If it's a crime to share a draft of a law, you're no longer dealing with a liberal democracy, but a Saudi-style shithole, and it's time for that country to remove its government.
The Official Secrets Act must be signed by you and pertains to 'official secrets' you may become party to as a servant of the Crown. It is not illegal to share this as a common civilian. Whether it is safe to do so is another matter entirely.
that's not true at all, Section 5 applies to everyone, and deals with passing on secrets you've obtained from people who have signed the act.
That said, and IANAL, this document is not covered because of 5(2) - there's no reasonable grounds for believing that releasing this document is damaging to national security. It's a draft, so does not describe any measures currently in effect, and the draft will be made public in a few days when it is submitted to parliament, before it has any effect.
Dangerous and wrong advice. I already knew what the other posters replied with. I was looking for more specific opinions about whether it would be safe to post this link on a Facebook type platform
