Plant id please if possible

Desi_in_London

Please see the pics below from a neighbourhood garden where I am trying to help someone identify the plant.
Looks like this was intentionally planted at some point , some vague attempt was made to train it along the wall , but it clearly wants to climb , sending up long shoots which basically grip on to tree branches above and grows into it.

The leaves are glossy , appear in little leaflet sets alternately along the branches. the branches are thorny - spikes of maybe 1-1.5 cm ( half inch). 
Never seen flowers according to her but her aspect is the same as mine ( ie shady courtyard) so that may be the reason. 

3 pictures attached , one of it growing along wall, ( wires at some stage) , and pics of cut off different ages of twigs/ growth with leaf habit shown. I've reduced size to upload pics so hopefully resolution remains ok. 



Any help appreciated.

Ha ha -- i had no idea that they tried to be climbers! I have only ever seen them as hedges/shrubs elsewhere -- thanks!

They aren't strictly speaking, but they can be used in the same way as they grow through other shrubs or planting.
They can also be trained as topiary, and look excellent like that, although you lose the flowering/berrying potential. 
They will grow in shade -I had one in a previous garden which never saw the sun, and still flowered/berried,  but that one may be producing stems which are reaching for light a bit.

@Fairygirl that is likely the case , it's her back wall which gets basically no sun at all. Thanks very much for your swift id !

She could try cutting it back to encourage a better growth habit. Difficult without seeing the whole area though, and some perform better than others. There's one or two which are more columnar than the others.
