"Yellow-winged" darter.

Species other than Yellow-winged Darter can sometimes have extensive yellow in the wings (which it seems like you know, otherwise you wouldn't have suggested it might be a Common Darter).

The all black legs rule out both Common and Yellow-winged Darter, and female Yellow-winged Darters also have a continuous dark line along the side of the abdomen (which would just about be visible here). In other European species, except Red-veined, this line is broken into 'dashes'.

It's not that common to see Ruddy Darters with this much yellow in the wings, but it can sometimes be this extensive.

Darter

Thanks Roy,for sorting out the ID ,it can get quite confusing.

Confusion.

It would be a lot simple if variation like this didn't occur!

Field guides often over simplify things as well, concentrating only on the features that can normally be used to separate species. This is understandable though, because a lack of space prevents all possible variation being described, and most people using the guides will probably come across very few 'unusual' examples like this.
