as I've said, the problem with the BBC article then goes on to present a scenario that isn't what was happening out there in the real world.
If you recall, mid September the Govt had a problem with the testing system breaking down. People were just being tested, no symptoms, apparently over-loading the system.
We know they were mass testing schools and universities.
So the premise that false positives is an issue, but actually it isn't because only people likely to have covid are being tested, is where the BBC have strayed beyond where they reasonably should, suggesting they have a narrative.
They have been testing up to 395,000 a day - you think 395k a day have COVID symptoms?

Here is the graph showing the number of PCR tests done.
Does that look in line with symptoms in the public?
