Hi all,
I have spoken with 9(2)(a)
 who is the co-editor of the NBR and is the journalist looking to
write the article.
He wishes to have more of a technical discussion about the report (rather than the report in a
broader context) and talk to the underlying analysis which led to the assumptions being
reported.
Kind regards,
9(2)(a)

from our Comms team received an enquiry from 9(2)(a)
, co-editor at the NBR, on the
3W work. I have asked our team to find out a bit more about what they wish to discuss, noting
that we agreed to pre-clear any media enquiries with DIA before we agreed to comment further.
I will forward the nature of the enquiry when I know more, but this is a heads up
Regards
