Yes it was taken indoors, but it is shinny leaves and it has little white 'buds' on it, steams very twisted, I thought of Ivy but as it is in the compose heap wondered why, sorry cannot get another photo, chap brought it up club this afternoon, he now gone home.
I hadn't noticed the buds! I googled briony and I think @josusa47 is right - black briony with extra shine from the camera flash. It turns out that the one I get is white briony.
Doncaster, South Yorkshire. Soil type: sandy, well-drained
It looks very much like bindweed which I have growing all over my garden. I pull it out of the hedges, after trying to cut it off at the bottom, especially if it is tangled round other desirable plants. Like ivy, it will lose its grip after a short time and it can be tugged free. However it is very difficult to eradicate.

Looks like Black Bryony to me ... the leaves of Black Bryony are glossy
See link below (the leaves in the top pic are bramble not Bryony) .... scroll down to How to Identify
