and london. this is bbc good morning. it is 8am in singapore, 1am in london and 3:00 in the morning across turkey, where a referendum has granted president erdogan a wide range of new powers, but with the narrowest of majorities, just 51.3% of the vote. it means the role of prime minister will be scrapped, and turkey will become a presidential democracy. but opponents say it won't have the checks and balances of similar systems around the world, and are disputing the results, alleging widespread irregularities. from istanbul, our world affairs editorjohn simpson sent this report. tonight, the victors were out in force, celebrating as though they had won by a big majority,

instead of by a whisker. in fact, here in istanbul, and in turkey's two other largest cities, izmir and ankara, the capital, the no campaign seems actually to have won. the worry is that the result has been too narrow to settle anything for good. the bangs are notjust fireworks. those are guns being fired. the fact is that there is a big underlying level of nervousness and anger here, which really the result of this referendum, being so close, hasn't done anything to calm down. however slight his majority in the referendum, president erdogan has taken the decision to push through his far—reaching constitutional changes, and deal with any consequences. translation: this is not an ordinary day.

these a very serious changes are underway, for turkey's future. then he went out to speak to some of his supporters face—to—face. they chanted, bring back the death penalty, and he seemed favourable to that. his argument all along has been that only a really strong presidency can galvanise turkey into being successful and wealthy, so he is getting rid of the old constitution‘s checks and balances. he is giving himself the power to hire and fire the country's judges, and he has made it possible for himself to stay as president until 2029. the yes campaign might not have won the popular vote in the capital, ankara, but there tonight, it had its celebrations all carefully choreographed in advance. this has indeed been a day on which history was made,

but it is likely to cut turkey off further from its old allies in western europe and america. what we have seen today looks like a major change of course. well, residents in istanbul and across turkey have been marching in protest against the referendum result. these pictures are from the capital ankara where scuffles broke out between people supporting the ruling ak party, and those aligned with the opposition republican people's party. riot police were called in to prevent further clashes. so where to next, for turkey? from ankara, here's our turkey correspondent mark lowen. you have one side of the country tonight that is jubilant, that feels it has clinched victory, and it has given president erdogan — given him sweeping new powers. the other side of the country that is not accepting this result,

claiming massive voting irregularity, saying that 1.5 million votes which should have been declared invalid, because they lack the official stamp of the electoral supreme board, were actually given to the yes side, and that electoral observers were blocked from south—eastern polling stations, in the south—east of the country. they have vowed, the opposition, to challenge this at the high court, at the electoral supreme court. so really, in a sense, in terms of the stability of turkey in the short term, going forward, this is possibly the worst possible result, going forward. and really, when you look at the breakdown of the votes, the more rural, higher side of the country voting in favour of president erdogan, the more cosmopolitan, western—looking cities voting against him. turkey is split down the middle, more polarised than ever, we will get more analysis of us are

later on. also making news today: the iraqi military says that, following fierce fighting with islamic state militants, its forces have pushed deeper into the heart of the city of mosul. after weeks of near—stalemate, the government forces say they managed to advance some 200 metres. gaining ground in the old city has proved particularly difficult. united airlines is changing its policy of giving staff last—minute seats on full flights after a man was dragged screaming from an overbooked plane. the airline said that in future crew members would be allocated seats at least an hour before departure. it comes after passenger dr david dao lost two front teeth and suffered a broken nose when he was forcibly removed from a flight. the italian coastguard said more than 5,000 people had been picked up from un—seaworthy boats off the libyan coast over the previous two days. it's thought that fine weather and calmer seas have led to an increased number of attempted mediterranean crossings by migrant vessels.

the launch is being seen as a provocation, coming shortly before the us vice president mike pence arrived in south korea. 0ur correspondentjohn sudworth is in the north korean capital, where his movements are being monitored and tightly controlled. this flower show, like almost everything else in north korea, is dedicated to its ruling family. this is the stand of national defence industry... and this display is in honour of their abiding obsession, missiles. is it a little strange to have rockets and missiles in a flower show? no, not strange at all. there are reports that there was a missile test this morning... yeah. ..and some suggestions that it failed. have you heard these reports? this is not a failure. we will win, and we will have greater successes in the future. there has so far been no mention of the missile on north korean tv.

