I was first made aware of the concept of abortion safe zones or buffer zones, as they're sometimes called, in a borough that I used to live in, in West London, that introduced them in 2018. They were used, in that instance, to prevent the harassment of those seeking abortions, staff members, and members of the public. It was a first for the UK, and these safe zones proved to be effective, and so, in 2021, the safe zone was renewed.
