A push for abortion on demand right up to birth would have the same effect.
Which may well be why that is suddenly being funded (if what a PP states is accurate).
There has for many years been a fairly stable situation in Great Britain (excluding NI), where anti-abortionists agitate while most other people ignore them and treat the whole matter of abortion as settled.
It's very hard to effect change in that environment.
So the first step is to disrupt that stability by starting fights. Fights in either direction - never mind the detail as long as it's passionate and engaging and polarising.
This creates opportunities for those primed and ready to move in.
So I'm not at all surprised to hear of some unlooked-for campaigning for abortion on demand up to birth. The anti-abortionists need a Something to have their fight against, which isn't the fairly stable and well-supported current situation.
(Of course some actors will start fights on any issue; the Russian troll farms specialise in "slipping a knife into the cracks and wiggling". They interfered in both directions in black rights campaigning in the US:
