UFO Flying Over The London Eye, City of London, U.K. 21/06/2014

UFO is spotted flying very close to the London Eye. It kept hovering high above and slowly drifting back and forth, it then started to go down at an angle and just disappeared. I've never seen something like this, especially in the City of London. It was a Friday night around 11pm.  I was out cycling last night and sat down to relax and watch teenagers make a fool of themselves ahah a few of them were drunk face out on the floor... silly. 
Anyway, I recorded this on my iPhone and rendered it in a lossless format and due to that, I tried keeping it short as possible due to file size. Anyway, have fun with it. It's my first sight of an unidentified flying object.
