Information on the number of regulated advice firms who have given up defined benefit (DB) pension transfer permissions - March 2020

I am seeking information on the number of regulated advice firms who have given up defined benefit (DB) pension transfer permissions. 
 
- I would like to know how many advice firms have given up permission to advise on pension transfers since 1 April 2019
- Please specify how many of these firms that have given up their transfer permissions were making use of these permissions before surrendering them, i.e. how many of these firms had advised on a DB transfer before 1 April.
