news. jacob zuma has resigned as president of south africa with immediate effect. he made the announcement in a televised address a short while ago, bringing to an end his turbulent nine years in power. mr zuma, who's faced persistent allegations of corruption, said he disagreed with the way the ruling party, the anc, had demanded his resignation. he'll be formally succeeded by cyril ramaphosa, the new leader of the anc tomorrow. our africa editor, fergal keane, has the latest. the moment of decision came late when he recognised he could not win. presidentjacob when he recognised he could not win. president jacob zuma addressed when he recognised he could not win. presidentjacob zuma addressed the south african nation and face reality. i was just yards from him when he said those words. the anc should never be divided in my name.

i have therefore come to the decision to resign as president of the republic with immediate effect. and, with that statement, jacob zuma has brought to an end the most controversial period in the history of post— apartheid south africa. history, happening in the late at night. after a day in which it seemed he might still fight on. in pretoria, the seat of the presidency, rumours of an imminent resignation had rippled all afternoon. yet when he made his first appearance of the day on state television, he was defiant and defensive. zuma the victim. what have i done i have explained many times that this process... there is nothing i have done wrong. this is politics. it is a new phenomenon. what is the problem? at the same

time, in cape town, anc mps were meeting to decide whether they would support a motion of nonconfidence to drive him from power. the decision came quickly and was decisive. we are fiow came quickly and was decisive. we are now proceeding with, as the chief whip, to proceed with a motion of nonconfidence tomorrow so that president zuma is removed so that we can proceed to a lack president —— ramopoza. —— elect. can proceed to a lack president —— ramopoza. -- elect. he became party leader in 2009. even though he already faced serious corruption charges. i interviewed him just as he was about to become state president. many people think you are ci’oc. president. many people think you are croc. is that so? i want to see those people so they can tell me why. —— crook. those people so they can tell me

why. -- crook. are you a crook? i don't know. i have to read in a dictionary what that is. it is because of his relationship to the guptas family which forced the anc to act. they said they used their relationship to acquire assets worth millions of pounds. so powerful, it is alleged, they could hire and fire cabinet ministers. today, they also felt the pressure to be this was a police raid on their compound in johannesburg. —— pressure. seemingly untouchable until now, criminal charges could be imminent. if you wa nted charges could be imminent. if you wanted proof of the change in political temperature, this is it. the police cnet last to have found their courage. —— seen at last. by their courage. —— seen at last. by the end of this dramatic day, jacob zuma seemed friendless, politically isolated, resigning before he could be the mediated in parliament. fergal keane, bbc news, pretoria.

and we will discuss this with a former anc mp. good evening. you tweeted after the resignation viva, thank god. now to be charged and appear in court. will he be prosecuted? i think it is very likely. i was contacted a few months ago by the national prosecuting authority asking whether i would be willing to give evidence against president zuma having investigated his initial scandals involving a very controversial and corrupt arms deal. and i believe that the prosecuting authorities had contacted prosecuting authorities had co nta cted a prosecuting authorities had contacted a number of other people, all of whom, like myself, indicated they would give evidence. so, my sanchon is they were probably preparing the way in the event given a victory of the opposition. —— my

presumption. now that his position as won and president zuma resigned, i would not be surprised if charges we re i would not be surprised if charges were imminent against former president zuma. in the scheme of things, what has the presidency meant for south africa 7 things, what has the presidency meant for south africa? with nelson mandela, there were so many dreams, so mandela, there were so many dreams, so many great hopes for this nation. what has gone wrong in your opinion and zuma? -- under. the key to understand the alleged looting of the state by president zuma is the fusion of the anc as a party and the state. president zuma deployed people loyal to him and him only into key positions throughout government, the supposedly independent constitutions of the state. to further his own material

accumulation and to make sure he would not be prosecuted. i think that has been the tragedy of the zuma years, the extent to which the state has atrophied, the extent to which zuma was able to engage in such widespread looting of south africa. and the fact that so many, including many anc parliamentarians and anc officials, they have enabled this corruption to take place. but also, at the same time, ben, it is a remarkable testament to south africa's democracy, especially to the independence of the judiciary and incredibly vibra nt the independence of the judiciary and incredibly vibrant and tough media that has actually brought jacob zuma, finally, to account today. very good to talk to you. thank you for your time. andrew

feinstein, former anc mp. morgan tsvangarai, zimbabwe's main opposition leader, has died. the 65—year—old, a former mine worker, had been suffering from cancer. mr tsvangarai's career was marked by a long political struggle against the former president, robert mugabe, and he was beaten and imprisoned many times. the movement for democratic change that he set up in 2000 said tonight that they had lost an "icon and fighter for democracy." 15 people have died and more than a dozen people have been wounded in a shooting at a school in florida. an 18—year—old boy is thought to be the gunman and is in custody after surrendering himself to the police. it happened at the marjory stoneman douglas high school in the town of parkland about 45 miles north of miami. the democratic unionist party says there's no prospect of a deal to restore northern ireland's devolved government despite the intensive negotiations of recent days. the dup leader, arlene foster,

