Lots of organisations are working hard in this space and we'll list them here as they get in touch.  However one organisation that has done a phenomenal amount of work specifically on local government bodies is the Local Government Association. They have produced a portal specifically devoted to supply chain transparency that you can see here:

They have also been very helpful in providing links to statements that our bots had not found yet, and it is with thanks that we've added them to the map. They will show on the map after the usual automated checks.
