Is this a weed?

I had thought this was a rhododendron going mad but looking again the cross-section of the shoots is almost bamboo-like(?)
Growing 6ft plus and not overly-attractive - there was a rhododendron in front I think but you’ll see that’s gone woody and probably dead tbh
Any help appreciated!

Leycesteria formosa. It's actually an attractive shrub given the right treatment. This one needs the dead wood removed, and maybe weaker shoots also. Do not shorten the stronger shoots (as so many others do: if you have been shortening them, anyone else reading this, then *stop it*) as these will flower later, followed by berries.

Jasmine maybe?
