Secretaries of State, previously and just now, have failed to answer the question from the Plaid Cymru leader, Liz Saville Roberts, on this, so I will have another go.

Will the proposed British Bill of Rights uphold that by enshrining the right to self-determination for the peoples of Wales, Scotland, England and Northern Ireland?
