Log into a Tory's daft predictions (9)
I believe the answer is:
astrology
'predictions' is the definition.
(astrology is used to make predictions)
'log into a tory's daft' is the wordplay.
'into' is an insertion indicator.
'daft' indicates an anagram.
'a'+'torys'='atorys'
'atorys' anagrammed gives 'astroy'.
'log' put within 'astroy' is 'ASTROLOGY'.
(Other definitions for astrology that I've seen before include "Star divination" , "Study of the influence of stars on character" , "It claims divination by the positions of the planets" , "The telling of fortunes through the movement of planets" , "Interpretation of star signs" .)
