When I go out, I see lots of people wearing masks. I also see medical people wearing masks when dealing with COVID-19 cases. Why is this? The BBC was unequivocal, at the start of this crisis, in stating that masks are not useful as a preventive measure against COVID-19.

Was the BBC wrong, or lying? I don't recall seeing/hearing any official retraction of the previously stated position.

You mean this:
https://www.bbc.com/news/av/health-51881555/coronavirus-do-face-masks-actually-work

Seems to explain when you need them and when not.

A confusing video giving mixed messages with so many ifs, maybes, in
generals, etc. But perhaps the biggest error is that it shows and talks
about those simple face masks worn by doctors, nurses, etc, when
carrying out minor procedures. It also misses the point that if you are
wearing a mask, it acts as a barrier between your hands and face when
you forget to /not/ wipe your face with your hand.

I've had a couple of unused P3 masks for a year, and have now made good
use of them on shopping trips. The point is they will remove coughed
particulates in the 0.3 to 10 micron range. That was one thing the BBC
video was very poor on; if someone coughs a few metres ahead of you, and
you walk through the "cloud" do you think you'd be better off wearing a
decent mask or not?

It's up to you.
