By the time I make this post, you may well already have read about this through Facebook, Twitter, or wherever. It's rather startling, really, and there doesn't seem to be much question that this is a case of actual plagiarism, rather than the sort of attributed borrowing and reshaping of another's text that goes on in poetry.
I don't know Christian Ward, other than by seeing his poems in magazines, and as I write he is yet to make any sort of public response to what's happened. I'd sound a note or two of caution, though. Given that he's a widely published poet, it seems a very odd thing to do, firstly because he doesn't really need to, and secondly because he must have known that ripping off a relatively well-known poet like Helen Mort would be discovered very quickly. It must be a possibility, then, that this is someone using his name to cause trouble for him. Although that's probably even more depressing than the simple fact of what's happened.
I do know Helen Mort, who wrote the original poem, a little, and she's a very fine writer who doesn't deserve to have to deal with this sort of nonsense. I don't suppose it's much consolation to be considered a poet worth ripping off, or that she might get a little bit of extra publicity.
It did set me thinking, though. I've seen comments that Christian Ward (or 'Christian Ward', as we'll call him for now) might have attended a workshop with Helen, say, absorbed or copied down part or all of her poem there, then later quite innocently have thought it was his own. That doesn't sound very likely to me - in my experience, you do recognise your own writing, no matter how long it is since you've seen it, or how complicated its origins.
Except. I've posted before that I occasionally come across notes that I've made that seem to be based on a particular source, but which I can't place. Perhaps I have written them. I am certain in all cases that they haven't come from another poet, but I can never shake the nagging feeling that they're from some prose work I've read and largely forgotten.
What to do? Slow, patient revision and research seem to be the only answer - the multiplicity of sources available online these days makes it a problem that's only likely to grow.
