Just over a year ago, Humza Yousaf became Scotland’s sixth first minister.
He was seen as the continuity candidate when he was elected to succeed Nicola Sturgeon as SNP leader.
But after ending the Bute House Agreement which his predecessor had struck with the Scottish Greens, he is now fighting to save his political future.
When he was confirmed as Scotland’s first minister in March 2023, Mr Yousaf became the first ethnic minority leader of a devolved government and the first Muslim to lead a major UK party.
His father is originally from Pakistan and emigrated to Scotland with his family in the 1960s, while his mother was born into a South Asian family in Kenya. Mr Yousaf has often spoken of the racist abuse he has received.
He was educated at the Hutchesons’ Grammar private school in Glasgow, then studied politics at Glasgow University.
Mr Yousaf was elected as a list MSP for the Glasgow region in 2011, then was promoted to minister for Europe and international development a year later.
He became transport minister in 2016 after winning Glasgow Pollok from Labour, which made him the first ethnic minority candidate to win a constituency seat in the Scottish Parliament.
He faced criticism for the performance of ScotRail after Abellio took over the contract to run the rail franchise, which ultimately led to it being nationalised.
Mr Yousaf was promoted again in 2018 when Ms Sturgeon named him as the new justice secretary as part of a reshuffle of her cabinet team.
But his flagship hate crime bill was mired in controversy over fears that the new offence of “stirring up hatred” could have a major impact on freedom of speech.
Mr Yousaf was also criticised for tweeting about his “disgust” over a video supposedly showing Rangers players using sectarian language that quickly turned out to be fake.
And he dismissed concerns about the state of Scotland’s police buildings as “hyperbole” just hours before the ceiling collapsed at Broughty Ferry police station near Dundee. Mr Yousaf had recently moved to the town.
Within three weeks of becoming health secretary in May 2021, Mr Yousaf apologised for any “undue alarm” he had caused by wrongly claiming that 10 children had been hospitalised “because of Covid”.
He also famously fell off a knee scooter that he was using in the Scottish Parliament while recovering from a ruptured Achilles tendon that he had suffered while playing badminton.
When video of his tumble was tweeted by BBC Scotland political editor Glenn Campbell, Mr Yousaf replied: “If anyone else had fallen over while on crutches, a knee scooter, or in a wheelchair would your first instinct be to film it & tweet out?”
Mr Yousaf’s supporters pointed to achievements such as delivering the Queensferry Crossing on time and under budget while he had responsibility for transport, and falling crime figures while he was justice secretary.
Humza Yousef is expected to resign today following the fall-out between the Greens and SNP following the break-up of their coalition government
