Repeated danger signal goes around the country (8)
I believe the answer is:
restated
'repeated' is the definition.
('restate' can be a synonym of 'repeat')
'danger signal goes around the country' is the wordplay.
'danger signal' becomes 'red' (red often signifies danger - eg a red alert).
'goes around' indicates putting letters inside.
'the country' becomes 'state' ('state' can be a synonym of 'country').
'red' enclosing 'state' is 'RESTATED'.
(Other definitions for restated that I've seen before include "Iterated" , "In other words" , "Didn't tell us anything new" , "Said again" , "Declared, not for the first time" .)
