MPs have voted in favour of measures to decriminalise women terminating their own pregnancies.

Labour MP Tonia Antoniazzi’s amendment to the Crime and Policing Bill was supported, with MPs voting 379 to 137, majority 242.

The Gower MP said it will remove the threat of “investigation, arrest, prosecution, or imprisonment” of any woman who acts in relation to her own pregnancy.

She told MPs she had been moved to advocate for a change in the law having seen women investigated by police over suspected illegal abortions.

Under current law in England and Wales, abortion is allowed up to the first 24 weeks of pregnancy – and beyond that in certain circumstances.

However, abortion is still considered a criminal offence under the Offences Against the Person Act 1861 and the Infant Life (Preservation) Act 1929 – and it has to be approved by two doctors.

The result of the vote has not become official law as of yet.

It has been added to the government’s flagship Crime and Policing Bill that is making its way through parliament, and will come law once that bill receives royal assent.

During the Bill’s report stage, Ms Antoniazzi assured her colleagues the current 24-week limit would remain and that abortions would still require the approval and signatures of two doctors.

The Labour MP also maintained that healthcare professionals “acting outside the law and abusive partners using violence or poisoning to end a pregnancy would still be criminalised, as they are now”.

On issues such as abortion, MPs usually have free votes, meaning they take their own view rather than deciding along party lines.

During a Westminster Hall debate earlier this month, justice minister Alex Davies-Jones said the Government is neutral on decriminalisation and that it is an issue for Parliament to decide upon.
