Badger or Fox?

In the last week or so my friend has a visitor to her back garden who likes digging.

Her back garden is small and the rear has an old thick and tall privet hedge and whatever it is has decided to dig a large hole under it. At first I thought it might have been a fox. Now that I have seen it I'm beginning to think it may be a badger. The hole is downward sloping and is about a metre in depth. It bends slightly to the left but appears to go nowhere. There have been several attempts at digging other holes but they are very small ones.

Her home is in a built up urban area. Many of the properties date from the forties onwards. Apart from hers, many of the back gardens are large and back onto each other. If it is a badger I wonder where it came from as it would have to cross several busy and dangerous road to get to the area.

    There are two other photographs following this post.

Does anyone have any idea what might be doing this. If it is badger is there a way of discouraging it. The garden is the size of a table cloth and my friend is afraid it might cause more damage.
