How will abolishing the non-dom tax regime work?

And finally, there is no guarantee in a general election year that all of this will happen.

What's more, an incoming new government may shelve the proposals completely or want to design their own version. 

And even if it were to happen, given the huge amount of work that would be required from HM Treasury to overhaul the current system, I would not be surprised if everything gets pushed back to 2026 at the earliest.
