Dear William

I look forward to hearing PHE's response.

In the meantime, while you wait with baited breath, this was Public Health Wales response back in November:


BTW, do you realise that you have submitted this FOI three times over two days?

Kind regards

No I didn’t know I had submitted three times.

I received the same info I received from the Welsh Health. I was asking for similar from PHE which is much harder to get.
