hadrian's wall. tax cuts. there was a lot of hope with nafta. donald trump wants to make these cuts but they have to get through. this is his very childlike desire. it sounds great, getting these tax cuts and having a multiplier effect across the economy. it would be fantastic. but it is not going to happen, of course. because even the sensible pa rt course. because even the sensible part of the republican party is saying that is going to create a huge deficit. the issue with donald trump as we come up to 100 days, is, what was he saying, i am here to clear the swamp the pity is up to his eyeballs in alligators. he discovered, we are discovering, the problem is not donald trump, it is the republican party. the democrats

are saying let them make another mistake. is it a big problem? is just the way democracy in america works? you end up with different points? the way that democracy in america works. —— works. the worst form of government except for anything else, democracy. donald trump has come in saying he will deliver and he has been stopped every time. the markets believe he still can do it, but at some stage that will lend. president trump. xi jinping. he said he wants to reduce the deficit with china. america, $300 billion. americans buy more from china than china from america. here is a way to reduce that deficit, right? the story is that

alibaba will deficit, right? the story is that aliba ba will host deficit, right? the story is that alibaba will host a conference to teach companies how to sell their goods. that is good. we are opening up goods. that is good. we are opening up the chinese on line market, which is the most important way of selling things in china. on line selling is afar things in china. on line selling is a far bigger part of the economy thanit a far bigger part of the economy than it even is in europe or the us. it is vitally important. but on the other side of the equation is that there are wealthy people in the cities in china where their incomes are much, much lower per capita. america has high value finished goods. the question is, does america... you can open up the market but if you don't have the right things to sell it is a little bit like windowdressing. but good windowdressing. the last story about webcams in chinese classrooms. it does not seem like a good idea. imagine knowing that parents could get annoyed. notjust parents. had

in many respects. but before we get there, yesterday we had some really big thunderstorms around, this one brought some hail to west hamstead. thanks to our weather watcher dg perry for sending us that picture in. you can see the extent of the showers as they've worked in. the showers have tended to die away overnight, just one or two left over, working towards parts of central and southern england. but by and large today we're looking at quite a cloudy weather picture for many of us, and there will be some showers knocking around as well. ok, let's take a look at how the weather starts off in the morning. quite a lot of cloud around, some showers really from the word go across north—western areas. towards southern parts of england and wales, this is where the clearest weather will be. certainly a cold start to the day. we're looking at some patches of frost around. probably the lowest temperature about —3 or so. so a cold and locally frosty start to the morning but it should be reasonably bright. the brightness won't last, though, because quite quickly we're going to see an area of cloud come down from the north and that will tend to trap all cold air at the surface. so it's one of those days i think

when temperatures will be very slow to rise. across more northern areas, northern england, northern ireland, scotland, quite a cloudy start to the day, occasional brighter spells, but already a few showers from the word go. quite breezy for northern scotland as well and through the rest of the day, the showers that are really associated with these weak weather fronts will continue to slide southwards, it will tend to turn cloudier and cloudier as the day goes by and eventually we'll start to see those showers working in across east anglia and south—east england as well. while the weather brightens up for scotland, northern ireland and late in the day the far north of england. temperatures generally about 11 degrees for many of us. now, looking at the weather picture through the night time and those showers will continue to push southwards. so quite a bit of cloud initially but then the showers fade away and the skies clear during the second half of the night. again that will allow things to get quite chilly. there'll be some pockets of frost developing by the time we get to friday morning across parts of scotland and the far north of england in the countryside. here's friday's weather picture and generally quite a quiet weather day.

again we're looking at a few showers, most of these will be across eastern parts of scotland, eastern england, but for many of us it's a dry and a bright kind of day, amounts of cloud coming and going through the day and temperatures will be rising a little bit. highs between 11 and 1a celsius. feeling a little bit more pleasant. and that trend i think continues on into the first part of the weekend. saturday by and large a dry day with some sunny spells, a few isolated showers possible across western areas, but for most of us a quiet weather picture. those temperatures continuing to rise, 12—15 degrees, not bad for the start of the weekend. that's your weather. hello, this is breakfast, with charlie stayt and sally nugent. deepening tensions in north korea: the us calls for tougher sanctions until it dismantles its nuclear programme. america is piling on the pressure as all 100 us senators attend a special briefing at the white house. we'll ask the foreign secretary borisjohnson what the uk can do about north korea, just after 7am. good morning, it's thursday
