I don't think abortion is at risk. The UK is not America. It's a political hot potato there, whereas most British people don't see abortion as controversial. Neither do most MPs.
It would take a complete change of tack to get a law passed and I don't believe there's any appetite for a change. All the medical experts say the 24 week limit is there for good reasons, and they can easily - and heartbreakingly- illustrate what those reasons are
My SIL had an abortion just before the deadline, after discovering the foetus had a chromosomal abnormality. Had he survived birth he would have died in the first couple of years. My SIL and DB are both very religious and it was a terrible decision to make.
My brother was told that if his DW didn't have his support to end the pregnancy, her MH might never recover. Then their priest said it was OK when a foetus was so severely affected. My DB caved, though I know he still feels they made the wrong decision and SIL should have taken the pregnancy to term and accepted God's will going forward. Yet he's not the one who's a Catholic. Weird.
I find it hard to imagine my loving, ever kindly little DB trying to stop my SIL from having an abortion. Painful. But then he's always been a black and white sort of person.
