Presiding officer Alison Johnstone said there had been detailed considerations and members had noted the manner and spirit in which the proceedings had been conducted.

The bill will be back before the Scottish Parliament on Tuesday for the final stage 3 debate and vote.

MSPs are getting back to work on this the fourth and final day of the revisions to the assisted dying bill.

It’s thought they hope to get all the amendments voted on by mid-afternoon so they have the bill in its final form to consider it fully over the weekend.

Some are passionately for; others determinedly against and some still swither and could switch at the last moment.

Tuesday will see the final vote but before that there will no doubt be emotional speeches on this critical issue, particularly as all the tensions of these late-night sittings bubbles up.

It’s a cliche but it is on a knife edge.

It’s incredibly unusual for parliament for parliament to sit on a Friday.

Perhaps the last proper Friday sitting was when MSPs paid tribute to the late First Minister Donald Dewar in 2000.

Now, Friday is an ordinary working day for MSPs as they hold constituency surgeries and deal with correspondence.

A couple of disabled MSPs did point out that a Friday sitting in Edinburgh away from their home base did mean significant issues with having to re-arrange carers.

There’s also the impact on family life.

Late last night, the SNP MSP Christine Grahame questioned why the former Conservative leader Douglas Ross had a colleague read out a speech while he monitored proceedings remotely.

He intervened to say that he’d driven home to Moray to see his son for his 7th birthday and would then leave at 5am this morning to get back to Edinburgh.

Many employees face work-life balance issues but for MSPs this is all playing out rather publicly.

It is rare for MSPs to sit on Friday but they have agreed to this extra session as the debate was behind schedule.

If passed, the Assisted Dying for Terminally Ill Adults (Scotland) Bill, external would allow terminally ill, mentally competent adults to seek to end their lives.

Welcome back to our live coverage of MSPs debating Stage 3 amendments to the assisted dying bill.

MSPs will sit for the fourth day to debate amendments as the bill draws closer to its final vote.

After another marathon session lasting almost seven hours, the third day of voting on amendments to the assisted dying bill has now drawn to a close.

MSPS will be back in the chamber tomorrow - an unusual experience for them on a Friday - to continue the process in a bid to catch up with lost time.

Welcome back to our live coverage of MSPs debating Stage 3 amendments to the assisted dying bill.

This will be the third day that this stage of the bill is debated in the Holyrood chamber and members are already more than four hours behind schedule.

MSPs have agreed to sit on Friday in an attempt to get back on track.

If passed, the Assisted Dying for Terminally Ill Adults (Scotland) Bill, external would allow terminally ill, mentally competent adults to seek to end their lives.

That brings today's session at Holyrood - and our live page coverage - to an end.

MSPs will be back in the chamber to continue debating amendments to the assisted dying bill after First Minister's Questions tomorrow afternoon.

Join us again then.

MSPs vote by 101 votes to 19 that the Friday sitting should go ahead. There were three abstentions.

Graeme Dey MSP, who is the Minister for Parliamentary Business in the Scottish government, says sitting on Friday will provide some members with "challenges" - but the same would apply on Monday.

He says there are a limited number of sessions and days left to debate and vote on this bill.

Dey says the debate is already more than four hours behind schedule, and concluding on Friday could avoid further delays.

Several MSPs, including former First Minister Nicola Sturgeon, say returning on Friday may be unavoidable.

Sturgeon calls on the Parliamentary Bureau to take time overnight to review next week's timetable to make sure we don't end up in the same situation.

Independent MSP Jeremy Balfour calls into question the lack of notice given about members having to sit on Friday.

He calls for Friday morning's proposed session to be delayed until Monday.

Balfour says some members will not be able to attend on Friday, either because they have caring duties or they themselves require care.

The problem has arisen because the timeframe for this session has been repeatedly extended because it is over-running by several hours.

MSPs are going to have to come in on Friday to continue scrutiny of this bill.

It’s highly unusual, though not unprecedented, for Holyrood to sit on a Friday, which is generally considered to be a day for politicians to be in their constituencies.

One previous occasion that comes to mind was for the Motion of Condolence for Donald Dewar back in 2000.

