Times breaking story on royal gossip (7)
I believe the answer is:
tattler
'gossip' is the definition.
(I've seen this before)
'times breaking story on royal' is the wordplay.
'times' becomes 'tt' (two abbreviations for time).
'breaking' is an insertion indicator.
'story' becomes 'tale' ('tale' can be a synonym of 'story'**).
'on' means one lot of letters go next to another.
'royal' becomes 'r' (abbreviation).
'tt' going within 'tale' is 'tattle'.
'tattle'+'r'='TATTLER'
(Other definitions for tattler that I've seen before include "gossip" , "Chatterer" , "One who gossips" .)
