a university lab is working on fillings that heal your teeth. could this mean fewer trips to the dentists in the future? that's in half an hour, here on bbc news. hello, and welcome to the elysee palace. we arejust hello, and welcome to the elysee palace. we are just outside, rain has been pouring throughout this inauguration ceremony on and off, but the skies were blue for that outside parts, a 21 gun salute. emmanuel macron is france's youngest ever president at the age of 39. emmanuelle macron was greeted

by onlookers in light rain as his motorcade approached the elysee palace. at 39 he is france's youngest leader since napoleon. he faces a series of daunting challenges, including high unemployment, a sluggish economy and terrorist attacks. he walked down the red carpet to meet the man handing over the reins of power, francois hollande. the body language between the two men was warm. mr macron was previously an economy minister under the socialist government before he left to set up his movement, recently renamed republique en marche a year ago. before the inauguration ceremony they held a private meeting in which mr hollande handed over the codes needed to launch france's nuclear weapons. afterwards they greet mr macron‘s wife brigitte, who had arrived earlier.

to much applause, mr macron bids his predecessor goodbye, who in turn wishes him good luck with the task ahead. it is a week since mr macron was declared the victor over the far—right leader marine le pen. he spoke of the need for a strong france, trying to spread the message of unity after a divisive election campaign. translation: i will convince our citizens that the power of france is not declining, that we are on the edge of a great renaissance because in our hands we have all the assets which make, and will make, the great powers of the 21st—century. to do that i will yield in nothing on the commitments made with respect to the french people. everything which gives figure to france and prosperity will be implemented.

work will be made freer, companies will be supported, initiatives will be encouraged, cultural education, which gives rise to emancipation, creation innovation, these will all be at the heart of my actions. vive la republique, vive la france. mr macron‘s election victory ends the decades long dominance of the two main left and right—wing parties in france. whether he will be able to bring the change he seeks will depend on next month's parliamentary elections. as yet he has no mps. while we have been outside of the elysee palace, in all sorts of weather, journalists from all over the world and very tight security around here, a handful of journalists were inside into the ceremony itself. the paris bureau chief of the economist was allowed m, chief of the economist was allowed in, andi chief of the economist was allowed in, and i was speaking to her about

that experience. it was very moving, it is quite an intimate setting, in the ceremonial room where banquets ta ke the ceremonial room where banquets take place and the inauguration of president's. only about 500 or 600 people are there. some are official representatives of the presidents, the constitutional court, but also tea m the constitutional court, but also team members who have been with emmanuel macron throughout the campaign. some very young, a solid group of people who believed in him from the start. there they are, inside of the elysee palace welcoming the new president. the meeting between the outgoing and incoming presidents went on for far longer than expected 7 incoming presidents went on for far longer than expected? yes, the poor guests waiting for the new president to arrive downstairs were getting impatient, but the two know one another well. emmanuel macron was the deputy chief of and economic adviser. they had a lot of memories to share, one imagines that they we re to share, one imagines that they were driving on that as well as

official business of passing on nuclear codes and official business. it seems even before the inauguration was underway, the warriors and thoughts had turned to the challenges ahead. —— worries. the things emmanuel macron has to do in order to carry out what he has pledged, how big are those challenges? enormous. he has raised expectations because of the promises he made during the campaign about transforming party political life and across the political divide. transforming, his word, notjust reforming the economy. starting to encourage entrepreneurship and risk—taking in a part of the french culture. he has raised expectations hugely, as well as his plans for europe. there are big expectations on his shoulders and a huge responsibility in terms of keeping this nation safe at a time of huge political threat. economic challenges, in particular, how big

are they? we saw the resistance when he tried to bring in his own reforms as economy minister. it was massive outside parliament and within? it's a big question going forward, we will look at it over the next few months after legislative elections injune and in august when he wants to pass the labour bill. it will be a test of his ability to get this through. you still need parliamentary approval for this decree, and it is a huge test for him. he has never had that experience as when he was the minister he was not on the front line having to defend this against the unions, that was the job of the prime minister. that's when we will be able to see if president macron has what it takes to push against resista nce has what it takes to push against resistance in france, or if he will wa nt to resistance in france, or if he will want to be one of those leaders who, in the end, bowels —— bowels will bow down. emmanuel macron is

currently by the arc de triomphe shaking hands with that —— with army veterans. at the tomb of unknown soldier he laid a wreath. we saw him do the same thing for victory in europe day, a has a lot of challenges and after the ceremony, he said in his speech that he will be starting his work this evening. studio: thank you. all sorts of weather in paris this morning. sunshine and rain. in other news now. . . friday's cyber attack hit 200,000 victims in at least 150 countries according to the head of the european union's police agency. europol‘s director, rob wainwright, has warned that he fears the number will grow when people return to work tomorrow. at europol we are running around 200 global operations against cyber crime each year, but we have never seen anything like this. we have seen the rise of ransomware becoming the principal cyber threat i think,

