Asperula cyanchica

It certainly looks like A. cyanchica, although it's difficult to get a sense of scale. The corolla is usually under 5mm, and these look a little large but I am probably being deceived. One of the distinguishing features of this plant (which separates it from other woodruffs) is that the upper leaves, which are in whorls of 4, have 2 long and two short leaves. I can't quite see this in the photograph.
There is a rare subspecies (A.cyanchica ssp. occidentalis) which is worth watching out for. It differs from the common ssp. in having sessile flowers (and in some other aspects - see The Plant Crib).
