Constitutional Reform and Governance Bill

I note that my right hon. Friend has referred to the provisions in new schedule 1 that refer directly to Northern Ireland. From whom did the Government seek clearance or agreement for those extended exemptions? If it was just the Northern Ireland Executive, whose affairs are already safeguarded from freedom of information and other things anyway, why do the provisions of the new schedule extend to the Northern Ireland Assembly, Northern Ireland Departments and any Northern Ireland public authority?
