In this ‘in conversation with,’ I talk to Peter Edwards, a solicitor who has just passed his 50 year mark working in mental health (and, since it became a ‘thing,’ mental capacity law), and who has had quite the most extraordinarily varied and significant impact in ways that you might not be aware of. The article that I mention which sets out some of the things that he has done is here, but we use the time to reflect on what has changed for the good, for the bad, and on the ways in which the law helps and hinders.
