PLAID Cymru Westminster leader Liz Saville Roberts has welcomed Jeremy Corbyn's call to work together in a time-limited caretaker government, but said Labour has to "let go" and back a second referendum.

Speaking on BBC Radio 4's Today programme, Saville Roberts said: "I welcome the fact that at last Jeremy Corbyn is reaching out, that he is making a serious attempt in recognition that we have to work together to stop a No Deal.

"No Deal would be such a disaster. It isn't a matter of party interest, it isn't a matter of personality interest, we now have to put what is best for our communities and our countries in the United Kingdom first.

"In that respect, I would call on Labour now, seriously, let go. Stop clinging to what you said in the past. We need to work together seriously. In that respect we need to put a referendum first."

Anna Soubry, leader of the Independent Group for Change (formerly Change UK) said she could not support a government led by Jeremy Corbyn.

Soubry told the Today programme: "I would not support a government of national unity that is led by Jeremy Corbyn for all manner of reasons.

"One, because I don't think it's genuine, secondly because it is not going to deliver a people's vote which is the only way through the chaos, and, of course, he doesn't command support or respect in his own political party, never mind across the Parliamentary divide."

Totnes MP Sarah Wollaston, who has joined the LibDems, said she chose to make the switch to help make an "unequivocal case" against No-Deal Brexit.

Speaking on BBC Radio 4's Today programme, Dr Wollaston said: "I think you can work much more effectively in the House of Commons as part of a team and I think the Liberal Democrats is a fantastic team, not only the work they are doing around social justice but, crucially at this point, making the unequivocal case for us to remain at the heart of Europe and tackle no-deal, which would be a disaster."

She added: "The more people that join the Liberal Democrats and are making that unequivocal case I think the better and the most significant feedback I got over the European election was that people wanted to see a single unified force making the case against no-deal."

Dr Wollaston said that, while her constituents in Totnes had voted for her initially as a Conservative candidate, they had wanted a "centrist" MP.

She said: "Many of my constituents have been rather horrified by the way the Conservative Party have shifted to the right. And I was selected originally by a fully open postal primary, the first in the country, so I think that people do have a support across my constituency for that kind of centre-ground approach.

"The point is that we are at a time of national crisis now. If you've got such a great policy idea, why do you have to spend billions on making contingency plans for air freighting in medicines and food? It is not good enough, and people deserve a say on that."

She said LibDem leader Jo Swinson is being "realistic" in not supporting Jeremy Corbyn, and said he "won't find the support of the Commons". She said, instead, that none of the party leaders should lead a temporary government, saying a "trusted figure" like Ken Clarke or Hilary Benn would be better.

She added: "I think it should probably be none of the party leaders that head that temporary arrangement if that's where we get to. I think having a trusted figure that commands cross-party support would be much better for that very temporary arrangement if, indeed, that is one of the ways we go forward."

SNP Westminster leader Ian Blackford said he believes there is a majority in Parliament against a No-Deal Brexit.

Blackford told BBC Radio 4's Today programme: "I think really what is important is we tackle the immediate crisis in front of us, and that is the very real threat we have of leaving the European Union on a no-deal basis at the end of October, and I do believe, I strongly believe that there is a majority in Parliament against No-Deal."

He said he wrote to Corbyn asking for a meeting between all opposition leaders to put a "broad coalition" together to focus on opposing No Deal.

He added: "I believe that when we get back to Parliament in the first week of September that we can bring forward legislation, we can do it through a mechanism called a SO24 application to stop no-deal. And that is what we should be focusing on.

"It's not about, in this immediate case, who is prime minister, it is about stopping that act of economic self-harm that all of us would suffer from."

Blackford added: "There is a demand for an independence referendum in Scotland, that is now being demonstrated.

"The Scottish Government has a mandate for that, and it is only right and proper that whoever is in power in Westminster recognises the sovereignty of the Scottish people.

"The people of Scotland have got to be able to determine their own future, and that will happen."

Shadow business secretary Rebecca Long-Bailey has issued a "plea" to Liberal Democrat leader Jo Swinson to back Jeremy Corbyn's calls for a temporary government to fight a no-deal Brexit.

Speaking on BBC Radio 4's Today programme, Long-Bailey said: "What I would say is issue a plea to Jo Swinson particularly.

"I know that Jo wants to avoid a no-deal situation, as we do, and we think this is the simplest and most democratic way of doing that.

"This isn't an issue about personalities and politics, it's not about implementing Labour policy; it's about avoiding a no-deal situation arising and ensuring that a general election is called so, ultimately, the people can decide which government they want."

Swinson had dismissed Corbyn's letter calling for parties to work together as a "nonsense".

Long-Bailey said: "I think it is sad Jo has made those comments, but I wouldn't close the door completely."

She added: "We have to work together, even if we don't like what each other says a lot of the time, but we have to stop no-deal. It's as simple as that, because we know the damage that could be caused is unfathomable."

Asked when Labour would call a no-confidence vote, Long-Bailey said: "Certainly, we'll back it in early September. Obviously, we won't dictate which particular day that will happen on, but as soon as possible."

She said she "suspected" it would be called "within days", but declined to give a specific day.

She added: "We remain committed to a public vote on the terms of leaving the EU with an option to remain.

"In the situation we're in at the moment, if it looked like we were going into that public vote with just no-deal on the table then, of course, we would campaign to remain.

"If it was a bad deal, again, we would campaign to remain.

"But in terms of what a general election manifesto would say, we are a democratic party and ultimately we will be having discussions over the coming months, you know, in terms of what that final position would be, whether it would involve any renegotiation, whether it would be straight to the public vote.

"But, ultimately, whatever deal is there finally, or a no-deal, that would be put to a public vote."

She said that vote would include an option to remain.

Shadow chancellor John McDonnell tweeted: "Good to hear that Plaid, SNP and Conservative MPs have responded positively to Jeremy Corbyn's Caretaker Government offer by confirming that they are willing to meet. We have to prevent the dangerous No Deal Brexit that Johnson is so recklessly willing to inflict on our country."

Labour Party chairman Ian Lavery tweeted: "Why would anyone be surprised at the @LibDems refusing to meet @jeremycorbyn to avoid a NO DEAL BREXIT?

"All other parties are willing. They were so so so cosy being in bed with the Tories dishing out right wing policies damaging our people & communities."
