Given that these are the CAA's nominated examiners in question, the silence from the regulator is concerning if not altogether surprising. I read the entire report with increasing anger on behalf of Captain Lawson.
This also provides an interesting insight into the BALPA problems at VS, although their cosy relationship with management elsewhere is still an issue. It seems like the CC at Virgin were (are?) operating as an extension of management.
Fundamentally this highlights a major issue with training at VS. If they're deliberately failing and managing out perfectly good pilots that they don't like, it makes one wonder how many trainer's mates are being let through the process when they shouldn't be. Perhaps, like all the major changes needed in aviation, the answer will, one day, be written in blood.