but it is true, every launch, failure or not, takes the military one step closer to its goal. the timing of the latest missile test is significant, coming just a few hours before the us vice president, mike pence, arrived in the south korean capital, seoul. it is a message of defiance from here in pyongyang. its quest to become a fully—fledged nuclear power continues. at its big military parade, it put some of its newest missiles on display. the decades of threats and sanctions against north korea have clearly done little to stop it. mr pence's talks will focus on trying to find something that will work. including military options, according to officials. senior officials say military

options are still on the table. our commitment to this historic alliance with the courageous people of south korea has never been stronger. we are working together with our allies and partners and with the chinese leadership to develop a range of options. at pyongyang's zoo today, there was a relaxed, holiday atmosphere. the looming crisis seems far from anyone's mind. north korea appears confident that president trump's threats will turn out to be hollow, and that he will conclude, like others before him, that war carries far too many risks. earlier i asked the bbc‘s steve evans in seoul about the range of options being discussed and that it needs the cooperation of many players.

we are trying to work out what the policy now is, because initially mr trump was saying that it was a big break from the past. and it is now becoming clear — that clip you played earlier of mr mcmaster, his national security adviser, there is a key quote in that. "it is time for us to undertake all actions we can, short of a military option, to try to resolve this peacefully." so they are now ruling out a military option. now, as the trump has been tweeting overnight, the real donald trump, the tweet says, why would i call china a currency manipulator when they're working with us on the north korea problem? we'll see what happens. so the policy is to put more pressure on china, to put more pressure on north korea via beijing, stay back from the military option, though hold that in reserve. now, sceptics will say that that's

pretty well the 0bama policy. you have this fundamental, which is that if you attack north korea, north korea may attack south korea, and that would be a very serious act indeed, probably costing many lives. so you are now getting a sense of the new policy bedding down. mr pence is going to talk to the leaders of south korea in a few hours, and he is going to do two things. he is going to say the alliance is strong, despite what mr trump may have indicated before the election, and what more pressure can be put on north korea. the real key pressure that could be put on north korea doesn't come from here. it comes from beijing. beijing could stop the north korean economy, if it chose not to provide fuel oil. it has been reluctant to do that in the past. will it now change its mind, in return for a trade deal, maybe? that remains to be seen. you are watching newsday on the bbc.

still to come on the programme: in a couple of hours' time, china will release the latest figures on the state of its economy. we will look at what we can expect. pol pot, one of the century's greatest mass murderers is reported to have died of natural causes. he and the khmer rouge movement he led were responsible for the deaths of an estimated 1.7 million cambodians. there have been violent protests in indonesia where playboy has gone on sale for the first time. traditionalist muslim leaders have expressed disgust. the magazine's offices have been attacked and its editorial staff have gone into hiding. it was clear that paula's only contest was with the clock and as for a sporting legacy, paula radcliffe's competitors

we start with the south china morning post. it covers the story which has been dominating events in east asia in recent weeks and months, north korea's military ambitions. it says that the latest missile test was an act of defiance by pyongyang, even though the medium—range missile exploded just moments after taking off. the same story leads on the front page of the japan times, but it takes a slightly different line. it sees the north korean missile launch as a test for the us president, donald trump. and it notes that mr trump was, in its words, uncharacteristically silent on the events. and in singapore, the straits times also looks at the same lead story. it looks at the way it says the us and its allies are considering a united international response. it notes that the us and china have been discussing the north korean missile launch at a senior diplomatic level.

