Here are some of the key points from today's questions:

• Scottish Tory leader Douglas Ross called for a judge-led inquiry following failings in the Emma Caldwell murder investigation
• Humza Yousaf accepted there were serious failures in the case and said a judge-led inquiry was something the Scottish government was exploring
• He also said he would meet Emma's mother Margaret Caldwell to discuss the case
• Scottish Labour leader Anas Sarwar said any inquiry would have to be led by someone from outside Scotland to be "truly independent"
• The first minister said there was a strong argument for anyone leading such an inquiry to be from outside Scotland

That's all from our live coverage of First Minister's Questions this week. Today's editor was Paul McLaren and the writers were Craig Hutchison and Catherine Lyst.

John Swinney calls for police to be fully transparent in their investigation into the death of Brian Low in Aberfeldy.

Mr Low was shot while walking his dog on the outskirts of the Perthshire town. His death was initially treated as not being suspicious but officers now say it was murder.

The SNP MSP asks if the FM recognises the "deep unease" in the community he represents.

Yousaf adds his condolences to the family and looks to reassure the community of Aberfeldy who are "rocked by this tragic incident".

The first minister says Police Scotland are taking this case extremely seriously and he says they are working around the clock on this murder investigation.

There have been questions asked in the media about the time between Brian Low's death and post-mortem examination and the opening of the investigation.

He says Swinney's suggestion of an increased police presence will be passed on.

The SNP's Emma Harper, who introduced a bill to address livestock worrying in Scotland that came into force in 2021, brings up the issue after new figures were released.

She says incidents are increasing and that stakeholders, including the NFUS and Land and Estates, had called for a change to the Outdoor Access Code to mandate that dogs are kept on leads in fields where livestock is present.

She asks if the government will make an amendment to the code as part of the upcoming Land Reform Bill.

The first minister says the government will continue to make dog owners aware of their responsibilities and would give consideration to changes being made to the code.

Tory MSP Murdo Fraser asks what action the Scottish government is taking to prevent convicted sex offenders from changing their identity.

The first minister explains this is a matter of public protection and all registered sex offenders are subject to sex offender notification requirements.

Any change of name must, by law, be reported to the police, Yousaf adds.

He says the UK government is working on legislative changes on name changes in their criminal justice bill and the Scottish government is studying the amendments to this which it has just received.

"We're very keen to align arrangements where possible."

Fraser asks how quickly the Scottish government will move to close a loophole in the law which allows individuals, whose convictions pre-dated the creation of the sex offenders register, to conceal their offending history by changing their names.

The first minister says he was extremely concerned at press reports about the case Fraser refers to and he adds he understands the public concern about these issues.

The first minister asks for the details of Gill's case and he puts on record his sympathies for all the losses that she has experienced.

Humza Yousaf says:"I'm more than happy to look into this case."

He highlights improvements in cancer care, although accepting the situation is still extremely challenging.

"We are seeing more and more people on both the 31-day and 62-day pathways."

He points to Rapid Cancer Diagnostic Services which are showing "really positive signs".

The Daily Record today reports, external on sisters Gill Gooding and Jo Thompson who both have a devastating breast cancer gene, but while one has had a double mastectomy to prevent the disease the other on the opposite side of the country faces a wait of at least 18 months.

Alex Cole-Hamilton begins by saying his thoughts are with Emma Caldwell's family and also agrees there should be a judge-led inquiry.

The Scottish Lib-Dem leader turns to an international study which shows Scotland has among the longest waits and poorest access to cancer treatment.

He tells the chamber about Gill, whose mum, dad, cousin, aunt and two grandparents have all died of cancer.

Her sister tested positive for a cancer gene and was given preventative surgery. Gill has been denied testing, but eventually tested positive too.

She has been told the surgery her sister received in Edinburgh is not available in Glasgow, Cole-Hamilton says.

He asks the first minister to look into her case and ensure that all patients, no matter where they live, have the highest quality of cancer care.

The Scottish Labour leader repeats the words of Emma's mother Margaret:- "Whatever a woman's job, status, addictions or vulnerabilities, it should never be used as a reason to ignore sexual violence or treat them as a second-class citizen."

Sarwar asks the FM how he will end the culture of prejudice and discrimination that denies justice to so many.

Yousaf says Mrs Caldwell is "absolutely right" and adds that there is a lot of work going on but also says the government has published a strategy to challenge men's demand for prostitution, which he says is a form of violence against women and girls.

He adds that there are plenty of lessons to learn.

