I seem to recall, that when the new shop next door applied for planning consent for alterations, it was intimated by the agent that they would not be selling alcoholic drinks in deference to the off licence/wine shop next door.
I don't know whether such a statement would effect the granting of permission, but they got it, and now compete with the old established Rose Hill wine shop (Vicky Wine).
If you check the planning applications round about mid summer, you will see reference to this.
