Thats could come later. Well assess what the markets make of today. The pound is moving and well get the inside track on the Fastest Growing publishing market, audiobooks. Its a Global Industry valued at 3. 5 billion and the boss of the Biggest Company in the business audible is here. And so let the negotiations begin as the Brexit Process formally gets underway how do you think it will go . A good deal, bad deal or no deal . Let us know. Just use the hashtag bbcbizlive. Welcome to the programme. Nine months after voting to leave the eu today begins that process. It kicks off two years of negotiations. And for businesses in the uk and across the continent its likely to be two years of uncertainty and preparation. In the financial heart of the country, several big banks have threatened to move staff overseas if they dont get the brexit deal that they want. So whats at stake for the city . Latest figures show it contributes 159 billion a year to the uk economy it employs almost 1. 2 Million People in uk. It also contributes a Trade Surplus of nearly 73 billion to the uks balance of payments. Thats to say it brings lots of money into the country. But the eu also relies on the uk. 6. 6 trillion worth of Financial Assets are under management here in the uk. Thats 37 of the european total. Well, one reason its so high is whats known as passporting. Licences that let banks and other Financial Firms do business elsewhere in the eu. 94 of all the licences to do that are held by uk registered firms. So how will today shape up . Theo has the details. Run us through the day for what will turn out to be a pretty historic day . Also a carfully choreographed day, ben. Theresa may is meeting with the cabinet at Downing Street. Later on, she will head to the Palace Of Westminster to the House Of Commons for Prime Ministers questions and it is after that that she will stand up in the House Of Commons to make that long awaited speech saying that she has triggered article 50 of the Lisbon Treaty which will set off the process of britain leaving the European Union. As you would probably know, if you have been to any Dinner Parties around the uk lately, this is a controversial subject so she will make conciliatory remarks. She will say she promises to represent every person in the whole of the uk during the negotiations. Now, whilst she is doing that, our man in brussels, the uks permanent representative to the European Union will travel to the europa building, the headquarters of the european council, he will meet with donald tusk and he will hand over the letter itself. It has been signed. After that, there maybe a short formal acknowledgement that article 50 has been received by the council which will appear on their website and donald tusk may well tweet. The Chief Negotiator is expected to tweet during the day and the European Parliament u the heads of the political groups in the European Parliament, theyre going to be meeting during the day and theyll come out with a Press Conference later. So all of this is very carefully choreographed. What happens after that is within 48 hours the European Commission will draw upa hours the European Commission will draw up a Negotiating Mandate, a d raft draw up a Negotiating Mandate, a draft Negotiating Mandate which the 27 other members of the eu will have to endorse and give permission to the commission for. Theo, thank you very much indeed. That gives us a sense of the timeline. With us isjohn longworth, former Director General of the British Chambers Of Commerce but he resigned from thatjob to campaign for the uk to leave the eu. Iimagine you i imagine you are excited about this process and it formally beginning, something the Prime Minister was at pains to say late yesterday was, she is looking to broker a deal that will benefit all. High hopes. What are you hoping the outcome will be . Well, benefiting all, of course, means doing whats best for britain and were fortunate that the real benefits of brexit which there are many, can be crystallised entirely by the uk. Entirely independently of the European Union, and actually independently of the Single Market and the customs union. We have to leave those two institutions in order to get the benefits of brexit. So whatever happens in the next two yea rs, so whatever happens in the next two years, britain can make itself the best place in the world to do business which will boost the economy and which will solve a problem of the Deficit Problems and the balance of employment will improve. So actually, the uk is in a uniquely good position to have the best dealfor britain. Uniquely good position to have the best deal for britain. Even uniquely good position to have the best dealfor britain. Even if uniquely good position to have the best deal for britain. Even if we dont get a Free Trade Arrangement with the eu because a Free Trade Arrangement with the eu is actually icing on the cake, it is by no means important as important as the other things that we can do. Lots of ifs and abouts, arent there, john and the chancellor at there, john and the chancellor at the time was campaigning for remain, of course, called it a leap into the dark. A leap into the unknown and it really is, isnt it . It has never been done before. It is unprecedented and we dont know how its going to turn up. We dont know what will happen in the negotiations. The main part is around sorting out the administrative Arrangements Twoon the uk and the eu, customs union, Border Control and so on. Thats really very, very technical and a process that we can readily go through. The rest of it actually is very much known because if it is in oui very much known because if it is in our gift to actually crystallise those real benefits, removal of the cap, and repatriation of our net contribution and fisheries and deregulation, all the things that will boost our economy, those are in oui will boost our economy, those are in our gift, it is not a leap into the unknown in that sense because we can do the things we want to do. Unknown in that sense because we can do the things we want to dam unknown in that sense because we can do the things we want to do. It does depend how the negotiations go. The Horse Trading which will go on for months to come and brussels made it clear it will not be persuaded, it will not be giving the uk an easy exit, it will be a very costly exit and for each particular sector and industry in the uk, it will mean very Different Things . Well, there is lots of administrative stuff to be sorted out, there is no question about that. There will be a lot of heat and light and the eu will be upset about it because it is the lifeblood of the commission. There is so much more to discuss, john.

It is interesting to see new developments and keeps us on our toes. I guess what is interesting is which markets will react. You can argue it both ways. What we will be looking at as ben mentioned is the currency. The currency is the one that seems to be most sensitive to the brexit and whether there will be any kind of deal and whether there will be any kind of dealand in whether there will be any kind of deal and in which Case Sterling will probably go up. If both sides stick to their current Negotiating Stance it will probably go down actually. What i find really interesting when we talk about arle 50, markets normally love any sort of rumour, any speculation and theyll go hay wire as a result. Here, we have got lots of speculation and lots of uncertainty and markets are like, we will see how it plays out . You had the initial move down post the 23rd june vote.
