I am obliged to the noble Lord for his assistance, which is always welcome. I do not agree with the point made by the noble and learned Lord, Lord Goldsmith, regarding the breadth of the provision. This is a standard type of power contained in many Acts of Parliament to deal with consequential issues, such as those alluded to by the noble Lord, Lord Bassam. A very similar power can be found in the Scotland Act 1998, in the Northern Ireland Act 1998, in the Government of Wales Act 1998, and in the Legal Aid, Sentencing and Punishment of Offenders Act 2012—LASPO. All these statutory provisions have a similar consequential power for the same purpose, so this is not unique, exceptional or unusual.
