Well that is part of our problem in the UK that we have a really pathetic press that thinks news is just personality politics. And maybe that schools need to put more effort into teaching things like which political or human righst groups the UK is part of. I suspect many of us dont even know this within the UK.
My understanding is pretty sketchy but if you can trust AI:
The UK remains linked to the European Court of Human Rights (ECtHR) because it is a member of the Council of Europe and a signatory to the European Convention on Human Rights (ECHR), which is a separate treaty from the EU. While Brexit removed the UK from the EU legal order, the ECHR still binds the UK to uphold fundamental rights, with the Human Rights Act 1998 allowing these rights to be enforced in UK courts.
The Council of Europe (CoE) is the continent’s leading human rights organisation, founded in 1949 and based in Strasbourg, France. Comprising 46 member states, its primary purpose is to uphold and promote human rights, democracy, and the rule of law across Europe, notably overseeing the European Court of Human Rights.
Decisions in the Council of Europe (CoE), a distinct body from the EU focused on human rights and democracy, are primarily reached by the Committee of Ministers, which constitutes member states' foreign ministers or their permanent representatives. Decisions are typically made through consensus, but some areas may require unanimity or a qualified majority

Edited to add which I have only just realised is that, or will this decision then be the guidelines for the European Court of Human Rights/
