I find it disturbing that people don't accept the law and always, but always take these threads to the nth degree. Why does it have to be about taking itto the nth degree. Because there is so much more drama in that, isn't there. 
There is no research that shows that people choose to terminate after 24 weeks unless for medical reasons.
Of 189,931 abortions carried out in 2011, 146 were after 24 weeks. All of those were carried out in NHS hospitals rather indicating that they were for medical rather than personal reasons.
Some facts from the Department of Health.

The age-standardised abortion rate was 17.5 per 1,000 resident women aged 15-44, thesame as in 2010, but 2.3% higher than in 2001 (17.1) and more than double the rate of 8.0recorded in 1970. •
