Thinking about it a little more I don’t understand how Germany expects the police to be able to provide this information.
Which prison he gets assigned to will depend largely on prison availability at the time of conviction. We don’t know how long the trail is going to last, so there’s no way to know this information.
It just seems like everyone involved is trying to be as awkward as possible.
I just looked it up in German media.
So, the point of pressure was that a lot of British jails are overcrowded and the Manchester police replied as to the place as “metropolian London”, which includes a the 160% allocated Wandsworth jail. The German authories asked what specific jail so they’re sure that it’s not Wandsworth and the Manchester police just never replied anything to that.
Germany was asking for guarantees that the prisoner wouldn’t be send to an inhumane jail and the UK wouldn’t give a guarantee.
This is a normal process for Germany when it comes to non-EU countries.
