White stork?

Hi all

I live in Stoke on Trent, around 2 weeks ago I noticed a huge bird from my living room window. The images are not very clear as i didn't have much chance to get to my phone. The bird made the gulls look tiny and they seemed to be swooping at it. It went in a straight line across then circled a few times hardly moving its wings (which were huge) I could also see feet dangling down, they were very visible but unfortunately you cannot see on the images. I cant't find anything in the bird book i have that looks remotely like it and i've also put the image into bird identifier app and it says unknown when i put my location in but oriental stork if i leave my location off.

Does anyone know what this is?

Thanks
