Blitz the digestives and add the butter & condensed milk.
Add to a lined tray - doesn't have to be an oven one as it isnt going in the oven! & Press down.
Melt your 2 terrys chocolate oranges (save a few pieces for the top for decoration tho) and drizzle over the top and spread evenly.
Leave to set over night in the fridge - it is ok after a few hours but best overnight!
