From the Daily Mail:

The debate over abortion was reignited last night after it emerged that 50 babies survive botched terminations in Britain every year.
The figures are the first to show the true scale of a problem thought to have been confined to just a handful of babies.
Now some of the country’s leading doctors will investigate how so many survived to be born after just 22 weeks of pregnancy. Shockingly, some of the babies may have gone through more than one abortion. ..
