Drive round Northern Ireland track (7)
I believe the answer is:
monitor
'track' is the definition.
(I've seen this before)
'drive round northern ireland' is the wordplay.
'drive' becomes 'motor' ('motor' can be a synonym of 'drive').
'round' indicates putting letters inside.
'northern ireland' becomes 'ni'.
'motor' placed around 'ni' is 'MONITOR'.
(Other definitions for monitor that I've seen before include "Keep track of" , "Supervise" , "Keep under surveillance" , "Person or device for observing and checking" , "Sort of lizard" .)
