And as snapchat and twitter announce big changes to try and attract more users and valuable advertising revenue we are asking are you persuaded . Which social media platform can you live without . Be part of the conversation just use the hashtag bbc the briefing. We start with President Trump, whos given a fresh warning about north Koreas Nuclear threat. Addressing the south korean parliament, he said pyongyang would be making a fatal miscalculation if it took americas past restraint as weakness. He had this message for the north Korean Leader, kimjung un. We call on every nation, including china and russia to fully implement Un Security Council resolutions, downgraded diplomatic relations with the regime and server all ties of trade and technology. It is our responsibility and our duty to confront this danger together because the longer we wait, the greater the danger grows and the fewer the options become. In a moment, well speak to Steve Mcdonnell in beijing where President Trump is heading next. Bur first to our correspondent, mark lowen in seoul. It was a lengthy speech that looked at the stark contrast between the north and south korea. How was it received . I think there will be as sense of relief that the bombastic rhetoric we have heard in recent weeks was largely absent. This was a warning but not a rush to war. He talks about north korea being twisted regime, a dictatorship, a prison state and hard on what daily life was like in north korea, and then compare that to the liberal south korea. He warned north korea not to underestimate the us and try the us. He called on china and russia to up their pressure and sanctions but it was not the rocket man fire sanctions but it was not the rocket manfire and sanctions but it was not the rocket man fire and fury which was a red flag to a bull in recent months to kimjong un . He said he flag to a bull in recent months to kim jong un . He said he would offer a path to a Better Future if you change course and de newk to rise but the problem is that will fall on deaf ea rs but the problem is that will fall on deaf ears because as far as kim jong un depends on being a fully Armed Nuclear state. North korea shows no sign of varying from that path. He is now headed to china. China was mentioned in his speech in south korea, where he talks about the fact that china needs to take steps to help in this situation with north korea. Tell us more about his time in china. I am standing at the back of the forbidden city and us President Donald Trump will arrive in in a couple of tight hours arrived in beijing in a couple of hours. He will discuss these with positioningjinping. They hours. He will discuss these with positioning jinping. They will have a tea ceremony and then a bit of a chitchat. You wonder if they will be speaking about what he mentioned today about what is said regarding north korea. The Chinese Government would say, they are already putting sanctions on north korea but he went further and called on all nations to cut ties with north korea. Britain has a Diplomatic Mission in north korea, is he saying all embassies should be shut down . These will be the debates on what the appropriate way of putting pressure on north korea is. He rhetorically questioned why china would want to support a regime like this and at other times donald trump is said xijinping is doing a greatjob so mixed messages that from the us president and we will have to see what the coming days bring in terms of any sort of a breakthrough because it is hard to see what the way forward is given north korea has shown no indication whatsoever that it is prepared to be anything other than a nuclear state. Thank you to both of you. Both keeping us up to date with Donald Trumps visit in asia. More analysis later in the bulletin. The latest revelations from the Paradise Papers this cache of leaked documents about tax havens show that Prince Charles private estate the duchy of cornwall secretly invested in an offshore company in which a close friend was a director. Thats perfectly legal but hes been accused of a conflict of interest because he went on to campaign for International Rule changes that would have benefited the firm. The princes spokesman insists hes never chosen to speak out on a topic simply because of an investment decision. The Paradise Papers were shared with the International Consortium of investigativejournalists, including the bbcs panorama programme. Andrew verity has this report. Prince charles has campaigned on the environment for decades and especially for the rainforest. He is due to arrive in india after flying for malaysia.

The firm managed sustainable rainforest. The company wanted to trading carbon credit but they were not included so it needed the rules changed. In february 2007, duchy of cornwall bought 50 shares in the company, worth documents were sent to the princes office and soon he was making speeches campaigning the changes to International Agreement on carbon credits. Injune, 2000 acre, duchy of cornwall sold its shares with a profit of more than 200,000. I think it is a serious conflict. There is a conflict of interest between his investments in the duchy of cornwall and what hes trying to achieve publicly and i think it is unfortunate that somebody his importance, his influence, becomes involved in such a serious conflict. There is no suggestion that any of this is illegal, or tax was avoided, and it id impossible to know why the Share Price Rose after Prince Charless estate secretly invested in his friends company. But, for the second time in a week, the Paradise Papers raise serious questions about how royal cash is being managed. Richard bilton, bbc news.

Thereve been two significant victories for the democrats in the united states, in the first state wide elections since donald trump came to power a year ago. Lets get an update from our north america correspondent, peter bowes. Peter, talk us through the winners . This does seem to have been a referendum on donald trump, one year since he was elected president. It was really in the virginia, the key race that people were watching closely. This is a Democratic State that the republicans felt they had a chance of taking the governorship of. It was not to be, the winner was in was in fact the democratic candidate. Certainly as far as the republican was concerned, he fought a campaign, a very competent campaign, certainly along the lines of donald trump in policy, crime, and immigration policies especially. Combative campaign. At a significant, he did not campaign in person with donald trump. The president did tweeting his support, but he seemed to distance himself from the personality of donald trump. And in fact after he lost this election tonight the president has said, ed gillespie worked hard, but did not embrace me or what i stand for. So there is the president is distancing himself from the canada to loss. The democrat who won, ralph norman, said virginians have sent a message that they want to end the politics which have torn the country apart. I think this kind of message resonates around the country with other democrats who will be rejoicing that they can actually win an election with donald trump as president. But will be the message they will take home to their constituencies, looking ahead to the election next year, the very significant midterms. Peter, thank you.

More bad news for englands cricketers as they embark on the ashes series, already without their star ben stokes, they have now lost steve finn, the man called up to replace him. The aussies are, in my opinion, they bring it. Having somebody like ben stokes, who is very strong in himself about how he feels, the competency brings, he would have been quite crucial down under.

We have had some spectacular pictures of the northern lights, the aurora borealis. Here is one from the outer hebrides, another from argyll and bute. This phenomenon as a result of the charged particles racing from the sun in the direction of the earth and colliding with our upper atmosphere. Enough of the science, onto the weather forecast. We have got some cloud and is all across east anglia and the south east. This is where the weather front will be towards the end of the night. Otherwise it is clear, there will be a frost around as well, first thing on monday morning. Mostly outside of town. In the countryside temperatures could get down to minus four degrees in the north of england and scotland. For many of us, it is and scotland. For many of us, it is a beautiful, crisp, sunny start. Not in the south east at this stage. Eight oclock, still cloudy in norwich, milton keynes, london and brighton. For bristol and areas further south west like exit, certainly most of wales, it is a fine start to the day. Exit. Exeter. A chilly start in Northern Ireland and scotland. Rain approaching the Western Isles, and late in the morning it will turn wet and windy again across stornaway, and windy again across stornaway, and most of the Western Isles by the time we get to the afternoon.
