The ice for the World Championship next week in michigan. Remember, you can get in touch at bbc 05. Talks to bring about a Global Nuclear arms ban are under way at the United Nations in new york, but most of the worlds Nuclear Powers are refusing to take part. The Us Ambassador to the un explained why the United States wont be signing this treaty. Is there anyone that believes that north korea would agree to a ban on Nuclear Weapons . So what you would see is the General Assembly would go through, in good faith, trying to do something, but north korea would be the one cheering, and all of us and the one cheering, and all of us and the people that we represent would be the ones at risk. And so weve a lwa ys be the ones at risk. And so weve always said that the United States thinks its important to defend the citizens of our country, butjust as important to defend our friends, citizens of our country, butjust as important to defend ourfriends, our allies and the rest of the countries that want peace in the world. Nada tawfik is in new york and joins us now. I guess the fact that the us and others are not backing the treaty puts a damper on things. Absolutely. We heard from japan, speaking in the General Assembly hall, they are the only country that suffered an atomic attack, and they put the point on this saying, if we have a nuclear ban treaty, but we have none of the Nuclear Powers signed up to it, and if this doesnt stop the development of even a single Nuclear Weapons, what is the point of all of this . We heard from other nations who support and agree with senator haley, and they think an International Framework is in place, and they think there needs to be step by step gradual approach to Nuclear Weapons, because they are concerned about national security. Those supporters of this would say that it is the only Weapon Of Mass Destruction that doesnt have an International Ban on it, and that should be the first step. What i dont understand here is, it was entirely pricked a ball that the us wouldnt sign up to this treaty, so why have the debate in the first place . They are hoping to get a treaty out of this and there is an argument that it of this and there is an argument thatitis of this and there is an argument that it is really a treaty without any teeth if it doesnt have the Nuclear Powers in it. But campaigners are hoping this will at least send a message. It will show that International Norms are against Nuclear Weapons and the proliferation of them, and they think it will force many nations the same way, the cluster ban or the Landmine Conventions have forced other states to change their behaviour and the way they operate. That is the main gimmick you hear from campaigners and supporters of this treaty. Their ultimate goal and ideal is for, late in the process, for the states to sign up to the treaty once they get it ratified. From speaking to the us and britain, the uk, and others, it doesnt seem like they would be interested in that. They see the npt as the goal of the nuclear free world. Nada tawfik, thank you. On wednesday, the british Prime Minister theresa may will trigger article 50. That starts the clock on two years of negotiations for the uk to leave the eu. But scotlands First Minister has a deadline of her own. Nicola sturgeon wants a second independence referendum for the people of scotland before brexit. Theresa may says its not the right time. The two leaders met today in glasgow. And we wondered, has the formerly warm relationship gone cold . Heres Scotland Editor sarah smith. Theresa may knows this could be awkward. Shes here to talk about her article 50 letter. Shes here to press her demand for a referendum on independence. So no handshakes, no press c0 nfe re nce , independence. So no handshakes, no press conference, just a couple of souvenir photographs that neither woman looks like theyre enjoying. By stark contrast, their first meeting, eight months ago, then it was called a good working relationship, now, Nicola Sturgeon says the pm has not listened to her on brexit, theresa may says that she will reject any request for a vote on Scottish Independence. My position is not going to change, now is not the time to be talking about a second independence referendum, because it would not be fair on the scottish people to make them make that decision when the facts are not clear and also because now is the time when we need to pull together to make sure we get the best possible deal for the uk, including the people of scotland. Im told the meeting inside this hotel was businesslike, cordial, and probably the longest meeting yet between them, the Scottish Government were expecting an offer of more powers for the Scottish Parliament after brexit, but they say they got no detail on that. When Nicola Sturgeon told the Prime Minister how she plans to make a formal request for a scottish referendum, the Prime Minister said simply, you know my position on that. The First Minister says mrs may agreed, the shape of the brexit deal should be clear in 18 to 2a months time, which is when the Scottish Government want to hold the referendum. We both agree, now is not the time to ask people to make the choice, but since we both appear to be in agreement as to when the terms of brexit will become clear on the timetable, that would underline my view that that is the right time. Ina in a speech to staff in east kilbride, she says she wants to build a more United Nations. But it is Scottish Independence on the agenda at the Holyrood Parliament tomorrow, and they will almost certainly vote to call for a second referendum. Lets bring you 0s sport now. Usa hockey, thats the Us Association for ice hockey, is holding an emergency meeting. Thats because their womens team is threatening to boycott the World Championships, heres the captain explaining why. She says usa hockey has been desperately searching for replacements, in case it needs them. Look at this, for example there has been support from sponsors and politicians, and we will see from the Mens National team, alan walsh, let me show you his tweet somebody who knows a lot about this, a lot more than me, aj perez, Sports Writer for usa today, whos been following this story. How much support would you say this boycott has . It is pretty much massive support. You mentioned the senators that came out in support, all over social media, the trending hashtag, and so much support, it has been impossible for them to field a team of replacement players. This is a big issue because the championships are being held in the United States, and the american womens team might not play. Exactly. Usa hockey would have to pay a fine if they dont play. It would look bad in front of all the International Teams in michigan. Not having a host team, it has been going on for 4. 5 hours. There has been no progress and time is ticking down. I know that technically, the men dont earn that much more than the women, but actually the male players have a lot more cash, dont they. Yeah, 98 nhl players have played in the olympics. If you are 18 usa player, you make millions in the nhl, there is a leak here that has been around for two yea rs here that has been around for two years for the women, and it has a top pay of 20,000 or 30,000. It is not really apples and apples. women dont get the living wage that they are asking for, and the championship is in a few days, what does american hockey do . Its been tough. Theyve been trying since last thursday to fill the team with players they have gotten from the under 18 s and under 16 s. They have gone down to high school and reached out of players that have been out of the game for a few yea rs. Been out of the game for a few years. They are paying women around the nation, and so far have come up pretty far short of filling an entire team. There is so much support for the boycotting women, they may not have a team and may have to pay the fine. Thanks for bringing us up to date. This is gerard nus. He was a member of ghanas football Coaching Team for the african cup of nations. That ended in february, but mr nus hasnt left ghana yet.

Thats up by more than 5 since the last election. The sdp, led by former eu president martin schulz, polled 29. 6 . Heres a somewhat relieved Angela Merkel. Translation obviously, the citizens have seen that this coalition is a coalition that governs well. We have a lot of hard work to do. It is going to be a difficult campaign, but we have all the chances. I have a lwa ys but we have all the chances. I have always said, it is in the hands of the cdu.
