Argue deep Tory reforms will be old-fashioned still (13)
I believe the answer is:
'old-fashioned still' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'argue deep tory reforms' is the wordplay.
'reforms' indicates an anagram.
'arguedeeptory' is an anagram of 'DAGUERREOTYPE'.
'will be' is the link.
Can you help me to learn more?
(Other definitions for daguerreotype that I've seen before include "Eye up to regard (anag) - old photograph" , "Early form of photograph" , "Old photo" , "Shot in past" .)
