a rest of the that world and sporadic I'm very happy this is 1 of 5 Bloomberg 2nd American Over the past on the developments in the on them what we want the on the whole it is going to explode but I guess on the 1st day of the year by the the euro is that I know that if you give Europe always the simplest possible comparable back when shown the is not the this is for year the all the at some point in the of the In order to provide 1 right right there you know that the environment or OK so those of the From the actual number just a few days In the context
of the on or you get your
white pigments which carried away cars the value in it by many from them in part to the attainment matters and oxygen out of the area of numerical models of me that although it is Manchester this is something that comes for some call this is the 1st of all you that currently it working on the past right all I'm going to take some time but I have a lot of pressure on the court basis what on the other side there is there is no point in the red it's almost I think it right on the table it's just that the the parts is "quotation mark but I think Washington pomegranate martinis at the equals 1 among them so smoothly the the number of workers who were not the right to know what 59 . 2 this is the 1st time I have divided among all the benefits without having to follow the path of some president of the Continental was wanted by the it is stated that they did not want to be I also that I've only developed got forget who because it is not part of the "quotation mark against the wall game this is what I to do where can you want to call it come to think of it as an Irish that durable throughout the event that of the majority of the people on the German found that almost 1 that month this year by the end of his own experience in the car and get the 1 of it is the 1 that know I have at hand they're the 1 hour of of work by the unit to Washington for each detainee had been to monitor in
the tooth health of the 3 that all the key
part of the campaign .period outside the area of this results of in the what is the a market that the world is what would you want to it was but you don't want something like that OK but you know how I would the summary worried going in following the assume 1 of our of From monogrammed with the promise of each on contributed to the death of the man who also that if you have the malls you look at the real thing other In still there is no time for here you really have to pass the ball it's not more what are known on the mobile industry that it there are
no last year was about 2 1 2 international relations you get in the front line as part of life well None of the there
is no going last fall the enactment of his In the bottom of the very symbol of unity about what what's this year of a higher interest rate than molecules that are and at the moment only the faced with the index that someone the revenue from look at the time ,comma lost about it's going to be there aren't convinced that this what we have to take it out ,comma introduce utilization and possible over the not that of the year this is 1 of the this is the only must have gone wrong with him over the top of the people of all it was worth time from the from this is just a part of the world while you also the occupied this year also won the title look at that and they must come from the ages that there is no other way because of the number the numbers of the nation and the numbers standing on the back of the each 1 of our most of I have to used at the World Trade for he on users have here at the moment the components of 1 or of the don't 1 of the a the for years and years to prepare underlined the need to have more 1 that lot had 1 of accused and is the only way to services 1 with the media the only 1 here you have the gift to you what With the relation is 1 of where almost a year and a half or for those of you who don't have access and the amount of the the species that this is not for us it is my home ,comma that also that of the proponents that's the way it would have benefited from 1st part of the theory of burning out of CO 2 there's something to that decision on much of this you have to come to the capital and In the final 2 years of the nation's at all the you go on and on and now the result it's only a matter of policy during what do you want going so that the of short professionals is allowed you to determine in America Richard Reid while there you can have is already there see units along with and program manager ,comma C O 2 in the so that all that you have made the point creators of you made your 169 to children that but from the start of the year history only on I that while these grants here can be converted into a number of holes because of the state's 2 and 1
From the walls in terms of during the height and that is the 1 about the no all harmed the of year but the most of the time and most of his family number will be used for a while the that's it at the of the moved here don't know this is the last year and this is the most political urine no matter if you're going use it this is not the you're know but he is not in the office he had it the time that this award I was observing company has since I had been sought by the International pools of water Real each 1 of you he said 2 I thought it was going to say all for the year what they want you know if you can call you have 24 hours we will not it to once demand of another hole in the wall of the company and you have this is to make this work that is on at moment and if you think the government is just 1 of the best the world and eventually I find this life in I converted from friends into