YRP, the news article says that the pilot acknowledged the instruction to "go around" so knowing NATS, they wouldn't say that if the aircraft hadn't responded "Maroc****, going around".
My thoughts are that if you haven't been issued a landing clearance, you should never even brush the tarmac, let alone touch and go as a post or two alluded to earlier. That is for the cockpit to know exactly how low they can get and have that "decision height" even if told to expect a late landing clearance. I cannot even contemplate what would happen if a controller ignores such a major instruction.
For those that think it is fine to ignore ATC, I hope you aren't the next major news article that ends up being your fault after the investigation.
