this is business live from bbc news, with sally bundock and ben thompson. the end of their instagram story — the founders of the photo sharing website leave the firm six years after it was bought by facebook for $1 billion. live from london, that's our top story on tuesday 25th september. reports of disagreements with facebook‘s board and a desire to pursue other projects sees the co—founders bow out — we'll have more in a moment. also in the programme: the united states and south korea sign a major trade deal. us president donald trump says the agreement is fair and will benefit both nations. the markets are up. the focus is on

the us federal reserve. and the wait is over. we'll find out why our need for now — with superfast delivery on almost everything we buy — is big business for the firms that help suppliers become smooth operators. and as hotels look to cut costs, they‘ re contemplating alexa—style devices at check—in. but would you want a human — and maybe a longer wait — or a faster, impersonal robot when you arrive? let us know, use #bbcbizlive. hello and welcome to business live. do you want to deal with robots or the human touch? welcome to the programme —

we start with the social networking site instagram. the firm's co—founders have both resigned. kevin systrom and mike krieger started the image sharing site in 2010. they continued to run the service after it was bought by facebook in 2012 for $1 billion. however, there have been numerous reports of disagreements between the founders and facebook‘s board. instagram currently has one billion users and is growing — unlike facebook, which has seen a slowdown. with us now is our business reporter paul blake. sally running through the details. this developing overnight. they are leaving. some reports there was a breakdown in relationship with facebook. the new york times reports

that initially when they said they we re that initially when they said they were leaving they did not give a reason but they have released a statement saying they are focusing on creativity and curiosity. the fa ct on creativity and curiosity. the fact they have departed together has set the rumour mill alight. said that they were growing frustrated with how instagram has been integrated with facebook products. it has been stagnating over the past couple of months and hit with scandals, facebook, which instagram has largely been able to avoid.“ you sell a firm for $1 billion and you sell a firm for $1 billion and you stay on the board, you are going to have a say but someone else owns it and will run it. it is inevitable that facebook wanted to do what they wa nted that facebook wanted to do what they wanted to do. exactly. they are looking at it as a place where a lot of advertisers want to be able to tap into that young markets. facebook sees it as part of their

growth strategy going forward and they want to integrated further with that core product. they have done things like try to integrate the way photos are assured from instagram to facebook and away notifications are handled and stories are handled. reports coming out of silicon valley in tech publications that the two founders who are have grown frustrated with some of that integration, with the way that facebook is trying to use instagram to drive people back to its product. what does that the life cycle of these products? they seem to take off overnight and then something else comes along and still is the crown. there is a danger that if they do not come up with new ways of developing things we get bored and move on. exactly, and tastes change and technology moves on. instagram

became about sharing moments, interrupting dinner sometimes to share a story or a moment. instagram started when it was bought, it had less tha n started when it was bought, it had less than 50 million users, today it has over 1 less than 50 million users, today it has over1 billion. it seems to be on an upward trajectory. facebook will see it as growth of its core product. we will keep an ion that. details of the departures of the two founders of instagram. let's take a look at some of the other stories making the news. drugmaker novartis says it will cut about 2,200 jobs in switzerland over the next four years as it consolidates production and moves jobs elsewhere to boost profits. the firm's chairman has said the company is planning to streamline its worldwide production to help cut costs. the swiss company now has about 13,000 employees in its home country. ford is looking at speeding up plans to build more of its cars in china

amid the growing trade war with the us. the firm's vice president says the dispute has made us exports less attractive and that he does not see any easy resolution between the us and china. more than $650 million was stolen from british bank customers in the first half of this year. industry group uk finance says almost $200 million was stolen in so called push payment scams, where customers are tricked into sending money to another account. the rest was unauthorised fraud, including the theft of bank card details. president trump has signed a revised trade pact with south korea. it's the first such deal finalised by mr trump, who's promised to overhaul america's trade relationships.

