What a weird article. It talks as if abortion is illegal in the UK. It is not illegal.

I think it’s talking about at what point in the pregnancy abortion is allowed. I think most would agree that there is a point at which elective abortion should be off the table (e.g. would anybody argue for an abortion to be allowed the day before birth?). So the debate is about when that point is. A fair debate, but articles like this don’t help.
