Outcome of break taken about the middle of July (6)
I believe the answer is:
result
'outcome' is the definition.
(I know that outcome can be written as result)
'break taken about the middle of july' is the wordplay.
'break' becomes 'rest' (a rest is taking a break).
'taken about' means one lot of letters goes inside another.
'the middle of' indicates the central letters.
The centre of 'july' is 'ul'.
'rest' placed around 'ul' is 'RESULT'.
'of' is the link.
(Other definitions for result that I've seen before include "Ulster (anag) - outcome" , "Final outcome" , "Final score" , "End - issue" , "'Outcome, consequence (6)'" .)
