New Zealand’s government has proposed decriminalizing abortion and allowing women to choose a termination up to 20 weeks into a pregnancy.

Jacinda Ardern’s government issued details of a bill which would change abortion laws in force since 1977.

As things stand, a woman may only obtain an abortion if two doctors certify continued pregnancy would endanger her mental or physical health.

Ms Ardern has said she expects to vote on the bill to be “close”.

The legislation will go before parliament for the first time on Thursday.
