Health and Social Care Bill (Programme) (No. 4)

On a point of order, Mr Deputy Speaker. I wonder whether I might seek your advice in relation to a declaration of interest. The hon. Member for Boston and Skegness (Mark Simmonds) has made two interventions on the private patient cap and has made a declaration of interest. He is a director of Circle, a private health care company. Is it your ruling that every Member must make such a declaration if they speak during the course of this debate?
