISELY'

I've seen this clue in The Daily Express.
