Display is partly British owned (4)
I believe the answer is:
show
'display' is the definition.
('show' can be a synonym of 'display')
'partly british owned' is the wordplay.
'partly' indicates the answer is hidden within the clue.
'SHOW' can be found hidden inside 'british owned'.
'is' is the link.
(Other definitions for show that I've seen before include "Display or exhibition" , "Exhibit - present" , "Entertainment - guide" , "Point out - parade" , "Demonstrate or reveal" .)
