On this week's show, the future of Greenland, Trump's tariff threats and the defection of former shadow justice secretary Robert Jenrick dominated the conversation.

Culture Secretary Lisa Nandy laid out the government's "non-negotiable" stance on Greenland, and said Starmer was yet to speak to the US president - we've recapped what she said.

Reform UK’s Richard Tice called Trump's tariff threats "completely wrong". On Jenrick, Tice said he would be a "great asset" to Reform UK - here's what else we heard.

And, US Speaker Mike Johnson was quizzed about Greenland before Trump's latest announcement - he said diplomatic channels are the way to go in Greenland.

That's all from us this week, we'll be back next Sunday when Liberal Democrat leader Ed Davey is expected to take the hot seat on Sunday with Laura Kuenssberg.

Reform UK's Richard Tice joined Kuenssberg in the studio this morning, after a last minute switch meant Nigel Farage was absent.

Tice's appearance came days after Robert Jenrick's dramatic defection from the Conservative shadow cabinet to Reform UK.

Tice called the former minister a "great new asset to Reform". On whether Jenrick could be made shadow chancellor, Tice said Farage would make a decision about roles at the appropriate time.

Meanwhile, Tice said Donald Trump's latest tariff threats over Greenland were "completely wrong", adding that the government should negotiate with him "privately".

He called Nato a "strong, very successful defensive alliance", adding that everyone is committed to spending more on defence.

A significant challenge to Labour's approach of keeping Trump closepublished at 10:15 GMT

Ever since Keir Starmer came to power, proximity to Donald Trump has been the central tenet of his foreign policy.

That is coming under strain this morning more than at any other point.

The White House has in effect launched an economic war against its closest allies.

Downing Street officials will be working to try and schedule a call between the prime minister and president.

The last time Starmer wanted a call with President Trump - in the wake of the US strikes on Venezuela - it took several days to actually happen.

Nevertheless the government will hope they can talk Trump down from his tariffs threat.

Whether they can succeed will be a significant challenge to Labour's approach of hugging Trump close.

Culture Secretary Lisa Nandy was grilled on Greenland, following Donald Trump's surprise tariff threat against eight European allies.

Here's what she said:

• Nandy said Trump's response was wrong, deeply unhelpful and counterproductive
• She said the future of Greenland is a matter for its people and the people of the kingdom of Denmark, stating: "That is non-negotiable"
• Prime Minister Keir Starmer has not spoken to Trump, Nandy said, but the UK has a "good dialogue" and a "strong working relationship" with the US
• On last week's other major headline, Nandy branded Reform as a "vehicle for failed Tories" - following Robert Jenrick's defection
• When asked if the government is watering down the Hillsborough Law, after a temporary delay to the next stage of a new law being designed to stop cover-ups, Nandy says she believes it can be resolved: "We will find a way to get this right"

Sunday with Laura Kuenssberg has just come to an end.

In our next few posts we'll bring you a reminder of what we heard, and some analysis from our political correspondent - stay with us.

Following a US operation in Venezuela earlier this month, Kuenssberg asks Johnson whether the US would rule out striking other countries.

"We didn't strike the country of Venezuela," Johnson says, saying the operation was targeted specifically at its former president Nicolás Maduro.

"We're not at war with Venezuela... We removed the leader because he was an indicted criminal in US federal court," he adds.

Asked if he can rule out taking similar actions against other countries, Johnson says if the US legal system indicts someone following proper legal processes the Department of Justice can request the military to assist with apprehending that person.

He reiterates that such an action was not an invasion but bringing a "criminal" to "justice". He adds he doesn't "foresee another scenario like that".

Trump has previously said the only limits on his power are his "own morality", Kuenssberg says. She asks Johnson if the US has king in Donald Trump.

"No, we don't have a king, we have a strong commander in chief," Johnson says.

Asked about whether the US is willing to take military action in Iran, Johnson says "we certainly hope that it doesn't come to that".

The questions move on to whether Johnson is comfortable with Trump's use of executive orders rather than consulting with Congress, Johnson replies: "He does consult with Congress", adding that he and Trump speak "daily".

We're now hearing from US House Speaker Mike Johnson, who spoke to Kuenssberg before Donald Trump announced tariffs on countries supporting Greenland yesterday.

He accepts that Greenland is "not our land" but says it has "strategic importance to us".

"I don't foresee military intervention", he says, adding that "diplomatic channels" are "the way to go".

Should we not pay attention to the president's threat to use military action, Kuenssberg asks.

"No, we should pay attention to his words," he responds, saying some allies now have "people there now".

"Maybe that was the point," he says, "I don't know, the president is playing chess as we say."

Tice is asked if he trusts new Reform recruit Robert Jenrick.

