Follow from the start of exciting news story's unexpected elements (5)
I believe the answer is:
ensue
'follow from' is the definition.
(I've seen this in another clue)
'start of exciting news story's unexpected elements' is the wordplay.
'start of' says to take the initial letters.
The first letters of 'exciting news storys unexpected elements' is 'ENSUE'.
'the' is the link.
(Other definitions for ensue that I've seen before include "Happen or come about as consequence" , "Cultivate plants/vegetables" , "Happen afterwards as a result" , "Come to pass" , "Occur afterwards" .)
