From all ive read about them I would say Ronnie was the one with most say in the end as British said after Frances died. Before that it was Reg . When Ronnie was away for a while on the lam then in jail Reggie and their other brother Charlie kept the money coming and thier business running smooth but when Ronnie got out it all went to f××k. Apparently it was Ronnie who goaded Reg to kill Jack the Hat telling him ive done mine(Ronnie had already killed Georgie Cornell) now you do yours. There was about 10 or 12 all year round members of the firm and a lot of hangers on. The one true gangster connected to them was Fred Foreman a stone gangster and killer
