Pro-life MPs have called for reform of the abortion law in England and Wales after new statistics show that babies born at 23 weeks have a one in three chance of survival.

The 23-week survival rate in England and Wales was 23 per cent in 2010 and fell to 20 per cent in 2011, but has since risen since calling into question the current abortion limit of 24 weeks in England and Wales.

Figures from the Office for National Statistics (ONS) show that in 2014, 33 per cent of babies born at 23 weeks reached their first birthday. The chances of life for babies born at 24 weeks has also risen.
