Continue the 'One in two out' regulatory rule : Broken
Where policymakers do need to introduce a new regulation, and where there is a cost to business when complying with that regulation, departments have to remove or modify existing regulation(s) to the value of £2 of savings for every £1 of cost imposed.

We have received a response from the Department of Business, Energy and Industrial Strategy, who have accepted that this program has not been in place since 2015. As such, this promise is broken.
