Its pretty much unrecognisable in its current condition - at first glance I would have said one of the Brooms or Jasmine nudiflorum, but the little tufts of leaves here and there belie those possibilities.

This pic is abit closer. Have a feeling it's had little white flowers on it. The tendrils are very long too.
Should I do anything too it,like cut it back ect.?? I have given it a good feed and weeded around it.

It looks like it might be a climber of some sort because stems are twined round each other, but as to what it is, without foliage, its hard to say. I would say cut it back, but without knowing what it is, that might be a risky manoeuvre. I see its potted, some of its poor condition might be because its potbound.

It's similar to a Jasmine I have but mine has dark pink flowers, Jasmine beesianum.

Frustrating - but the two twining stems might just be Bindweed growing with the plant (which could also have white flowers)?

they look one of the jasmines to me as they are looking 'woody' and bindweed doesn't go woody.

I think it is Jasmine officinale. A thug if not kept under control. Fast growing eventually reaches a height of 12m. I cut stems to the ground each year in autumn but leave a few to ensure I get flowers the following year. It has a heady perfume. The flowers are white. Common name is Common white jasmine.

Thankyou to all your input. It hasn't anything in with it. No bindweed. Potted as I have no ground to put it straight into. I potted it up about 5 years ago and I have a feeling that it was a jasmine as I was trying to cover a wall. It does have tiny white flowers on it when it blooms if I remember rightly. I will cut it back and see what happens . ?

Google Jasmine officinale and check if that is what you have. If it is cutting back the stems will result in no flowers next year. Leave one or two stems if you want flowers. It is often used to cover ugly sheds or outbuildings but keeping it in the pot will be the reason it has not grown more than it has done.

I don't think its J. officinale, the few leaves there are are wrong for that - if it is a Jasmine, more likely J. beesianum. To be honest, if its any kind of Jasmine, the fact its in a pot means it can't grow properly anyway, needs to be in the ground, although I realise you can't do that.
