Earlier, the prime minister urged Donald Trump to come up with a new plan to stop Iran acquiring a nuclear weapon.

He said the UK would support the existing deal until a "replacement" was found, but said "from the American perspective, it's a flawed deal".

However, the BBC now understands the PM was not suggesting that the deal - known as the Joint Comprehensive Plan of Action or JCPOA - should be scrapped, but that it needs to be made to work in a format that the US would sign up to.

No 10 says Mr Johnson’s remarks this morning are consistent with the government’s backing for the existing nuclear deal, which it has reaffirmed in recent days.

But his language sounded quite different this morning...

The PM said earlier that the government will be bringing forward their social care plan "this year" and "will get it done within this Parliament".

He added "this is a potentially massive change in how we fund social care and we've got to get it right".

The BBC's economics editor Faisal Islam says Mr Johnson's answer is "interesting" - including the PM's plan that people don't have to sell their home to pay for their care.

Our correspondent says: "Plan difficult because of moral/social issues such as 'what is the relationship between families you want to encourage', eg. getting families to look after their elderly."

The BBC Breakfast interview has made its mark on Twitter this morning.

At the moment #BBCBreakfast is the top trend on the social media site in the UK.

Dan Walker is enjoying fourth place - in part because of a joke about replacing the Breakfast presenter with the BBC's Andrew Neil, after the PM avoided an interview with Neil during the election campaign.

Labour is now having its say on the prospect of the government intervening when it comes to the future of troubled airline FlyBe.

In his interview this morning, Boris Johnson would not make a firm commitment about government involvement, or a lack of it, merely saying: "We are working very hard to do what we can."

But shadow chancellor John McDonnell is criticising reports the government may cut air passenger duty on all domestic flights to help the airline recover.

He says: "Bailing out a company through a tax cut across the industry is not the way forward.

"Working with the company and unions, the government should look at targeted assistance to support routes judged on economic, environmental and social grounds."

Reality Check

It is "epically likely" that the UK will secure a comprehensive trade deal with the EU by the end of the year, the PM told BBC Breakfast.

If the UK fails to secure an EU trade agreement at the end of the transition period, many UK goods could become subject to tariffs (taxes) and other trade barriers could go up.

The UK will also need to roll over the existing trade deals that the EU has with other countries (which the UK benefits from).

So how much progress has the government already made? Reality Check has been keeping track.

Earlier, Mr Johnson said there was no reason for the UK to be informed beforehand of the US plans to kill top Iranian military leader Qasem Soleimani.

BBC political correspondent Iain Watson says "with British personnel in the Middle East, there may be a few raised eyebrows to say the least" over these comments.

Meanwhile, on Huawei, our correspondent says Mr Johnson's answer on BBC Breakfast "sounds like gentle pushback on US pressure".

Mr Johnson said "if people oppose one brand or another they must tell people what is the alternative" - although added he won't compromise on security.

During the election, Boris Johnson said the chance of no trade deal being done with the EU by the end of 2020 was "absolutely zero".

In his interview this morning, he said it's "very, very, very likely" a deal will be done.

So, what will the PM say in another few months?

BBC Breakfast

Mr Johnson said the cost of arranging for Big Ben to chime as the UK leaves the EU on 31 January would be about £500,000.

He added that he was "working on plans" to see if it could happen all the same.

Reality Check

Boris Johnson pointed out his government's pledge to recruit 6,000 more GPs.

But GP recruitment has proven challenging in the past.

In 2015, the then health secretary Jeremy Hunt made a pledge to recruit 5,000 more GPs in five years.But five years on, we're more or less where we were in 2015.

Numbers have declined slightly from 29,403 full-time equivalent GPs in September 2015 to 28,315 in September 2019, according to NHS Digital figures.

There have been more GPs recruited but also more retiring early.

Dan Walker covered a lot of ground in that interview. But I think the overall impression was one of extreme caution.

When it came to Iran, there was nothing there suggesting this was a prime minister sticking his neck out. Rather the opposite.

He was obviously happy to accept the apology of the Iranian leadership for the downing of that aircraft.

Maybe that is not a surprise. Britain's contribution has been all about chorusing the case of restraint.

But equally, he was very cautious when it came to whether or not Britain should have been involved, or informed, or at least consulted, before the attack on Iranian General Soleimani.

[The PM said there was no reason for the UK to be notified beforehand as it "was not our operation"]

And when it came to the wider issues, there were lots of promises of great reform, but very little detail at all.

BBC Breakfast

An unexpected topic rounds of the interview. Veganuary.

While the PM says he hopes to lose some weight this year, he adds that he is not taking part in the campaign encouraging people to ditch animal products for the first month of the year.

"I had thought of it but it requires so much concentration," the PM says, adding: "I take my hat off to vegans who can handle it."

"You can't eat cheese, can you? You can't eat cheese if you're a vegan. It's just a crime against..."

Dan Walker helps Mr Johnson out, suggesting: "Cheese lovers?"

And Mr Johnson agrees, confirming: "It's a crime against cheese lovers."

Boris Johnson has just taken part in a 30-minute interview with BBC Breakfast's Dan Walker inside No 10.

