Back in February we commented on David Cameron's hint that he'd support lowering the time limit for abortion – a decision he'd based on a faulty set of statistics and, presumably, the notion of drumming up some votes from pro-forced pregnancy campaigners. Not that a mere time limit would be enough for them. Oh no. Some US-based anti-abortion campaigners are now asking for the Pill to be banned. Because it kills babies (no, I don't understand how a drug that prevents ovulation kills fertilised eggs either, but there you go. Pill = baby murder, apparently).

There isn't technically speaking a vote on dropping the abortion time limit from 24 weeks, but it might be an off-product of the government losing their bid to push through the Human Fertilisation and Embryology Bill, which also, naturally, troubles pro-lifers who believe embryos are complete human beings with rights equal to their mothers.

The good news today is that in a survey of 109 MPs carried out by the Guardian, 57 said they would reject any attempt to alter the law on abortion time limits. Which, scaled up, is promising. Discredited nutters like Tory MP Nadine Dorries ("Twenty Reasons for Twenty Weeks!") are going to come out with some new statistics and viral emails I'm sure, but the BMJ has just released figures which show that the survival rate of babies born at 22 and 23 weeks has not improved in 12 years, despite advances in technology and research. There's no justification for changing the law.