the president hailed the changes as a very big deal. dr rebecca harding is the founder and chief executive of cori—olis technologies, she's an independent economist specialising in trade finance. she joins us now from the business newsroom. what do you make of this deal? you have to look at the deal in the context that it has been brokered. this is area statement of the deal that was in march this year when the us tried to impose tariffs across the world. south korea went in with exemptions because the us is a big market for south korea, 65% of exports go to america. they said let us exports go to america. they said let us not have a tariff, let's have a

quarter. this is to some extent a political move because it is reinstating some of that. president trump healing this as a big deal, he is keen to point out he can do these big trade deals. even though he is mired about a trade deal with the eu. he is fighting the midterms and he is thinking about the next presidential election. donald trump is the deal maker and he likes to see success saw his strategy at the moment is to say we are prepared to be more flexible on this deal. we will do some deals to be able to create an appearance that we are open for business and we are doing trade deals. forgive me when we talk about south korea being a small market, he is mired in that trade war with china, the worlds second largest economy, with the eu, and

concerns over what deal he will get with japan, and yet he is healing a deal with south korea which is small. this is a small deal for south korea and even relatively small deal for america but he south korea and even relatively small dealfor america but he is saying we are in the business of making deals with people so we are not starting from the position we are not going to make a deal, so it is throwing down the gauntlet to china. what happened with china is china. what happened with china is china said they do not want to resume negotiations at the moment because they have had sanctions imposed because of military trade that has gone on between china and russia so there is sanctions on at the moment. they have called the american ambassador and said they do wa nt to american ambassador and said they do want to resume talks and that means it is very important for the us to look as if it is trying to broker deals elsewhere. all about the appearance. yes. good to hear your thoughts. we have talked about deals being

done between south korea and the us. the south korea markets closed today for a public holiday as was hong kong. this is europe. a mixed picture. we have been trading for a0 minutes. some of the big moves in london, we have next shares up, they came out with great figures for the summer season came out with great figures for the summer season and have lifted their guidance for the full year and then other companies like card factory whose profits are lower. retailers very much at the forefront in london. there is a big event going on in washington. one choose the investors will be playing calls attention to nike. many analysts are expecting that despite the departure

of several key nike executives as a result of sexual harassment allegations the company will be reporting an increase in profits and sales. 0ne reporting an increase in profits and sales. one of the things driving that increase is the decision to appoint a former nfl player as one of its brand ambassadors for its anniversary advertising campaign. the decision was initially seen by some is quite controversial because he had led the charge by many nfl players to kneel during the national anthem at the beginning of nfl playing, games. that seems to have paid off for nike with sales increasing by 30% in september as a result of the company's decision. joining us is shaun port, chief investment officer at investment management company, nutmeg. two big things on the radar. what do we expect from the fed? expected

they will raise interest rates on wednesday and in december. the market is focused on what happens next year, how far interest rates are going to go up. that is fixating markets. the us economy is running red hot at the moment with wages accelerating so challenging times. fixating markets, they have been talking about this for a time, everybody hangs onto every word and sometimes are disappointed. yes. we read every single word. the central bank is very subtle. with language. it is much shorter than it used to be, the message. we will about hear what the fed thinks about increased ta riffs what the fed thinks about increased tariffs so that is going to be crucial for markets. what could derail it is inflationary pressure, the oil price is up. some are saying

it is $100 a barrel in the u. acne year. the market has tightened. despite the us increasing shell production. with iranian sanctions against iran coming through that has 200 million barrels a day that could be at risk. 0il 200 million barrels a day that could be at risk. oil prices will carry on going but because you have the us producing shell oil that is going to keep a lid on prices. we are not going to see $100 a barrel any time soon. going to see $100 a barrel any time soon. when you go to the an a hotel do you think a human or add robot? as fast as possible. you are a robot. totally. if you use will tells a lot you just want to get in. the human touch. you want to talk to them about your cup of tea and your newspaper. we can talk about this later. will tell companies trying to

