good morning. it is 7:00am in singapore, midnight in london and 2:00am in the morning across turkey, where a referendum has granted the president 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. our correspondent mark lowen has been outside the ruling party's headquarters in ankara. earlier, he had this to say about the result. extremely close, and not the resounding victory that erdogan originally thought he could get. he decided to go for this referendum of the back of the failed coup last year, in which his popularity was riding very high, at about 70 or 80% in the opinion polls. he thought he could ride that wave of popularity and geta could ride that wave of popularity and get a resounding 60 mandate in this constitutional

change. as it happens, it was extremely slim. the election officials say it was 51 point eight to 48.7, yes to know, the opposition disputing it, and vowing to challenge the result —— 51.3. the opposition going to challenge it at the courts and the electoral supreme board. so you have one side of a country which is jubilant and the other side of the country that says that they will not even accept what they called for real results. so in a sense turkey's stability in the short term, it is the worst possible option. the stability that turkey craved, it still seems very far away, and really tonight this country is more polarised than ever. and how has the vote broken down country—wide? because obviously ankara, istanbul, normally pro— erdogan, they voted against. yes, and that was a surprise, especially istanbul, which is erdogan‘s home city, the city he is narrower. he has a huge support base. the fact that went for know, as well as the

city ankara, but even more several other big cities also went for no, that really is very telling in terms of the demographic split in this country. the smaller cities, the more rural areas, they voted for yes. they are... they have poorer, more pious, more conservative turks, who seek erdogan as their voice, and what was a secular country. officially, constitutionally, it still is, but he has basically destroy that. and that on the other side of the country, the more westward looking, cosmopolitan turks feel that mr erdogan has destroyed what was left of turkish democracy. they voted no. and so that is why this country is so deeply split. really, when you look at how the vote divided, and the fact that one side of the country is simply not accepting it, in a sense it is pretty ha rd not accepting it, in a sense it is pretty hard not to conclude that turkey feels lost at the moment. 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. a rescue operation had begun in north—western iran, after heavy flooding. according to state media at least 30 people have died, with many still missing. floods are affecting five provinces in the north of the country, with the worst reported from the mountainous north—east. the authorities have issued warnings of more floods in the next few days, as more torrential rain is expected. pope francis has asked for the leaders of the world to find the courage to end the spread of conflict and to halt the arms trade. during the easter celebrations in rome, the pope prayed for peace, especially in the middle east and africa. he ended the easter mass in front of thousands of pilgrims in st peter's square

with the traditional blessing of the city of rome and the entire world. there has been an intriguing discovery in a secret tomb beneath this church in central london. the bodies of five former archbishops were found during renovation work in st mary—at—lambeth church, which is next to lambeth palace, the residence of the archbishop of canterbury. builders found a hidden crypt containing at least 20 coffins, including one belonging to richard bancroft, who became archbishop in 1604. the trump administration has reiterated its determination to take action against north korea, following another missile test by pyongyang. on a visit to kabul, the white house national security advisor, general hr mcmaster, said the president is looking at a range of options, including involving china, if north korea refuses to scrap its nuclear weapons. well, this latest missile test, it

just fits into a pattern of provocative and destabilising and threatening behaviour on the part of the north korean regime, and i think there is an international consensus now, including the chinese, and the chinese leadership, that this is a situation that just can't chinese leadership, that this is a situation thatjust can't continue. and the president has made clear that he will not accept the united states and its allies and partners in the region being under threat from this hostile regime, with nuclear weapons. the latest defiance from pyongyang came on sunday, when what is thought to have been a medium—range missile was test—fired from the east coast port of shinpo. although it failed soon after launch, the test is being seen as a provocation, coming shortly before the us vice president, mike pence, arrived in south korea. our correspondentjohn sudworth is in the north korean capital, pyongyang. 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 yesterday, 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. our commitment to this historic alliance with the courageous people of south korea has never been stronger. and with your help, and with god's help, freedom will ever prevail. 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. let's bring you right up to date with this story, with our correspondent in seoul, stephen evans. this range of options which is being discussed needs the cooperation of many players. you have the south koreans, the americans, and president trump even wants to bring in the chinese. 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 ofa 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 currency manipulator when they're working with us on the north korea problem? will they're working with us on the north korea problem ? will see they're working with us on the north korea problem? will see what happens. so the policy is put more pressure on china, to put more pressure on china, 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 is pretty well the obama 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. thank you so that remains to be seen. thank you so much for the update. 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. also on the programme: the president won't like this.