let's return to the referendum result in turkey. from washington, we are joined by stephen flanagan, a senior political scientist from the think tank the rand corporation. he is in washington. given the fact that erdogan had much bigger resources than the no campaign, his message was ubiquitous, are you surprised by actually how close this result was? no, not at all. actually the fact that the vote was so close to suggest that the country remains deeply divided over this move towards the development of a very strong executive presidency, with few checks and balances. the country, if you look at the preliminary results, it was divided

along the lines of the anatolian heartland, where erdogan‘s race resides, he is heavily supported. the three largest cities in the coastal areas and the kurdish regions in the south—east, all of those actually supported the no vote. so does underscore that the country remains very wary of how erdogan, particularly given his record over the last several years, might use these powers that the constitutional amendments would award him, and the dominant party. now, he is being pretty fiery in his rhetoric since this result has come through. he is now talking about the possibility of another referendum on reinstating the death penalty. 0bviously for the eu that would be a com plete 0bviously for the eu that would be a complete aversion to its whole ethos. is this the end of turkey ever joining ethos. is this the end of turkey everjoining the eu, is that over now, with a more western society? well, it depends on, as you said, how he does play from now on there we re how he does play from now on there were some who hope that if the victory was a bit larger, he would

temper his approach and use the next few years to show that, as he was going to accrue these new powers, but they would be used for the purposes that his party and he have portrayed it, to help revive turkey, to get the economy going, and to deal with the terrible security situation. but i think, given the closeness of the vote, a number of us closeness of the vote, a number of us who have watched this closely are concerned that he may double down a bit over the next several months, to ensure that he does continue to keep the pressure on his adversaries, perhaps step up the counterinsurgency campaign, and also perhaps keep up the rhetoric, you know, that has been rather hostile to european and other outside, as he sees it, interference in turkey's domestic affairs. and stephen, he is talking about these changes to the constitution, saying that he needs them for security reasons. of course we had that to nine months ago. is it justified, what he we had that to nine months ago. is itjustified, what he is trying to do? well, the idea that they made

need extraordinary powers to deal with the security situation is one thing. it is more the way this would shift... the shift towards the executive presidential system that is envisioned under this constitutional change would eliminate many of the checks and bala nces eliminate many of the checks and balances that exist currently in turkey, and also in other countries with strong executive presidency is, like the united states and france. the president would have almost full control over the appointment of the government, the budget and the constitutional court. and so it would give him sweeping powers to be bothjudge and jury would give him sweeping powers to be both judge and jury on his own policies. and any successive president, obviously this is not just a question of how president erdogan and the currentjustice and development party might use these powers, but how any future party might use them. so that concern is more about how this might impact human rights, how will this affect in particular, i know that the kurds and a number of other minorities within turkey are quite concerned that that could lead to further

repression against them. fascinating to speak to you, thank you. every three months, almost like clockwork, the world's economic experts can be found gathered around their computer screens waiting to see what china's latest quarterly gdp figures will reveal about the world's second—largest economy. that day has come around again. i asked dan wang, a senior analyst from the economic intelligence unit in beijing, if the forecast for 6% growth is on track for this quarter. well, we forecast the gdp growth can reach as high as 6.9% for the first quarter, and for the entire year, we anticipate will reach 6.6%, higher than the official target. you are quite bullish at 6.9% for the quarter,

and 6.6% for the year. but there are problems in the chinese economy, particularly the rising credit risk, which is now creeping towards 300%, most of it concentrated in the corporate sector. yes, exactly. we still think it is the biggest risk in the chinese economy, and according to one of our latest white papers, just released, on the supply—side reform, in fact, the state—owned enterprises, the soes, debt level has become a historical level. and we still do not think there is any effective solution yet to conquer this problem. and actually, the major measures to tackle that issue, an equity swap, so far we think is pretty much a failure. could this get out of hand, and rising housing property prices which could be in the midst of, potentially, exploding? yes, there is a risk for that. and that's why we're not so optimistic on the economic growth in 2018. in fact, we think there might be a hard—landing equivalent scenario

in 2018, with a growth of 4.5%. and that's because the central government, we think, will take some voter moves to deflate the bubble in the housing market. in the aftermath of world war two, widespread devastation of japan brought a desperate need to rebuild communities. out of the rubble, radical new ideas had emerged of reinventing the traditional japanese house. we have been on tour of a new exhibition in london that traces the origins of the country's architectural design. it really feels like the end of the second world war injapan really opened a new era of the most fascinating investigation in the field of architecture. there was such a mood

to reconstruct and rebuild houses and housing for people. the country has been massively bombed by the us forces, so the country was in a state of shock, a state of trauma. it was really this idea of how do we construct our lives, how do we reconstruct our tradition, how do we face our history? there's, like, several rooms split and scattered in the garden. it does not really look like a house, it looks like a city. it looks like a little plot of a little village inside tokyo.

