You will find that the registered address is his sisters residence. As far as I can tell she no longer wants anything to do with him as the letters addressed to Robertson from the Inland Revenue are being returned. If only they'd look north of the Border, say Ayrshire!
Digging a bit deeper will reveal that the company secretary is a Giles C Michie which was alleged to be Robertsons pre-adoptive name. I am not an expert on these matters but I was under the impression that the managing director of a limited liability company could not also be the company secretary. Not sure how fast companies house works on issues such as this but someone fraudulently registering themselves in both positions is setting up a scam and they should be very interested in this information methinks.
I repeat again, I have no university degree and do not need to lie about having one. (inside joke)
