Levelling-up and Regeneration Bill

I am still a bit confused about this. The Bill says that some mayors taking on police and crime commissioner powers can take certain powers to themselves and others can take others, so you end up with a picture around the country where they have different powers in different places. That was my concern, not that there would be an inconsistency between police and crime commissioners and mayors. What I wanted to understand with the amendment was whether, if the powers of the police and crime commissioner are transferred to the mayor, they will all be transferred. We do not want a different picture around the country depending on which powers of the police and crime commissioner have been moved over.
