Aberdeen beach at dawn

I stayed with my son in Aberdeen last night. I walked down to the beach this morning, just before dawn, a short ten minute walk, and took quite a lot of photos.
What do you think my son has in common with our new P.M. Rishi Sunak?
Is it that they are both allegedly worth many, many millions of pounds?
Is it that they both own four luxurious houses?
Or does the extra give you a clue to the real answer!!!
