Can't find the original thread but the central theme of today's demonstration is that undocumented migrants are not able to access services. I find it a bit rich that people here illegally expect this. The argument that relationships between Doctors/Nurses and patients is damaged is nonsense as it is the reception staff that ask for ID.
