Government's Brexit White Paper (p52) includes a guarantee that the UK "is committed to membership of the European Convention on Human Rights". Will be incendiary to hard core Brexiteers who saw the ECHR as the next in line for UK to leave assets.publishing.service.gov.uk/government/upl…
Let's assume UK signs up to a post-Brexit deal with the EU which includes a guarantee that the UK will remain part of the ECHR.
That's binding in that it stands whilst the agreement does. That's the UK locked in, effectively.
That's because of the dissonance that the Tory part of the Bill of Rights Commission encountered when trying to figure out how to change the HRA
There is no mileage in changing the Human Rights Act to 'deal with' elements which bother some of its critics (Daily Mail, some Conservatives, Brexiteers), such as the bits which stop the UK deporting people to a real risk of torture.
