3 bright orbs observed for 8 -10 minutes

Sighting in Milton Keynes, Buckinghamshire, England, UK.
Whilst walking home just after midnight I observed some lights in the sky to the West. Due to the number of street lights where I was I walked towards a retail park where it was a little darker to get a better view. I observed a bright light in the sky which illuminated the surround clouds. Its altitude did not change it was not a comet or meteorite in the atmosphere. There was 3 objects which circled around each other, at times their altitude went a little higher and they made a C shape at one point, was very bright. I managed to film but as this totally caught me by surprise and I am not use to recoding much on my phone especially at night I did not make full use of the zoom feature. I recorded a 5 minute video 2x zoom but too large to upload its nearly 700MB and took some photos which have attached. I did not observe any noise from the distance I was from them which I estimate to be 4-5kms.
I am trying to keep anonymous if you want the video email me.
