Civil Partnerships, Marriages and Deaths (Registration Etc.) Bill

I congratulate my hon. Friend on bringing forward this very important Bill, which I fully support. I am very impressed by his prescience in introducing this Bill a year before the Supreme Court decided that this was a very good idea. He mentioned the power in subsection (3) of the new clause to make “any other provision”. Will he detail what kind of provision that might be in that particular part of the clause?
