Hampshire,
United Kingdom 
This tree/shrub is in my son's garden of his new house. He would like to know what it is (and so would I).

The fruit looks like a tiny pear.

The fruit makes me think of a medlar, although I would expect the leaves to be a touch narrower.

Crabapple was my thought, but the leaves are too wide for that as well. No way of knowing till we see the whole thing plus bark and branch and preferably more leaves.

Many thanks for your thoughts, I will get him to take photos of the tree when he has moved in.

Not enough for me for ID purposes on this one - need to see the whole thing as well, plus branches and trunk.
