I find it very disturbing the way that so many of these people interlock.
In the case of Linda Riley, the profusion of very similarly named companies is highly suspicious to my mind.
When I was first self-employed I got badly ripped off by a man who did this. He wrote to me on one letterhead then changed it to another almost identical name. Managed to claim that my contract was with the original company which, of course, had now folded.
I'm not saying Linda Riley is running scams. What I'm saying is that Companies House should make the effort to investigate situations like this.
