And the 50% is profit. Obviously.
The reason they got special treatment was because of the speed. That was what the priority list was for - "establishes that presence on the high priority lane did not confer any advantage at the decision-making stage of the process", what you have linked me is exactly what I was just told you. The award wasn't unlawful, the govt did not report on the detail of the contracts within the time period required...that was unlawful, but a function of the process (again, the contracts were awarded outside the usual process so all the information wasn't gathered...the NAO conducted a full audit of the contracts, iirc, before the contract details were reported in the public database).
There are companies that made no upfront investment, ordering equipment from China without any understanding of what they are ordering, any relevant experience, and huge quantities fo PPE had to be destroyed because it was not fit for purpose and did not meet regulatory requirements. Most of the companies contracted had no experiece of dealing with medical equipment ever before. I personally know people who have experience in the industry and government passed them up for contracts in favour of the shitsters that were chosen.
And the fact that companies were treated the same when they were assessed doesn't alter the fact that being assessed sooner rather than later is a massive advantage.
