The search for a new First Minister of Scotland has started - the third in three years - after Humza Yousaf announced his resignation yesterday in an emotional speech.
Yousaf says he "underestimated" the hurt caused by his decision to scrap the SNP's power-sharing agreement with the Scottish Greens - a move that prompted two no-confidence votes.
The polls suggest there is something more fundamental going on - a belief that ministers here in Edinburgh are simply not delivering the basics, like a health service that works and schools with high standards, even though it is they and not ministers in Westminster, who are in charge of those policies.
Today's Nick Robinson spends the day in Holyrood reflecting on the fall out of another emotional resignation by another Scottish first minister.

The Today Debate is about taking a subject and pulling it apart with more time than we have in the morning.
Amid a significant backlog in crown courts in England and Wales and related problems in the system in Scotland and Northern Ireland, Today presenter Mishal Husain asks if justice delayed is justice denied?
Joining Mishal on the Today debate panel are Claire Waxman, the Independent Victims' Commissioner for London; Charlie Taylor; His Majesty’s Chief Inspector of Prisons for England and Wales; Joanna Hardy-Susskind, a barrister at Red Lion Chambers; Lord Falconer, Labour Peer and former Lord Chancellor and Secretary of State for Justice and Sir Max Hill, who was the director of Public Prosecutions for England and Wales until October last year.

When Theresa May was diagnosed with type 1 in her 50s, she told the consultant: "I'm too old. I can't be”. Lady May says she would also eat Jelly Babies when her blood sugar dropped during meetings.
The former Prime Minister has now chaired a parliamentary inquiry into the life-threatening consequences of having both type 1 diabetes and an eating disorder.
She speaks to Today's Justin Webb why a joined-up approach by the NHS is needed so that healthcare professionals are aware of the 'conflicting pressures' on people with type 1 and an eating disorder. She also discusses her experience while in government of managing her blood sugar levels.

The last of our Christmas guest editors is the CEO of the global biopharma company GSK, Dame Emma Walmsley.
She wanted her programme to look to the year ahead with optimism. In these highlights from her programme hear Dame Emma in conversation with the Archbishop of Canterbury Justin Welby, who urges politicians not to treat their opponents as enemies but as fellow human beings.
Dame Emma also speaks to the Health Minister for Singapore; visits Kew Gardens and she asks former guest editor and Nobel Laureate Sir Paul Nurse to discuss with a group of students, the scientific and technological advances they are most excited for in 2024.
Simon Jack interviews Dame Emma to end her programme and she chooses a special piece of music.

Professor Jason Arday is our latest Christmas guest editor.
This year he was appointed as one of Cambridge’s youngest ever professors. A significant accolade by any measure but even more so when you consider that Professor Arday was diagnosed with autism and global developmental delay aged just three and didn't learn to speak until he was eleven or read and write until he was eighteen.
He uses his programme to look at improving adult literacy and he speaks to the head of Universal Music UK about championing neurodiversity in the workplace.
Professor Arday also indulges his passion for 90s music with a discussion including Blur drummer Dave Rowntree and as a fan of a sharp suit, he champions the tailoring industry.

Andrew Malkinson is Today's latest Christmas guest editor. He spent 17 years in prison for a crime he didn't commit before being cleared in July.
He uses his programme to look at justice and how one can cope with being locked up unjustly. He speaks to John McCarthy, who was held hostage for more than five years in the 1980s.
While in prison, the world of astronomy and space offered Andrew a sense of release and sanctuary from the immediate confines of his daily experience and a way to expand his world. So as part of his guest edit, he visits Jodrell Bank observatory.
And he tells Today's Justin Webb about the months since his conviction was overturned and how he still feels anger.
