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? 

Sky's election analyst Michael Thrasher tells us what to look out for:

Thank you for watching the special edition of our weeknight politics show Politics Hub With Sophy Ridge.

The Target Towns special saw Sophy discuss trust in politicians with a live audience and speak to Conservative MP for Great Grimsby, Lia Nici and her Labour challenger, Melanie Onn.

That's all for now, stick around on the Politics Hub for the latest political updates.

Watch Politics Hub With Sophy Ridge from Monday to Thursday on Sky channel 501, Virgin channel 602, Freeview channel 233, on the Sky News website and app or on YouTube.

Sophy asks the candidates what their pitch to Grimsby voters would be.

Labour challenger Melanie Onn says: "The reason I got into politics was to give back to my community. I was helped when I was homeless when I was 17 by a charity in this community.

"I understand the challenges that people face and I think people want to know that there is some compassion in their politics.

"I think people are tired of the tit-for-tat. And there is an awful lot in the community that I would like to continue to champion and work alongside people."

Conservative MP Lia Nici says: "The tit-for-tat that you see, PMQs, that isn't really what happens. That's the theatre bit. What your MP does is go out, have a look at the legislation and then fight for your town.

"I love Grimsby, I've lived here all of my life, I grew up here. And I stood never thinking that I would become the MP, but I work hard every day to make sure that I'm listening to what you want and to be able to represent that at the heart of government.

"Grimsby is absolutely the top priority for me and it's a great place to be and it's going to grow and it's going to be even better in the future."

Sophy asks the audience if anyone has changed their mind or been persuaded to vote after the show tonight - but no one puts their hand up.

Conservative MP Lia Nici says there will be a "massive cut" in immigration figures when the next figures are released.

"I've challenged the prime minister, each prime minister," she tells Sophy.

"Last autumn I went to see Rishi Sunak and said 'we want to see 'illegal migration halved', he listened to us, and now when we see the next figures coming through you'll see a massive cut."

She admits the number will not actually be halved, but says she expects it to be around 350,000.

The Reform Party is "not a fully formed political party," Tory MP Lia Nici says, adding she is "not worried about any opposition".

"I'm probably more Reform than most Reform candidates, to be honest," she tells Sophy when asked if she was concerned the party could take Conservative votes.

"I'm constantly called a rebel, but that's because most people in Grimsby think in a similar way to the way I do, so I hold our government to account on that."

She adds: "Reform have got a lot of ideas that people locally do like, but are they a fully formed political party? No they are not."

Patrick, the owner of one of the earliest fish smokers in Grimsby tells Sophy he thinks the town is "often dumbed down".

He adds "particularly by the media, who come with a narrative because they see this place and they want to agree with some sort of narrative."

Instead he says the town is doing well, adding: "All the major fish processing companies are thriving, they're successful, they're where. We have the only protected food name in all of Lincolnshire - that's worth shouting about.

"And we're a bit too keen to dumb ourselves down."

He says there should be half as many MPs and they should be paid three times as much, to "get some good ones".