pretend automatic check—in. so many of you getting in touch. it could be a female thing. mars and venus. maybe. still to come: we'll be talking to the firm that's helping big brands speed up their operations. we will discuss what they need for no means for businesses. —— now. i mentioned that next shares were up nearly 9%, we don't say that often. this summer's heatwave led to stronger—than—expected sales at next in the first six months of the year, the clothing retailer has reported this morning. as a result, next is raising its profit forecast. michael hewson is the chief market analyst at traders cmc markets. good morning, michael. how often do

we talk about some on raising their profit forecast? not often? indeed. you had to put this in context of the profits warning issued by next injuly, they expressed pessimism that the bump in q2 sales that we saw in the summer would carry on into august and september. that has actually transpired. first half profits came in below expectations as £311 million, but they have raised their full—year guidance from £770 million to £727 million due to a better—than—expected performance in august and september. do you think they have that right? you might think it is a silly question, but just because might think it is a silly question, butjust because they had a good august and september, who knows what will happen in the next 12 months? sally, i would agree. i think they are being a bit optimistic, but they have significant cost control measures in place. 0ne

have significant cost control measures in place. one of the things i have noticed is profits were down 2196 in i have noticed is profits were down 21% in retail stores, online is up 23%, they have talked about increasing floor space but they are increasing floor space but they are increasing the number of concessions, which are cheaper to run, and closing more and more bigger stores. i think cost control at the forefront of the expectation that profits will come in better than expected. michael, you are a on business live, do you like a robot or human at hotel reception? is it depends on where the shorter queue is, if the shorter queue is that the robot, i will go there! iam will go there! i am with michael! kim says wider ‘s life had to be arranged around rush, rush, rush to save five or ten minutes? —— why does life? sally: it is all about smiling, nice to see you, what can we do to help you?

ben: but it is about the queue. sally: but we are in such a hurry. it is true on this show all the time! back in a moment! your‘re watching business live — our top story... the co—founders of instagram decide to leave the firm, after reports of a disagreement with facebook‘s board — who bought the company for £1 billion in 2012. six years on, they are off. getting products where you want them, when you need them is crucial for any business. and also for the individual. we might not often think about this, but it is all about the supply chain. somebody has to design it, it is crucial to any business model. a recent survey of people working in supply chain management found that 80% believe the digital supply chain will dominate their business model within five years. and 63% said hiring and retaining a workforce skilled in supply chain management

is their biggest obstacle. well, one company that is working to support businesses with their supply chains is llamasoft — whose clients include unilever, michael kors and ikea. llamasoft is based in michigan in the us and has doubled employee count in last three years to nearly 500 people. and joining us is its chief executive, razat gaurav. nice to see you, welcome to business live. let's be really clear from the beginning, lots of people don't really appreciate supply chain management. i certainly don't, you just assume you order something and it arrives at your house or workplace. somebody has thought about this, designed it, but processors into place. what is it and how would you go about it? there isa and how would you go about it? there is a tremendous amount of complexity that happens in the back rooms and the value chain behind the customer fulfilment, the order that you get

in your home or store. it starts with the raw materials all the way into production and manufacturing, into production and manufacturing, into the distribution network and ultimately to the transportation network into the retail store or the consumer's home. there is a lot to design in terms of locations, physical infrastructure, the inventory levels you need to be carrying, what the production plan should look like, what is your warehousing operation should look like, what your transportation routes should look like. there is a lot to design and plan in orderfor that product to be there at the right time in the right quantity. you have been working in this business for around 20 years, you area guru, business for around 20 years, you are a guru, you have written books about it, supply chain for dummies among them. you have started working as the boss of llamasoft within the last five months. you must have seen radical change, because we demand things, we order something in the

