Sinn Féin leader Mary Lou McDonald has asked for a "full, deliberative and frank debate" on the legislation to change Ireland's abortion laws but cautioned against filibustering.

The debate on the Health (Regulation of Termination of Pregnancy) Bill 2018 resumed this evening.

Ms McDonald said "this legislation will require very, very careful thought and deliberation".

She called for "a full, deliberative and frank debate. But I am appealing to colleagues not to abuse the rules and regulations and latitude of the Houses of the Oireachtas to delay, and delay and delay legislation which already carries the democratic imprimatur and approval of the Irish people."

She stressed the need for the legislation to allow transgender and binary people avail of the services.

"For some people these are new concepts and terms but these are very real human beings," she said.

The language of this bill needs to reflect the diversity of the society in which we live, Ms McDonald said, and she appealed for the inclusion of gender neutral language for transgender and non-binary people.

Solidarity/People Before Profit TD Mick Barry said the legislation is not without shortcomings and the issue of health and the three day period need to be looked at.

His party colleague Paul Murphy said his group would not be taking any other speaking opportunity on the second stage debate on the legislation as they are eager for it to progress.

He said they do not want to delay it given the precarious nature of the Government.

Mr Murphy also took issue with the legal issues surrounding transgender men and non-binary people.

He said that if "trans men and non-binary people" seek access to abortion there could be difficulties with the legislation as the definition provided in it uses the term 'woman'.

He suggested that this should be replaced with "pregnant person".

Independent TD Catherine Connolly said that it was essential to highlight that no woman takes a decision to terminate a pregnancy easily and that this bill was about providing a health service.

She added: "If we have learned anything from the cervical smear scandal and all the other scandals that have involved women, it is to trust women, give them maximum information, to empower them, to put them at the centre of every decision making process and with that we will have a much healthier society."

Independent TD for Kerry, Danny Healy-Rae, said the right to freedom of conscience is a fundamental right protected by the Irish constitution and the European Convention on Human Rights.

He said no person should be required by force of law to take innocent life and that Irish doctors, nurses and midwives went into their professions to protect life, not to take it.

He claimed that a poll of 900 GPs showed that 75% of them say they do not want to participate.

The Dáil debate on the legislation has been adjourned.
