Port east of Verona transformed repeatedly (4,3,4)

I believe the answer is:

over and over

'repeatedly' is the definition.
(I've seen this before)

'port east of verona transformed' is the wordplay.
'port' becomes 'dover' (English port).
'east of' is a charade indicator (letters next to each other) (some letters go to the right of others).
'transformed' indicates anagramming the letters.
'verona' with letters rearranged gives 'overan'.
'dover' put after 'overan' is 'OVER AND OVER'.

(Another definition for over and over that I've seen is " Repeatedly".)

I've seen this clue in The Telegraph.
