Emperor (SPECIES?) type Dragonfly

This insect was found floating in a pond and is clearly an “emperor” type of dragonfly. The abdomen was brown/olive, becoming a brighter greenish where it joined the thorax. I wouldn't have given it a second thought except for the yellow ochre shading in the wings. My recollection of seeing emperors in the past was that they had clear wings. The length of the whole insect was about 7.7 cm. I understand that some Vagrant Emperor dragonflies have appeared this summer in Britain. A diagnostic feature of those is stated to be a yellowish colouring or of the wings where they join the thorax. This insect had clear wings where they join the thorax. Another but even rarer insect is stated to be the "Lesser Emperor" dragonfly and that does seem to have this yellow colouring of the wings (source: Brooks 1997). As this is an extremely rare insect in this country (first sighting in Britain in 1996) I would be glad of opinions!