A final vote on the law to allow terminally-ill adults to seek medical assistance to end their life is due to take place next Tuesday.

The Presiding Officer has to rule whether a bill is within the legislative competence of the Scottish Parliament when it is introduced.

That happened in this case as the overall bill relates to the devolved issue of health.

But some provisions within the legislation, including the regulation of drugs or medicines and employment rights are reserved to Westminster.

Since the very outset, Liam McArthur has been open that for the bill to be enacted, co-operation with Westminster would be required.

So it shouldn’t really have come as a surprise to anyone who was paying attention.

The Scottish government has been fairly “hands off” with this legislation as it is a member’s bill. But it has been liaising with the UK government to ensure that the will of the Scottish Parliament is respected if the bill passes.

UK ministers have confirmed their willingness to do what’s necessary in a letter to the Scottish affairs committee at Westminster.

This is one of the first times voices have been raised during this debate, which has been otherwise respectful.

The clashes between government ministers and Tory MSPs including Brian Whittle, Douglas Ross and Stephen Kerr sprang up in relation to the fact that the UK government must sign off on the use of lethal drugs for assisted dying in Scotland.

Parliamentarians have been given a free vote on assisted dying, meaning they are not whipped to cast their ballots along party lines.

Several MSPs have warned that if the bill becomes law it could face legal challenges on human rights grounds.

They are now questioning whether the bill is competent or not.

There is a clash about the legislative competence of the assisted dying bill.

First Minister John Swinney questions the competence and defends the role his government has played during consideration of the bill, while Tory MSP Brian Whittle expresses anger at the approach of the government.

Here's a reminder of what our political correspondent Lynsey Bews has said on the issue:

Many MSPs are concerned about the legal protections on offer for NHS staff. That includes ensuring there is adequate training in place for those who wish to participate in assisted dying, and allowing staff who conscientiously object to opt out without any detriment. But fairly recently it emerged that the Scottish government considers those aspects of the legislation to be beyond Holyrood's powers, and has tabled amendments to remove them.

Scottish and UK ministers have instead being discussing the use of something called a section 104 order - that would see the UK government legislate for these provisions at a later date.

Liam McArthur has described the issue over devolved powers as " fairly routine", and has sought to reassure MSPs "that the law they wish to see will be the law they get".

But some in the chamber are nervous about removing what they see as crucial elements of the bill, and leaving them in the hands of politicians at Westminster to sort out.

Indeed, a number of organisations representing medical staff have raised concerns, stating the move raises important questions about "transparency, accountability, and the robustness of the legislative process".

Westminster's Scottish Affairs Committee suggested a draft order could be published before the final vote at Holyrood next week - to give MSPs clarity on how legal protections for staff would be dealt with. But there is no time left to do that - and it's possible this issue could prove a major stumbling block for the bill.

As MSPs continue to make their way through discussing more than 300 amendments, it's worth remembering that several changes to the legislation have already been made since it was initially proposed.

In the chamber yesterday, MSPs voted to put a six-month prognosis requirement on people seeking help with assisted dying.

Also, the minimum age at which people can seek to end their life has been raised from 16 to 18.

And eligible people must be resident in Scotland for at least 12 months and registered with a Scottish GP.

These are all highly personal and moral issues and for that reason MSPs will be allowed a free vote on the issue, meaning they will not be whipped by their parties.

That vote is scheduled for next Tuesday and there is still a huge amount to be debated in the chamber between now and then.

Significant changes within that quickfire batch of votes includes one by Daniel Johnson which will mean the registered medical practitioner involved in the case must carry out their assessment in person and not virtually, having met the patient on more than one occasion.

And an amendment proposed by Douglas Ross to ensure that the range of palliative care options, including symptom management, pain relief, psychological and social support and end of life planning, must be discussed with the patient.

For the first time, one of Liam McArthur's amendments has not passed.

The amendment would have required the doctor to tell the patient that if they are provided with a substance to end their life, that it's up to the patient to decide when they use it.

The vote was a close one, 59 votes in favour to 60 against, with three abstentions.