Sarwar says there are many “troubling issues” with the Emma Caldwell case – misogyny, prejudice and a failure to listen to women coming forward with evidence.

He says that among the failings is a wider culture of Scottish institutions fighting for their reputations rather than being on the side of victims and seeking to find the truth.

He says the key breakthroughs were only possible because of the work and bravery of journalists investigating the leads which senior police officers had ignored and says they should not be subject to intimidation and harassment.

Scottish Labour leader Anas Sarwar also focuses on the Emma Caldwell case.

He says Iain Packer committed 19 rapes, sexual offences or assaults after Emma’s murder in 2005 – victims who could have been protected if Packer had been properly investigated.

He pushes the first minister on who would lead any potential inquiry – pointing out that during the time of the murder inquiry there have been five lord advocates and six chief constables.

He asks Yousaf if he agrees that for any inquiry or review to be truly independent it needs to be led by an individual separate from Scotland’s criminal justice system.

The first minister says the Scottish government needs to do more to tackle misogyny and violence against women.

He re-emphasises that there is a strong argument that any inquiry would be led from someone outside Scotland.

The Scottish Tory leader points out Emma Caldwell, her family and the other victims were "betrayed by what was one of Scotland's worst policing scandals".

Humza Yousaf agrees "there are lots of questions that demand an answer".

For the many women who have been failed by the justice system and police, it is important they get the answers they deserve, the FM says.

He says he will meet with Margaret Caldwell urgently, and make a statement urgently too.

The FM pays tribute to Emma's mother and the women who were tireless in their pursuit for justice.

"I really feel the first minister has to go further," says Ross.

"The failings by the police and the crown are absolutely crystal clear," he insists.

"It's utterly shocking that the response from the police was to launch a surveillance operation targetting the journalists and the whistleblowers."

The first minister agrees that is "incredibly worrying and incredibly concerning".

Yousaf agrees some of the allegations being made in relation to the police are shocking.

Douglas Ross returns to Margaret Caldwell's comments, through her lawyer, this morning where she says a judge-led public inquiry "is the very least my Emma, and the many women who spoke up, deserve".

The police who remain in the shadows have failed us for far too long, she said according to Ross.

The first minister needs to agree to a judge-led inquiry, insists Ross, and make sure the judge is from outwith Scotland.

Humza Yousaf repeats he does not rule out a public inquiry and agrees with the Scottish Tory leader on the possibility the judge would come out of Scotland.

"It's very firmly on the table," he reiterates. The ongoing legal process must be considered, he adds.

"I will meet with Margaret Caldwell."

Humza Yousaf begins by giving his condolences to Emma's family, friends and loved ones.

The first minister pays tribute to Emma's mother Margaret Caldwell and praises the "tenacity" of the reporters at the Sunday Mail and at BBC Scotland who exposed Iain Packer to try to seek out justice.

Yousaf accepts there were serious failures in this case and he will meet with Emma's mother Margaret Caldwell to examine and look at the case.

"A judge-led public inquiry is absolutely something we are exploring."

Two former sex workers who were picked up by Iain Packer say women needlessly suffered attacks after police failed to act on warnings that he was dangerous.

Iain Packer, 51, was found guilty of killing Emma Caldwell in Limefield Woods, Biggar, in April 2005.

He was also convicted of 11 rapes and multiple sexual assaults against 21 other women over a 26-year period.

Police Scotland has apologised and said victims did not get the justice they deserved from the first investigation.

Emma's family's lawyer, Aamer Anwar, has called for a judge-led public inquiry.

Douglas Ross begins by saying yesterday the killer of Emma Caldwell was finally brought to justice after 19 years.

The Scottish Conservative leader says, as well as her murder, Iain Packer was convicted of 33 offences against 22 women committed over three decades.

He should have been behind bars years ago, Ross adds.

He says Margaret Caldwell, speaking through lawyer Aamer Anwar, said they knew it was Packer in 2006 and she called for and independent public inquiry.

"Will Humza Yousaf take the opportunity today to immediately announce the establishment of a judge-led inquiry?"

The trial and eventual jailing of Emma Caldwell's killer Iain Packer has been dominating the news in Scotland.

Police have apologised for how the original murder inquiry was handled and for letting down Emma and other victims.

Emma's family said she had been failed by police due to a "toxic culture of misogyny and corruption" which left Packer free to rape and attack other women.

The Scottish government said it would consider holding a public inquiry into what went wrong with the original investigation and there's a strong possibility the issue will be raised at FMQs.

Earlier this week, the Scottish government's budget passed its final vote at Holyrood.