If you missed any of it, these are the main points to come out of it:

• The PM said he was "glad" Iran had taken responsibility for the the shooting down of a Ukrainian passenger plane that killed 176 people, but "the most important thing is tensions in the region calm down"
• He doesn't say whether he should have come back early from his holiday after the killing of Iranian General Qasem Soleimani, but says the region is "in a better place now"
• Mr Johnson refuses to give a personal view on the future of Prince Harry and Meghan, but says he is "a massive fan" of the Royal Family
• The PM says it is "enormously, epically likely" there will be a trade deal with the EU by the end of 2020 post-Brexit, but said he accepted "you always have to budget for a complete failure of common sense"
• He says the NHS is his "number one" priority, but repeats a number of claims that BBC Reality Check has raised questions about - such as the amount the government is putting into the NHS and how many hospitals they plan to build
• Mr Johnson pledges to bring forward a plan for social care this year, with it being implemented by the end of the Parliament
• The PM says he wants to improve regional connectivity, but he will not reveal if stepping in to save beleaguered airline FlyBe will be part of that
• He says the chance of the US extraditing the American accused of killing 19-year-old Harry Dunn is "very low"

• On the plane crash: Mr Johnson said he was glad Iran had identified the downing of the Ukrainian International Airlines flight, which killed 176 people, as an "appalling mistake". He added that it was important the bodies are now repatriated. "Iran made a terrible mistake, it's good they have apologised," he said. He said "the most important thing now is that tensions in the region calm down". Pressed on whether Iran should face consequences, Mr Johnson said: "They're clearly guilty of an appalling error, I don't think we are currently envisaging any further escalation of the tensions."
• On the killing of Soleimani: Mr Johnson admitted he was on holiday when the news broke about the US killing of the Iranian general, but says he "worked very hard to ensure there was a European response". The PM said there was no reason for the UK to be notified beforehand as it "was not our operation".
• On the nuclear deal: "Let's work together to replace the JCPOA and get the Trump deal instead" - they were Mr Johnson's words when asked about the Iran nuclear deal (the JCPOA), which has been abandoned by the US. Mr Johnson said his message to the US is "somehow or other, we've got to stop the Iranians acquiring a nuclear weapon". If we get rid of the current deal, he added, we need a replacement
• On Nazanin Zaghari-Ratcliffe: Mr Johnson said "it's hard to say" whether the death of Qasem Soleimani has made the case of the jailed British-Iranian woman "more or less difficult". The husband of Mrs Zaghari-Ratcliffe said he is worried abut the consequences of the latest developments in tensions for his wife's case.
• On Iran generally: Mr Johnson said Iran "is an amazing country... they should be orientated towards free markets, towards our way of doing things". He repeatedly called for a de-escalation of tensions.

Reality Check

Boris Johnson has again said that the Conservatives are recruiting 20,000 police officers.

Since 2010, police officer numbers have decreased by 20,500.

The recruitment has already started, but it isn't clear whether new officers will all work for territorial police forces, or other agencies like the National Crime Agency.

The PM is asked where he stands on the death of 19-year-old motorcyclist Harry Dunn, who died after being hit by a car outside RAF Croughton.

Anne Sacoolas, an American who was allegedly driving the car, is now the subject of a UK extradition order - a move the US has branded "highly inappropriate".

While Mr Johnson says the extradition appeal is "right", he adds: "I think the chances of America actually responding by sending Anne Sacoolas to this country are very low.

"That's not what they do. But we will continue to make every effort that we can."

Reality Check

Boris Johnson repeats his election pledge to build "40 new hospitals".

We looked into this in December: 34 projects are getting "seed funding" of £100m and six are getting £2.7bn over 5 years (some of these are redevelopment projects on existing sites).

On the topic of infrastructure, Dan Walker asks about the future of FlyBe - the airline in trouble of closing.

Boris Johnson says: "It is not for the government to step in and save companies that simply run into trouble.

"But be in do doubt, we see the importance of FlyBe delivering connectivity across the whole United Kingdom."

But does that mean the government will help? Ministers are meeting the company later after all...

The PM says: "I can't go into commercially confidential discussions. But we are working very hard to do what we can."

Returning to his pitch from the election, Mr Johnson adds: "We don't have good enough infrastructure in many parts of the country and people don't feel they have the opportunity to get to the high-skilled, high-paid jobs.

"We want to ensure regional connectivity... it is part of the agenda."

BBC Breakfast

Mr Johnson is also being pushed on the issue of social care.

He has previously said he has a plan to help people to get the care they need, but has not yet made the plans public.

Pushed for a date on when he will make changes, the PM says "certainly within this Parliament".

"We'll bring forward the plan this year, but we will get it done within this Parliament. It's a big, big thing," he adds.

"[The issue] has been shirked by governments for about 30 years... so we're going to get on and deal with this, so that people get the care they deserve in their old age but don't have to sell their homes."

BBC Breakfast

Dan Walker asks what the prime minister will do to repay the voters in the north of England within the next year.

Boris Johnson doesn't make any firm commitments for the next 12 months.

However, he does say: "London has been doing fantastically well for some time, and our great metropolitan centres [are too].

"But [in] too many towns, people growing up feel they don't have opportunity."

The PM says: "Through fantastic infrastructure, better roads, better rail, better broadband, but also through better education, [we can] give people better chances to exploit their talent."

He promises the government will "work flat out" to achieve it.
