I have submitted evidence to the Commons Women and Qualities Committee. I was going to do a quick summary but Legalfutures beat me to the punch and probably did a better job of it too. Lest anyone think I am being critical of the SRA, I am not: they acted quickly and well. I do think, though, there is probably a need to go further, and to keep this issue under review.
My evidence also includes a detailed analysis of how NDAs like the Zelda Perkins might give rise to a criminal offence and why some of the evidence given to the Committee revealed a less than satisfactory understanding of professional ethics. You can read it here.