it is donald trump cast asjudas during easter celebrations in mexico. 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 will be chasing her new world best time for years to come. quite quietly, but quicker

and quicker, she seemed just to slide away under the surface and disappear. this is newsday on the bbc. i'm rico hizon in singapore. i'm kasia madera in london. our top stories: yes campaigners in turkey celebrate as they claim victory in the referendum. president erdogan says changes to the constitution will now go ahead. another warning to north korea. president trump's national security advisor says the us is working with its allies and china, on a "range of options" let's take a look at some front pages from around the world. 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. now what stories are sparking

discussions online? yes — it's once again a story about donald trump — although not the president himself. instead, it's these pictures from mexico of mr trump being cast asjudas during easter celebrations. it didn't end well for the satirical creation — it was packed with fireworks, and quite literally blown apart. donald trump's insistence that he will build a wall along america's border with mexico has clearly affected his popularity there. 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've 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 were such a mood to reconstruct and rebuild houses and housing for people. the country has been massively bombed by the us forces and the country was in a state of shock and trauma. there was

really this idea of how do we construct our lives? how do we reconstruct our tradition, how do we face our history? there were several rooms split and scattered in the garden. it does not really look like a house, it looks like a city, like a house, it looks like a city, like a little village inside tokyo. there is no barrier that separates the house from the outside. it is like going upa house from the outside. it is like going up a tree house in the forest. it has a charming and lovingly crafted structure. this is where the

tea ceremony will take place. a visionary architect who works with traditional techniques and carpentry. he is using a technique of shard would that have 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 humid should not only be at the centre of everything. 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 — with the figure to be released in the next few hours. so what can we expect? a senior analyst from the economist intelligence unit joins us live from beijing to talk

about china's priorities. everyone is waiting and watching for these first—quarter gdp numbers. we heard someone a couple of months ago saying that growth could be around 6.5% this year. but for the first quarter will it be below that within that range? well, we forecast it 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. 6.9%, that is quite bullish. 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 brisk in the chinese economy and according to one of our latest white papers just released, in fact the state owned enterprises, that 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, we can get a failure. could this get out of hand and rising housing property prices which could be in the midst of that, potentially, exploding. yes. there isa potentially, exploding. yes. there is a risk for that. that is why we are not so optimistic on the economic growth in 2018. in fact, we think there may be a hard landing corporate scenario in 2018 with a growth of 4.5%. and that is because

the central government, wheezing, ta ke the central government, wheezing, take some voter moves to deflate the bubble in the housing market. can it be controlled by the government? we think we are pretty much there because so far the first year, is the housing price has gone out control. if there are no restrictive policies and those prices could go even further up. in china, the housing policies are diverging and so was housing policies are diverging and so was the crisis. in lower tier cities is that it is hard to convince people to purchase houses but in the first tier cities they are gone in an instant. there is no good measure of the moment control housing prices whatsoever. many risks still in the chinese economy. thank you very much forjoining us.

we are all looking forward to the gdp number coming out from china and several hours. you have been watching newsday. stay with us — we will be taking a further look at china and the release of its growth numbers for the first quarter. and before we go, let's take a look at these pictures of a record breaking attempt to gather together people dressed as the silent movie star charlie chaplin. theyjoined bowler hats and walking canes at the charlie chaplin museum in switzerland — paying homage to his best known character, the little tramp. in all there were 662 chaplins on view — men, women and children. the comic actor spent the last years of his life in switzerland. and yes, they did set a new record. that's all for now — stay with bbc world news. a few showers continue in the

builds in across southern areas as we go into tuesday night and wednesday. as it pushes southwards we allow more off the atlantic in the form of cloud, keeping temperatures appear to take this into wednesday, clear skies in the south and a cold start. the trainer of the rest of the week, it will feel warmer by date of frosty nights will still be a feature of and will ta ke will still be a feature of and will take effect across the southern half of the uk. i'm kasia madera with 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 advisor has said an international consensus, against what he called north korea's threatening behaviour, now includes china. and this video is trending on bbc.com. these images are from mexico. it is an effigy president trump as judas, for the easter celebrations.