but this is something we haven't seen before. the global reach is unprecedented. how many countries now? the latest count is over 200,000 victims in at least 150 countries. those victims, many of those will be businesses, including large corporations, like fedex in america. and these are different institutions? many different institutions, it is certainly not a uk only problem. it is an international problem. this morning, the defence secretary michael fallon told andrew marr that the government had identified in its security review that cyber threats were one of the greatest threats to the country. in our security reviewjust over a year and a few months ago, we identified cyber threats as one of the three principal threats and we set aside £1.9 billion to protect us better against cyber and a large chunk of that went to the nhs. but you didn't pay for the upgrade in 2015.

hang on, we are spending around £50 million on the nhs cyber systems to improve their security. we have encouraged the nhs trusts to reduce their exposure to the weakest system, the windows xp. only 5%, less than 5% of the trusts, actually use that system any more and there is money available to strengthen these systems. but you did not pay for them to strengthen that system at a crucial moment in 2015, did you? that was an old system, we didn't want them to use that. we wanted them to use modern systems that are better protected. we warned them and they were warned again in the spring. they were warned again of the threats. by the government, is that what you are saying? we all had to work at this. the nhs wasn't particularly targeted, the same attacks applied to nissan on friday and in other areas of the economy and indeed around the world. but let me just assure you we are spending money on strengthening the cyber defence of our hospital system. meanwhile, most of the health organisations in england

and scotland that were affected by the attack are back up and running, but some patients face continued disruption with six trusts in england still affected. richard galpin reports. this unprecedented global cyber attack hit the nhs hardest, leading to cancellations and delays at hospitals and gp surgeries across england and scotland. but ministers attending a meeting of the crisis response team cobra yesterday concluded that the situation was back under control and the nhs was working as normal again, for the most part. and nhs officials insisted that the disruption was not because they were using old microsoft computer operating systems vulnerable to attack. the nhs has some of the most up—to—date technology in the world. if you look back to december 2015, about one in five devices were using xp but now it is less than one in 20. although the worse may be over for now, several hospitals like this one here in york are warning

that the disruption will continue beyond the weekend. in the wake of such a virulent cyber attack, security experts are calling on everyone to take simple measures to protect their computers from hackers demanding ransoms to unlock their computer files. the first one is to make sure that your security software patches are up—to—date. the second is to employ proper and good antivirus software and the third and most important for ra nsomwa re protection is to back—up your data. but britain was just one of over 100 countries hit by the cyber attack. russia was apparently targeted the most while european telecommunications and car companies were also targeted, as were schools and universities in china. richard galpin, bbc news. let's get the latest from one of the

nhs hospitals targeted in the attack on friday. our correspondent, judith moritz, is outside york hospital. how are they coping? well, they are working flat out to sort this. the it department have been here since friday and are still working behind the scenes to get the computers here act on. they tell me that they have 6000 pcs across this hospital, and 2000 of them, one third, were infected. it gives you an impression of the size of the problem. they have taken a methodical approach to getting through this. they have been trying to return computers back to use but in each department, one at a time, so that every ward and apartment has at least one computer functioning. they have had an impact across different areas, so breast

screening, mri scanning, pathology and radiology. those departments we re and radiology. those departments were affected, with 30 operations cancelled here on friday. some of those departments, like pathology, are back running and are trying to get back to normal but in terms of the knock—on effect and what will happen into next week, there will be a meeting at 2pm here with the managers dealing with this, looking at what to do next and whether they will have to cancel any thing tomorrow as well. currently, advice is that people with outpatients appointments should attend here today and tomorrow, a&e is in use but the advice is to only use it if there is a real emergency. hospitals in the north of england, they say that routine operations scheduled for tomorrow are not going ahead, here they will take the view that later on they hope to get things back to normal by then. thank you. that's the picture in york. another hospital affected

by the ransomware was the royal london hospital in east london. our correspondent, simonjones, is there for us. how is it looking there? this hospital is part of the largest nhs trusts in england. if you go to the emergency department, behind me you will see that they are suffering the effects of a cyber attack. there are handwritten notes on many of the doors, warning people that the it systems a re doors, warning people that the it systems are still down and that they faced long delays. ambulances are still being taken from this hospital to other hospitals where the situation is not as bad. and, they are already planning for disruption tomorrow, because they cannot tell me when this problem is likely to be solved. they are already saying that some appointments are going to be cancelled tomorrow. if you are due to come here you should be contacted by the hospital but they won that they may not be able to get in touch with everyone. —— they are warning.