He says that Jenrick is a "great new asset to Reform" and he believes in the principles and values "we believe in".

Tice adds that he brings ministerial experience and there has been a great reaction to him joining Reform.

He is asked if he would be happy if Jenrick was made shadow chancellor. Tice says Reform has a "great range of talent" and Nigel Farage will make a decision about roles at the appropriate time.

• As a reminder, on Thursday Jenrick was sacked by Kemi Badenoch and welcomed to Reform UK - we have more on that here

Tice says that the strength of Nato is the reason why "we're all united that Trump's taking completely the wrong approach," adding that the US president will be hearing from many people in the Davos summit next week.

"Nato is a strong, very successful, defensive alliance, since it was created it's been remarkable," he says, adding that everybody is committed to spending more on defence - which strengthens Nato.

Reform UK's Richard Tice says Trump is "completely wrong" on the tariff threat over Greenland.

Kuenssberg asks him what the government should do. "Publicly, you say [to Trump]: you got it wrong; privately you negotiate," he says.

Tice says negotiations shouldn't happen "in front of the world's press".

But the president needs to know "behind the scenes" that this is the wrong way to go about it, he says.

Asked about previous comments from Reform UK's leader Nigel Farage that Trump would make the world a safer place, Tice says: "It's a work in progress", referencing developments in the Middle East and Ukraine.

Culture Secretary Lisa Nandy is asked about a potential social media ban, as is the case in Australia.

Nandy says the UK is not doing enough as a country to keep young people safe.

She says there are already laws in place to protect young people on the internet but they need to be better enforced.

"Not enough enforcement action is taking place," she adds.

The culture secretary is now asked whether the government is watering down the Hillsborough law.

The next stage of a new law being designed to stop cover-ups has been temporarily delayed after MPs raised concerns about whether it would apply fully to the security services.

"The security services won't be exempt", Nandy says, but adds that the government needs to make sure the law can be applied "without fear or favour".

She says they need to avoid a situation like Manchester Arena, where the security services were able to "withhold information".

"We will find a way to get this right... In the end, we want the same thing," she says, adding she thinks it can be resolved.

The prime minister will meet the families of victims of the Manchester Arena attack and Hillsborough disaster on Wednesday.

• Hillsborough Law - what is it and how did we get here?

Nandy defends Streeting's record on waiting times falling and record investment in the NHS when asked if she thinks he should be sacked.

She says Streeting has "strong views" and she has been a recipient of his views.

Nandy says she wants to be part of a cabinet where people can have their own opinions and "work together in collective interest of country".

"Nothing will distract us from changing this country and putting it back in service of working people," she adds.

Nandy is now pressed about Reform UK and how Labour has been trailing Nigel Farage's party in the polls for a year.

She says Labour is working hard to turn the country round but there is "no magic solution" and there is more that can be done in every bit of the economy.

She says this week has been a turning point for Reform and that welcoming Robert Jenrick shows Reform is a "vehicle for failed Tories from the previous administration".

The culture secretary says the one thing the UK won't do is compromise on their position, "which is that the future of Greenland is a matter for the people of Greenland and the people of the kingdom of Denmark".

"That is non-negotiable, that is the starting point for the conversation, what happens next is a result of the conversations that we'll be able to have".

Pressed on whether the UK would ever allow Trump to take Greenland, Nandy says the government would never allow any changes to be made to the future of Greenland without the consent of the people of Greenland and Denmark.

What often happens following tariff threats is a "negotiation", Nandy says.

Asked by Kuenssberg whether Trump will "chicken out", Nandy says she doesn't think he will, but that an "adult debate" is required.

She says the UK has a "good dialogue" and a "strong working relationship" with the US. While there are some clear differences of opinion, this is "something we're able to talk about and resolve in our collective interest", she says.

Nandy adds that the conversation about tariffs, which Trump has threatened to impose on eight European countries including the UK, is "wrong, deeply unhelpful and counterproductive".

"The prime minister has not shied away," Nandy adds.

Lisa Nandy adds Trump is very concerned about the threat Russia poses in the arctic.

She says the foreign secretary has just got back form the north of Norway where the UK has been making a statement about the importance of the region and it will be doubling the number of the marines in the region over the next three years.

The UK's position on Greenland is non-negotiable, Culture Secretary Lisa Nandy tells the BBC.

Nandy says the prime minister has not spoken to the US president directly since the latest developments on Greenland, but she adds that Keir Starmer has made his views clear.

Asked whether she believes Donald Trump will back down from his threats in relation to Greenland and tariffs, Nandy does not answer directly.

She says, though, that the UK has to have a "sensible dialogue" with the US.

"It's in our interest to talk," Nandy says.

She adds that the future of Greenland is for its people and the Kingdom of Denmark to decide.
