Possible red Kite

I noticed a seagull mobbing another large bird, flying in the distance, seen from my garden (Portslade Old Village). I took a few pics, but most of these were out of focus because of the distance as the camera had problems focusing. However, the one good picture revealed what might be a red kite. The shape of the tail looks right and the white markings underneath the wings and body colour also point to this being a possibility.

Not being an expert on this, I am keen for others to take a look. I have posted the images of my blog 24^th May, link below.

It would be great to know one way or another.
