like the Scottish law?
I may have got details of the law wrong. I remember it being in the press, and signing a petition about it on the number 10 website. That was just as the MP's expenses scandal arose, and it wasn't mentioned anywhere after that.
I wrote to my (lib dem) MP about it (having been asked to stop breastfeeding in a cafe; I didn't stop, and said I'd sue them for sexual discrimination, though of course haven't) but never received a response from him
