International law dose not exist. It is just a collection of treaties signed by different nations that they agree to. IE it is entirely contract law.

And given how little the UK has cared about such agreements. IE openly committing genocide. Against the Geneva convention treaty. Arresting protesters and abusing disabled people against the ECHR treaties.

There is absolutely no way parliament is going to consider any of them to outright override UKparlimentry sovereignty.

And when you remember our constitution literally applies the historical authority of the king. Being passed to parliament. Any agreement we sign. Is very much only down to the current majorities willingness to follow.

A point very important to remember given current polling for the next election.