they are warning to patients that will turn up here tomorrow that they may not be able to have their treatment. to give a sense of how acutely problem is, they are asking gps in the area not to refer people he for non—urgent tests and scans, and ask people like in york to only arrive here if there is a genuine emergency and to use other parts of the nhs like pharmacists or gps, or other an effective hospitals. going to a&e earlier, it is pretty quiet at the moment, there isn't a sense of panic. perhaps people are heeding this warning to stay away. but patients i have spoken to have told me that staff are acting well but have condemned the people behind the attack. simon, thank you. simon jones at the royal london hospital. the latest headlines... emmanuel macron becomes the french

president in a elaborate ceremony at the elysee palace. director of europol has said the number of computers affected by the malware attack on friday is continuing to rise. the conservatives promised a new generation of social housing will be built if they win the election. let's see what is happening in the world of sport... a lot of action this afternoon. liverpool against west ham for one, can tim tell us about it? it's a massive day for hull city. anything other than a win at crystal palace will mean they'll effectively be relegated from the premier league. they're about 15 minutes into the action at selhurst park and they made a terrible start. a bad mistake from andrea ranocchia and wilfrid zaha scored after two minutes. liverpool can move into third with a victory at west ham united. that match kicks off at 2.15. the pressure is coming at the end of

the season, that is how it is. if there isn't pressure you don't go for anything. of course, we have this kind of pressure and we know that all of the competitors in the table are very strong. they can all with double games, but we are also strong. we have a difficult game against west ham and it is very important. how important? we will see. we will be focused already come a bit focused, on ourjob. they are a great side, of course. very electric. recently a way they have been winning their games. we are talking the game against stoke, watford. .. but both are talking the game against stoke, watford... but both of those games had them performing differently. but they are of course a great side. we are expecting a tough game. that is

what you need in this part of the season. it's tottenham's last match at their old white hart lane ground before they move into a brand new stadium the season after next. in the meantime, they'll play their home games at wembley. it's bound to be an emotional occasion when they host manchester united at 4.30 this afternoon. i think that it will be special. it will be special for i think that it will be special. it will be specialfor our i think that it will be special. it will be special for our fans, first of all, the staff and the players. and the people that love tottenham. but, at the same time, i think it will be exciting because we are all excited and we will come to the new stadium. huddersfield are taking on sheffield wednesday in the first leg of their championship play off semifinal. the match kicked off at 12. these sides finished fourth and fifth respectively. and there's not much to separate them so far either. nearly 20 minutes in there at

huddersfield. ian poulter has rediscovered his form at the players' championship in florida. poulter only played 13 tournaments last year because of a foot injury and has slipped well down the rankings, but he'sjust three shots off the lead going into the final round at sawgrass after shooting a 71. americanjb holmes and kyle stanley share the lead on 9—12 under par. to go bogey free out there today, that was incredible. as you said, the only bogey free round of the day. obviously i have kept mistakes of my card, and played very patient golf. i tried to play as sensibly as i could. trying not to take on any silly risks out there. saracens full back alex goode says his side can still improve despite securing back—to—back european titles. sarries beat clermont auvergne 28—17 at murrayfield yesterday to remain on course for an historic double—double of continental and english titles. we have got a young squad, and a

squad that is very hungry to keep getting better and improving. today's performance was really special to be part. everybody was phenomenal. as i said earlier, the attack was brilliant at times. it was a joy to be on the field with the rest of the team, and i think the rest of the team, and i think the great thing is that we will go backin the great thing is that we will go back ina the great thing is that we will go back in a couple of days and look at that, and see where we can get better. that is the strength of the group, that we are constantly looking to improve and get better, and we never feel like we are the finished article. britain's double olympic gold medallist nicola adams continued her 100% record in professional boxing. she beat mexico's maryan salazar with a third—round stoppage in her home town of leeds. it was her first knock out since turning pro. adams is aiming for a world title fight next. that's all sport for now. i'll have more in the next hour, including the latest from the spanish grand prix with lewis hamilton on pole. the royal college of

nursing congress in liverpool has voted overwhelmingly for a summer of "planned protest, followed by an industrial action ballot" if the next government doesn't address pay restraint. our health correspondent jane dreaper is in liverpool for us. jane, can you bring us up—to—date... does this mean we could have nurses on strike? we could, eventually. what is going to happen will probably become known as a summer of discontent. members voted overwhelmingly this morning to hold protests over the summer and we don't yet know what form they will take. we are likely to see banners outside of hospitals, protest marches, that sort of thing. we have also in this resolution that got past year warned the next government that it pay restraint is not lifted,

