Should the MI5/SS logo be mentioned in this article? I believe it is pre-1955 but have also read that it was used from the 1950's to 1970's. Any more information on this? — Preceding unsigned comment added by 77.96.24.33 (talk • contribs) 21:42, 21 January 2009

Plans to open the northern operations centre were reported by The Manchester Evening News in February 2005, and plans to open a permanent Scottish office in Glasgow were reported by The Scotsman in January of that year.

This seems like old news to me. I nominate deletion. — MaxEnt 16:13, 15 March 2018 (UTC)[reply]

What is the point of 'All employees of the service are bound by the Official Secrets Act'? It's the law, all of us in the UK are bound by it. 31.52.252.166 (talk) 20:42, 28 March 2019 (UTC)[reply]

Is anyone against stating this important fact in the lead? — Preceding unsigned comment added by 90.174.3.218 (talk) 21:25, 1 January 2020 (UTC)[reply]

It's probably a bit more nuanced than that. I think it would be better to sort out the section "MI5#Participation of MI5 Agents in Criminal Activity first - the lead is only a summary of the article. I also think one might need to be careful not to exaggerate what is known. For example, the recent "Third direction" tribunal makes very clear that MI5 might have the power to do some things, but this does not mean they are immune from prosecution. -- zzuuzz ^(talk) 22:05, 1 January 2020 (UTC)[reply]

The Guardian is reporting that Whitehall uses this title to refer to MI5. Should this, and also the organisation's involvement in the development of drone-supported covert surveillance technology, be included in the article? ~dom Kaos~ (talk) 10:54, 6 March 2021 (UTC)[reply]
