I would expect details of the investigation to remain confidential at an early stage.
I note that the French have now stated publicly that they are pursuaded that it is a Russian action. And Corybyn has now adopted the May ultimatum to Russia of 13 March to the extent that the only possibilities are Russian state action or Russia losing control of at least part of its CW capability.
I would definitely want to know what the lessons learned are, in how to manage an event which may or may not be terrorism but which required significant specialst skill from various bodies (reginal police, central police, labs, NHS, military) - did co-ordination actually work properly?
Why do the timelines appear to omit the time the Skripals vivisted the grave? Have I missed something about this? Because that seems to be quite an omission, as there have been appeals for public to come forward with sightings to put together fuller timeline, and any known timings would assist with that.
I am rather left wondering if they do actually know a) where the poisonings occurred and b) how readily it might be spread around by those who have been in contact with it, and also c) what level dose - single or repeated - is required to produce illness or death (as that makes a difference to the importance of b))
