Portugal has experienced unstable political times, but Scotland is no exception.

Just over a year ago, Nicola Sturgeon stepped down as First Minister after eight years in office.

As usual, there were no elections. Her successor came from within the Scottish National Party: Humza Yousaf.

But Yousaf was only prime minister for about a year. He also resigned on Monday.

"I've come to the conclusion that repairing the relationship in this political divide can only be done with someone else at the helm," he said.

The former prime minister was referring to the end of the government agreement with the Greens.

There have been tensions between the partners, with the high point coming from the government's backtracking on climate change targets. The government has admitted that it will not meet some of the gas emission reduction targets it had guaranteed.

Another point of contention: suspending medication that slows down the puberty process for transgender minors.

Now Humza Yousaf has canceled the agreement, considering that it had "served its purpose". And she has no regrets.

A motion of censure was due to be tabled in Parliament, at the initiative of the Scottish Conservative Party - but the First Minister jumped the gun and walked out.

The Scottish National Party is once again looking for a new leader and, by extension, a new First Minister for Scotland. John Swinney is the favorite, according to Sky News.

The Scottish National Party is beginning the search for the country’s next first minister after a dramatic day in Scottish politics saw Humza Yousaf quit. Former leader John Swinney is an early favourite for the job.

But there is another strong name: Kate Forbes. The former candidate for the leadership of the party has controversial positions - she is against sexual relations between unmarried couples and has even admitted that she would vote against gay marriage if she had the chance.
