Press to set tea out after interval (6,6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
fourth estate
'press' is the definition.
(synonyms)
'set tea out after interval' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'after' says to put letters next to each other.
'interval' becomes 'fourth' (fourth is a kind of interval).
'set'+'tea'='settea'
'settea' is an anagram of 'estate'.
'estate' put after 'fourth' is 'FOURTH ESTATE'.
'to' acts as a link.
(Other definitions for fourth estate that I've seen before include "addition to three-car family?" , "Journalistic profession - press" .)