there's no barrier that separates the house from the outside. it's like going up on a treehouse in the forest. it has a very kind of charming, lovingly crafted structure. this is where the tea ceremonies take place. a visionary architect who works with traditional techniques and carpentry. he's using a technique of shard wood, which has been used for centuries. i think the big lesson we learn from japanese architects is that the nature, the environments, the animals, the weather — the humans should not only be at the centre of everything. you have been watching newsday. stay with us. good morning. the forecast is one

that benefits those on break. not much rain around. but some dry and quite sunny weather to enjoy at times. turning warmer after a chilly start of the note will still state rusty, especially in the south. and quite cold out there at the moment. as we start the day we have high pressure to the west of us, low pressure to the west of us, low pressure at the wood east, the northerly pressure bringing cold are not just to us northerly pressure bringing cold are notjust to us but northerly pressure bringing cold are not just to us but to northerly pressure bringing cold are notjust to us but to a good part of northern and eastern europe as well. now, most will start dry and bright across the northern half of the uk. so let's stop the forecast for easter monday hit. there may be one or two showers across parts of scotla nd or two showers across parts of scotland but a brighter day to begin with across northern england and indeed northern ireland. northern ireland should they dry throughout. but showers and rain, sleet to lower levels, sleet and snow in eastern scotla nd levels, sleet and snow in eastern scotland will drift away southwards through the day, followed by much, much sunnier conditions. whereas further south we start off with the cloud, and maybe the odd spot of

light rain and drizzle. parts of wales, midlands, into the south in particular. there will be very few showers through the day. most will avoid them. if they do come your way they will be fairly fleeting. and notice how the clouds break up, more sunshine developing through the afternoon. so again, just about across—the—board, more afternoon. so again, just about across—the—boa rd, more of afternoon. so again, just about across—the—board, more of you will see the sunshine on easter monday they needed through monday. these are the temperatures to finish through the afternoon. either winds further south in the sunshine, should feel reasonably pleasant. we finish the day with lots of showers in northern england, and they will drift down the eastern areas to take us drift down the eastern areas to take us through the night and into tuesday. as they ease off, the sky is clear, the windfall that little bit lighter. temperatures will plummet. those of you in the northern half of uk it will be the cold est northern half of uk it will be the coldest night of the week. away from the towns and cities, temperatures -52 -7 in the towns and cities, temperatures —52 —7 in some parts of scotland. most just about avoiding frost across the south. probably a bit too much breeze into tuesday for could bring the odd shower and we could see the odd spot of rain in the hebrides a bit later. but for the commuters a cold start to tuesday,

but for those on holiday it is looking like a good day. most places dry, with lots of sunshine. a bit of a fresh spring day, but that sun is strong enough to make it still feel reasonably pleasant. then, as we go through wednesday, high establishes itself. across the southern half of the uk. we will see westerly winds pushing into the south of scotland. that will bring the cloud, the odd spot of rain, that will push into parts of northern ireland as well, keeping the temperature is a peerage wednesday morning. but further south, this will be colder start to the week. one or two you could get down to —6 minus seven. couldn't rule out the odd shower to the south and east, but most places will be dried fairly sunny. goodbye for now. this is bbc world news. our top story. turkey votes, by a slim majority, to give the president significant new powers. president erdogan told a jubilant crowd that the country has opened a ‘new page' in its democracy. but opposition leaders have questioned the legitimacy of the vote. president trump's national security