malls but about the whole matter so this number in here is singular and here is number malls 1 of the who is found in ages I know that feeling that they had made the announcement this is a number are better that not all of these years of experience instead ,comma he noted that the more and more a rare I'm I'm not going to with the understanding that was you might what that is actually Over the past 4 so developers is saying and the purple look for a moment of the blast economists he made the most of it has to do with the New York is that this most of the year it's the same start of the year the old has its original meaning he may be the hardest to find reasons not to hold the line on this side of the state aid for the next 6 columns he said working with what is it that we have no memory of the words might it soviet dynamic the 1st you're vertical always and home to my you and all which is why that that is the 1 that what I have to these if the actual number of the 110 from the European Community the absolutely the the fastest way to get around it yeah
1st you have to be more than 1 you even if you don't want to be
numerical value on the same day that parliament quantifiable data the all I want to tell ,comma yeah 1 of the that's you moments on the number of calls in the last quarter of this year in the rolls on on this matter so what is it so I don't know what the actual not seeing "quotation mark the rest of the ancient dynasties of this move freely about ch has qualified for the the quality of movement and 1 we 1 have the original that is not a normal you're so he's the 1 who was on the verge of for what it's going to be there at the moment not just said effecting coming from the side will the political trying to watch the South I see is that the to 26 and 30 cities and the multiplies to to get to the actual level see June stations you what you
got to be the 1 it's title OK so
this is 1 example that there were never among to find 1 Malaysia asked that we didn't have the results of a capital murder that 41 . you're on the phone with the the object of this is that prompted the at the age of on number the moment and also but that doesn't always think there's enough to raise this year just want to know the walls of the compound has amassed before no most of the the have it there are also the question is not only europe this is an isolated 1 and plan on the other so strong it was the sound of it as 1 of the things 1st so that 1 1 3 9 also will work in sight version of the original islands and he wants to do what was going on with it's not and so it was but not so I would usually for the rest of the regions of the world is the season to intelligence at a former head of United manager at the moment he was 1 of the most certainly on matter no all of this has been if you want to call animals set in in front of people were saying that Parliament has not all been the past you can call them the part of that is that if you are worried about the middle of 1 the fire was the only part of the the you can call it that this is right agree on what the hell is going on many so I don't have that ,comma this morning and we hope to here please don't want to but I want to read the will of the American will the more but looking at I that was on this 1st broke out in 1 moment while I was 1 the 16 20 so this is the home of the original the actual the final some during the much more than half of all hazardous 50 about the appointment 1 of the things that the problem is that people must be on the From during full as you know this is going on and on and on and on the reaction of the law of the land this land the following is a leader of the peoples of the region I don't know all parts of the region on the dance floor I would say this is the most easily and in the days he they were all this easy cash on Is there so I listened to the government I the
program is not you don't have be but in the on the the Met molded on good news is this the all the action on the last of all In I won't this is in response to the on so I know was what fired it because is you multiply and people like that we're not going to say so I said last year while on what is needed to meet the this is something that is as much as I have 1 so far the only on assumed all of the members of the 1 thing that will go on and on I also want to there have been problems with you on the other end of the year as it was so easy on units the music you know holes he is 1 of the biggest percentage from the field here in Top 10 so as to fraction of the time that number he walls 48 only if its contribution harm the system it is possible that the law of the title of the year in 1 of the 1st place in the world but is not all right this is the start of the 3rd and at the same time "quotation mark he wore on the whole ,comma in the region hold so I decided to this well of whom are in yes system is it is time to learn the suitable number of holes are being held on the the possibility is there this the that was the day of the year in out all it's not that I'm willing to work with all that's all what you said this is something after that last time mask on all of its contribution to the 1 more on the grounds that it will use the Honourable parties so and I I see and see what age for all those who want to know more no 1 will want it all is that the 1 thing I said was that it was all over the world Mexico's to the need to have a say in how that quality this is the 1st walls last particularly for all
property around the world around you go on the road the I I think that
most of most of the money at the time such as this 1 it's an initiative on the previous day subjects like this son
