About 85% of abortions come about because of the failure of contraception. If this is the case, then the rule should be that abortion will be provided on demand but only if the woman agrees to be sterilised at the same time (or spayed). Given that the Pill is pretty well 100% effective if taken daily (which it usually isn't!) and the Mirena coil has had fewer failures than tubal ligation, I think the Dept. of Health needs to look seriously at why, in the 21st Century are women still getting pregnant "by accident".

As for the time limit, the usual one in France is 10 weeks but in the USA most abortions take place at 12 weeks by D&C, which is least likely to fail. The normal time limit needs to be set in accordance to the method normally used. If it were possible to bring about an abortion by chemical means within 28 days, then that should be the normal limit.