said that one of the main stumbling blocks was sinn fein's desire for an irish language act. our ireland correspondent, chris page, has the latest from stormont. a breakthrough seemed likely when theresa may visited northern ireland on monday. she and the irish prime minister said they were hopeful of a deal between the parties at stormont. now, the prospect of renewed power—sharing is disappearing. unionists have accused republicans of asking for too much. we have, as i've said before, run out of road in respect of this process. we're not going to be able to get the executive up and running because there is not a fair and balanced package available. but sinn fein say the dup are to blame for the collapse of the talks. there was a lot of expectation over the course of the last number of days where people were either briefed or were discussing the fact that there potentially was a deal on the table. i'm saying confidently that we had an accommodation with the dup and the dup leadership have failed to close on that accommodation.

action! the most difficult disagreement to resolve has been over the irish language. nationalists want a new law to protect and promote it. unionists want a wider piece of legislation including cultural elements which are more important to them. valentine's day brought a demonstration at stormont about another sticking point in the talks, sinn fein want to legalise same—sex marriage in northern ireland. the dup don't. there have been no ministers in place here for more than a year now. that means civil servants have, in effect, been running northern ireland, but they don't have the power to make any major decisions. the westminster government acknowledges the uncertainty is affecting public services and can can't continue. we need to consider practical steps. in the continued absence of an executive, other challenging decisions will have to be taken by the uk government.

the dup have said ministers should be appointed in london to take on stormont‘s powers. a fix for the broken politics of this part of the uk feels a lot further away tonight. chris page, bbc news, belfast. borisjohnson has urged his fellow brexiters not to gloat about the uk's departure from the eu and he's appealed for people to unite behind the vision of an outward—looking, confident uk outside the european union. mrjohnson also insisted the referendum result could not be reversed and he questioned the economic benefits of staying in the single market and customs union. vicki young reports. we're on the road to brexit. but cabinet ministers are still arguing about which route to take. do we stay close to the european union and all its rules, or take off in a completely different direction? many are anxious about the journey ahead. including liberal democrats, who laid on this less—than—friendly welcome for the foreign secretary. he's trying to reach out to soothe concerns and convince them that brexit is grounds for much

more hope than fear. it's not good enough for us now to say to remainers "you lost, get over it." because we must accept the vast majority are actuated by entirely noble sentiments. brexit is not about shutting britain off, he said, it's about going global. i absolutely refuse to accept the suggestion that it is some un—british spasm of bad manners. it's not some great v sign from the cliffs of dover. it is the expression of a legitimate and natural desire for self—government of the people, by the people, for the people. at times, this speech felt like a return to the heat of the referendum debate. and mrjohnson certainly has not changed his mind about the need to diverge from eu rules. the british people should not have new eu laws affecting their everyday lives imposed from abroad when they have no power to elect or remove those who make those laws. that would be intolerable, it would be undemocratic, and it would make it all but impossible for us

to do serious free trade deals. he did say he was happy for them to remain subject to eu law for a transition period which could start for march in 2019 and could last two yea rs. as the face of the leave campaign, some question whether borisjohnson is really the right person to try to heal the divisions of brexit. but he acknowledges today that that positive case for leaving the eu still needs to be made and says that he has to try to make it. but what about the obstacles that could lie ahead? boris is really good at the broad brush strokes. but i think what is really needed now are the details. you know, we'rejust over 1a months away from the uk leaving the european union. and details on things like customs and borders, how the really difficult of the irish border is going to be delivered, how eu citizens will be able to stay here, the position that they will be in,

all that is needed now. we have had the referendum and we are not going to have a second one and we will not be part of the single market for the customs union, we are taking back control copy that is what the speeches about. -- that is what the speeches about. -- that is what the speeches about. -- that is what the speech is about. more flesh on the bones is what critics want. downing street insists they will get that in the coming days when the spotlight turns to theresa may and what is billed as a significant speech on security. vicki young, bbc news, westminster. and that is a summary of the latest bbc news. newsday is coming up at midnight. now on bbc news, it's time for newsnight. the usual form is that the northern irish parties have the occasional lengthy sulk but then make up and get on with running the country again. this time it's just the sulk. the position of the uk government remains the same, devolved government is in the best interest of everyone in northern ireland, and is best for the union. for the northern ireland secretary,

it's a valentine's day headache. we'll ask the dup whether they are embarrassed at the inability of their region to look after itself. oxfam loses another star. senegalese musician baaba maal told us tonight he's withdrawing as an ambassador for the charity. the charity's former nigeria country manager tells us her own experiences of working there. and i thought that i would be protected. i thought i would be safeguarded from sexual harassment and from sexual abuse. and why don't women dominate in subjects like science and maths? is it because they're just not interested ? people have long thought that the more gender equal a country, the more similar men and women will become in their interests and occupational choices. we find the opposite. we'll hear both sides of the argument.
