This has become a political bloodbath for Humza Yousaf.

He began the day under pressure to stamp his authority at the looming prospect of the SNP's government partners, the Greens, walking away in a row over ditched climate targets and growing scepticism of the Cass report on gender identity services for children.

The SNP leader and Scotland's first minister wanted to reset the narrative, to show he is in control.

He hauled Green ministers in for an 8am appointment, which I understand was very tense.

They were sacked on the spot.

In a hastily arranged news conference, Mr Yousaf told me I was wrong to suggest he is not really pulling the strings.

Let's remember he had hailed the SNP-Green alliance as "worth its weight in gold" fewer than 48 hours earlier.

Whatever his early morning intentions, it is not unreasonable to suggest it has spectacularly backfired.

Today's rail plan by Labour is a landmark moment.

Unlike many aspects of the party's policy offers to date, it is detailed, comes with a blueprint for what will happen on day one, and Whitehall will understand how to implement it.

It is, after all, winding back the clock.

Even the rail companies themselves say change to the train network is needed - though they inevitably don't like this version of their future - and it is not without controversy.

But the row is a fight Labour want to have.

After months of a pro-business love-in from Rachel Reeves and the Labour leadership, it is the single most concrete measure worrying business so far, according to figures from FTSE 100 firms I talked to this week.

They are watching closely to see whether the tendency to squeeze and bash business, evident under ex-leader Jeremy Corbyn, remains in the party's DNA, even if it is well hidden.

Sir Keir Starmer's plan allows the railway companies to come back into public ownership within five years.

But will it leave the railways better off?

The battle for a town that no one there wants.

Sky News is reporting from Grimsby in the run-up to the general election as one of its Target Towns - a key constituency prized by both Conservatives and Labour - Great Grimsby and Cleethorpes.

But it turns out that Grimsby doesn't really want them.

It hasn't always been a town doused in apathy. In 2016, 70% of people here voted to leave the EU - one of the highest results in the country - and in the 2019 election, the constituency turned Tory for the first time since the Second World War.

But five years on, polling by Sky News found that since then, the number of people saying they "almost never" trust the British government to place the needs of the nation above the interests of their own party has nearly doubled - from 26% to 49%.

It's a stark but bleak view. Voters tonight described both leaders as uninspiring and uninteresting.

When asked what they make of the current prime minister, words like 'weak' and 'performative' were used. Voters couldn't make their minds up about the Labour leader, saying they were unsure about him or his policies.

The lack of a clear dividing line between the two parties could be a problem in the general election, especially as both parties have been trying to show a bit more leg this week ahead of a fully-fledged election campaign.

Labour has shown a hint of more radical policies today, with their announcement on aiming to nationalise railways within five years. But have they waited a bit too long to impress the people of Grimsby?

The Conservatives ratified their Rwanda policy into law today, but voters here weren't hugely enthused by that either, with one member of the audience tonight proclaiming they care much more about housing and the environment. They asked - why is the centre of political debate about Rwanda and a policy we don't really care about?

Apathy might override this election.

Scottish First Minister Humza Yousaf will not resign tomorrow, Sky News understands.

A source close to Mr Yousaf told Sky News's Scotland correspondent Connor Gillies he will not resign tomorrow, despite the speculation.

They said: "He is not resigning and is coming out fighting".

Mr Gillies said it was "unclear though whether a speech on independence will go ahead as planned on Friday."

Mr Yousaf is facing a political crisis after the Scottish Greens said they would vote against him in a motion of no confidence.

The first minister had decided to bring the power-sharing deal between his party the SNP and the Scottish Greens to an end this morning, sparking the dramatic row.

The power-sharing deal between the SNP and Scottish Greens was "a useless deal," former first minister Alex Salmond has said.

Humza Yousaf's future hangs in the balance after the Scottish Greens said they would vote against him in a motion of no confidence.

The dramatic fallout was sparked by the first minister's decision to bring the power-sharing deal to an end this morning.

"The agreement had to go," Mr Salmond told Sky News. "But the way that Humza has done it, he's painted himself into an incredibly tight corner.

"It would be fair to say that his first ministership is hanging by a thread."

Mr Salmond, leader of the Alba Party, said the balance of power hangs with Ash Regan, former SNP leadership candidate and Alba Party MSP.

"The Alba Party will write him [Mr Yousaf] a letter setting out our concerns and priorities for the parliament, and Humza's future will depend on his response to that letter," he said.

"If he wants to remain as first minister, then he better give a response which is convincing not just to Ash Regan, but to the Scottish people."

Another Tory leadership contest would be a "catastrophically bad idea," James Cleverly has said, as he warned Conservative MPs thinking of submitting no-confidence letters in Rishi Sunak not to "jump out of an aeroplane" without a parachute.

The prime minister has insisted he intends to call a general election in the second half of the year - but there has been speculation he could call one sooner to thwart a possible Tory leadership battle.

Asked for his message to wavering colleagues, Mr Cleverly told reporters: "If you're going to jump out of an aeroplane, please make sure you've got a parachute before you leave the aeroplane. And don't say 'no, we'll work that out on the way down'.

"I think those people who think that another leadership campaign, as truncated as it might be between now and the election, is anything other than a catastrophically bad idea - I don't get it."

Mr Cleverly said Mr Sunak inherited a "really difficult situation" because of COVID and the Ukraine war.

He conceded the "disruption" at the end of 2022, when Liz Truss was prime minister for 49 days, was "a disruption of our own making".

By Nick Martin, people and politics correspondent 

June gives me a wry smile when I ask her if she trusts politicians. But it soon fades.

"They promise you the Earth, and you don't see anything. And it's soul destroying," she says.

I meet her and husband Joe as they tuck into fish and chips in the town's oldest chippy, the Peabung, which has served this town since 1883.

June tells me she really wants to trust politicians but they "just mess it up every time". I ask Joe if he thinks politicians care about him? "Well hopefully they do. I'm not sure really."

He stops to think for a moment. "I don't really trust politicians," he says.

The findings of a Sky News/YouGov poll are stark and echo how voters like June and Joe feel. The findings suggest voters no longer believe what politicians say.

In some places, there appears to be a deep loss of faith in British politics.

Shannon Donnelly has nearly 200,000 followers on TikTok and has used the platform to develop her Grimsby-based business selling personal safety equipment, such as panic alarms. I ask her if she trusts politicians.

"No - I think things like Brexit has massively changed people's opinion. I won't forget when they said all that money would go to the NHS.

"Now we seem to be in a worse position, but they still expect us to trust them. It's crazy."

The polling was really stark - a collapse in trust in politicians and any faith that they're in it for the right reasons.

In Grimsby, we got an audience together of around 20 to 25 people who are engaged, they care about politics, but they just didn't feel as though they've got anyone to vote for, there's no one that is exciting them at the next election.

So we got them to put their points to the two main candidates for the seat, the Conservative MP Lia Nici and the former Labour MP who wants it back this time around, Melanie Onn. 

I think what I found was that people are desperate for a reason to vote for someone.

So whether that is improving the town centre, whether that is doing action on immigration or the economy, they want to vote but they're just not that convinced by the main parties right now.

The person who stood out for me the most tonight was a girl called Sarah, she's 26, she lives with her mum and dad, and she admitted that if she had the chance, she'd leave Grimsby.

She was really echoing that point that the further you get away from London, the more distrustful you are of politicians.

Grimsby is certainly somewhere that we are going to be returning to in the months ahead of the all-important general election.

With a general election looming, what counts as gains and losses for the main parties in next week's locals?