morning and wanted in the afternoon. expectations and technology have both radically changed. consumer expectation is the biggest change. there have been generational shifts. 0nline shopping has become prominent and prevalence. in the background, da rter and prevalence. in the background, darter is more readily available as well —— data is more readily available. competing horsepower is enabling us to monetise that data in ways we have never have been able to dream of before. we think about the amazon model, if you get it right can be very lucrative. i spent some time recently at their new warehouse in essex in the uk, entirely run in many respects by robots, kicking things off shelves, bringing them back to distribution. all well and good if you are the size of ours, but what if you worry small firm selling a few things a day, how can

you hope to compete without that budget? there are economies of densities and economies of scale in the supply chain. there are suppliers who are able to bring the density to you. there will be third—party logistics companies that we work with able to aggregate networks and operations from multiple small companies and can bring about sophistication to the table. not everything has to be about robots, it is a consistent theme this morning, lots of it is making decisions, smarter decisions about allocating inventory in distribution centres, stores and manufacturing plants, where should you be sourcing? that is a big scene right now with the trade and tariffs stock. munyer claims is unilever, nestle, ikea. huge, global suppliers. munyer claims is unilever, nestle, ikea. huge, globalsuppliers. —— among your clients is unilever, nestle, ikea. how are they preparing

for the difficult to predict scenario called brexit? it has been very busy for us because there is a lot of uncertainty, and where there is uncertainty you have to play out different scenarios. we help our customers take their data, their network, and create a digital twin. their physical network, create a digital twin. then they played a different scenarios, but the reality is in the absence of clear policy direction, so it could be to do with brexit, the debate between china and the us, mexico and nafta, there is a turn of uncertainty and sometimes these duties and tariffs can account from anywhere between 10% and a0%. companies are waiting and watching, playing a different scenarios, but they are waiting for making any big capital investment decisions. as a result of that, inventory is a

creeping up, which is not very good for the economy. really nice to see you, razat, thank you for explaining about. razat gaurav, chief executive of llamasoft, thank you. here is how to stay in touch. stay up to date with all the day's business news as it happens on the bbc‘s business live page. there's insight and analysis from our team of editors right around the globe. and we want to hear from you, too. get involved on the bbc‘s tbusiness live web page at bbc.com/business. on twitter, we're @bbcbusiness, and you can find is on facebook at bbc money. —— you can find us. business live, on tv and online. what you need to know, when you need to know. what other business stories has the media been taking an interest in? shaun port from nutmeg joins us again to discuss. let's talk about this story, what is being proposed? workers at marriot have been talking to their union and

striking and not just have been talking to their union and striking and notjust about higher wages and better safety but also about getting protection against advanced technology taking their jobs. it very interesting step from the union to try to protect against future technology taking awayjobs. taxi drivers have the same issue with things like uber, new technology changes the way people do jobs. this is about whether customers would accept... we have already debated whether we would like it. we check in automatically with airlines, and would love to see it in some areas. i don't want to spend an hour waiting for car hire atan spend an hour waiting for car hire at an airport. consumers will really win. ruth says she is with me, maybe it is a male/ female thing. human receptionist 100%. if all thesejobs female thing. human receptionist 100%. if all these jobs are taken over by machines, who will be able to afford to stay in a hotel? lula says most hotels require id,

how would they confirm that? i assume you might have logged all your details. artificial intelligence can deal with complicated queries. suggesting maybe if you are a complicated customer... tyler says a human every time, who wa nts to tyler says a human every time, who wants to convert with a machine with no personality or emotion? jill says 100% human being, i appreciate the need for speedy checkout. business people will probably prefer this. often there would be somebody in the lobby to help you with the more complicated query, if you do not like your room, probably there will be somebody to help? advise it is like a fast—track supermarket, you can do it yourself but there will still be people. -- it is like a fast—track supermarket, you can do yourself but there will still be people. iam still be people. i am still voting free humans every time. this is business live. back tomorrow, thank you. it was another chilly start to the
