Write a law so a referendum must be held before the Equality Act can be scrapped

Background

We wish for a law to be created so that before any moves can be made to scrap the Equality Act, this must go to the public in the form of a referendum beforehand.

Additional details

The Equality Act forms the centrepiece of the Equalities landscape and framework in this country. This keeps us on a level playing field Equalities wise with other 21st century western democracies. A referendum will act as a fail safe in that this action could not happen without the approval (by a vote) from the general public.
