Break in journey by provost travelling round east (8)
I believe the answer is:
stopover
'break in journey' is the definition.
(I've seen this before)
'provost travelling round east' is the wordplay.
'travelling' indicates an anagram.
'round' is an insertion indicator.
'east' becomes 'e' (abbreviation).
'provost' anagrammed gives 'stopovr'.
'stopovr' enclosing 'e' is 'STOPOVER'.
'by' is the link.
(Other definitions for stopover that I've seen before include "Overnight stay" , "Stay (of just one night?)" , "that hotel can provide?" , "bed and breakfast?" , "Break in a journey" .)