the 1% pay rise cap in existence at the 1% pay rise cap in existence at the moment, and has been in existence since 2012, that they will hold a ballot on industrial action and strike action. this is a union that has never held a vote on strike action. until the end of the summer, it would be a big move and a big change for the uk's nurses. jane draper, thank you. the conservatives say they'lljoin forces with councils and housing associations to build thousands of new homes for rent if they win the general election. theresa may says she wants to fix a broken market. it's not clear how much money the tories would invest, and labour have dismissed the announcement as spin. here's our political correspondent, iain watson. it is my great pleasure to hand that over to you. mrs thatcher became famous for selling off council houses. but this conservative prime minister is now pledging to help local

authorities build more of them. if re—elected, theresa may would give councils new powers to purchase derelict land and buildings at below market value. housing associations as well as local authorities could then use these to build more homes for rent. some homes would be sold off after ten to 15 years. tenants would have first option to buy and then proceeds used to fund more rented housing. the policy is aimed at voters who might not be traditionally conservative supporters, including some of the million people on housing waiting lists. while the conservatives say thousands of new homes would be provided, a precise figure is yet to be given and they have not said how much extra funding would be given. labour pledges to build 100,000 homes a year for rent and sale by the end of next parliament. the party says that conservative policy is spin, not substance, as some of the details are yet to be revealed. labour says it would raise billions of pounds for public services

with a new tax on financial transactions known as a "robin hood" tax. the party said extending the way shares were taxed would bring in up to £26 billion in the next parliament, if they won the general election. the conservatives described labour's plans as a "shambles". speaking on the andrew marr show, the shadow foreign secretary, emily thornberry, said it's right that all transactions including so called derivatives, are taxed the same. the truth is is that at the moment, we have got a tax which applies when you buy stocks and shares. currently, some people called market—makers, with hedge funds and so on, if they buy these shares they do not pay the tax. i don't understand why that is, but the other thing is that we also think that we should extend this tax to different types of financial instruments. it is a betting on the stock market and will help to stabilise it. many other countries do it. hillary clinton wanted to do it

if she was elected as president, nibley says that she is trying to undermine wall street. the eu is looking at that... it should be done in coordination with other countries to avoid hedge fund managers from moving to paris or dublin, wherever? you want to keep businesses here? i think the house of lords committee on this was interesting, looking at any changes of behaviour and they said they did not think it would be as drastic as some of the doomsayers say that it will. it is a question ofjust tidying this tax up. it does not seem to me to be right you can bet on the stock market or bet on the debts of a company and not pay tax, whereas it you want to invest, you have to pay tax. portugal has won the eurovision song contest for the first time

in the history of the competition. salvador sobral, who is awaiting a heart transplant, lifted the trophy after winning over both the internationaljuries, and the tv viewers. the uk's lucie jones delivered the country's best portugal has won the eurovision song contest for the first time in the history of the competition. he could not believe it. but salvador sobral had just won eurovision. his victory is portugal's first in the contest after 49 attempts. as for the song, amar pelos dois, his sister wrote it and it is very un—eurovision. no gimmicks, no video screens. just a melancholic melody and his charisma and charm. bulgaria came second. portuguese eurovision fans have been waiting for this moment for such a long time. they had grown so used to losing

that winning sparked plenty of emotion. amazing. it will be amazing. it is like a dream come true. flying the flag for the uk was luciejones. a power ballad, never give up on you, placed 15th, our best result for six years. were you aiming for a particular place? no, ijust did not want to come last, so actually i did really well. and, of course, this being eurovision there was weird... there was wonderful... and what on earth was this?! but perhaps it won't be the music we remember.

it's the mischief. during the interval act, a man got up on stage and bared his bottom live on tv. a bum note indeed. an estimated 200 million people will have watched tonight's contest. the show always delivers high ratings. personally, i wish you could have delivered a few more points to the united kingdom. steve rosenberg, bbc news. let's go back to that news about the cyber attack on friday, as we have been hearing, europol said on friday a cyber attack actually hit 200,000 victims, in at least 150 countries. the man who made that warning is rob wainwright, the director of europol. thank you forjoining us. tell us

what you now know and what has emerged about the scale of the attack? it is fast spreading, there isa attack? it is fast spreading, there is a unique characteristic of this ra nsomwa re is a unique characteristic of this ransomware attack, we are used to add europol seeing how ransomware has become a major problem, but we never saw something on this scale. that is because ransomware itself has been combined with one application that allows for the infection of one computed —— to quickly spread to other computers which is why we have seen these numbers increasing all the time. across different sectors across the world, i think the numbers are going up. we have seen a slowdown in the infection rate on friday night after a temporary fix around it. it has been overcome by a second variation that the criminals have released. so numbers are going up.
