There has been a lot of talk about 'Operation Yellowhammer'. In January of this year, little was known about it. pjc50 wrote in an answer dated January 2019:
(Personally I think it's more likely that some kind of emergency will be declared at the point of Brexit resulting in the election being delayed, under the Civil Contingencies Act. A telephoto shot of a document headed "Operation Yellowhammer" supports this theory, but there are no details.)
In September of 2019 (over 9 months after the public had been aware of the term, given the quote above), Parliament voted for the release of the Yellowhammer documents. From the Guardian:
Dominic Grieve is now making his application for a standing order 24 debate. Here is the motion he is proposing.
Dominic Grieve is opening the debate on his standing order 24 motion that would force the publication of the government’s Operation Yellowhammer document and No 10’s private prorogation correspondence.
The motion they speak of has passed and the UK government has released a scanned document on titled 'Operation Yellowhammer'. It seems to be a mere 5-page summary with little text and small bulletpoints.
A senior journalist for the Sunday Times, Rosamund Urwin, tweeted:
What's different about the new Yellowhammer document that the government has just published compared with the one I got hold of last month? The heading. What did the version I had say? BASE SCENARIO Now what does the new one say? HMG Reasonable Worst Case Planning Assumptions
With that in mind, I'm wondering if there's any indication (in addition to the tweet above) if these are not the actual Yellowhammer documents or not the complete Yellowhammer documents. Is there any such indication or was the government only required to publish a summary and is the now released document that summary?
