welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is lewis vaughanjones. our top stories: robert mugabe defies his own party and refuses to resign as president of zimbabwe. in a speech to the nation, mr mugabe says he will lead next month's party congress, despite mounting calls for him to stand down. talks to form a coalition government in germany collapse, threatening angela merkel‘s position as chancellor. the us navy sends special tracking equipment to help in the hunt for an argentine submarine. and portugal's worst drought in decades affects thousands of honeybees, damaging honey production across the country. robert mugabe remains president of zimbabwe,

despite a tumultuous weekend that saw popular protests against him and an ultimatum from his own party. a live address to the nation, widely expected to include his resignation, saw him pledge instead to oversee his party congress next month. but the party has already replaced him, and given him until midday on monday to resign orface impeachment. here is our africa editor fergal keane. the very music seemed designed to drain any drama out of the moment. and perhaps the geniality of the encounter was a giveaway. robert mugabe did not look like a man about to walk into the wilderness. and his words, delivered 15 minutes into a rambling address, confirmed that he intended to stay as leader of the country and party, at least until the party congress in december. the congress is due

in a few weeks from now. i'll preside over its processes, which must not be repossessed by any acts calculated to undermine it, or to compromise the outcomes in the eyes of the public. he praised the military, and acknowledged the crisis in his country and party. the way forward thus cannot be based on swapping vying cliques, that ride roughshod over party rules and procedures. there has to be a net return to the guiding principles of our party, as enshrined in its constitution.

this appearance has shocked zimbabweans, who were prepared to witness his resignation. i think we're being played. i feel let down. by now we should have produced some sort of result, but it's like we are back to square one. what did you make of that? you were expecting him to resign. i think the whole nation was expecting him to resign. and we're all shocked. i think people will be depressed, confused. people do not understand what's happening. but i think we're in a post—mugabe era. it will happen. there are big questions now, how can robert mugabe preside over a party which today removed him from the leadership? once—loyal supporters met to warn

that he would be impeached by parliament if he did not step down from the presidency by midday tomorrow. an old friend read out the sentence. tonight's non—resignation doesn't change the feeling of the party, and it doesn't remove the bitterness against his wife, grace, and her friends. it has to be over now? oh, yes. it is over. what he did is enough. enough is enough. the people of zimbabwe have shown, in numbers, that they are fed up with this dynasty, and a new era is beginning. look at my back. this is the moment when robert mugabe lost power in his own party, the party he dominated for so long, and has now been replaced as party leader by a man who was one of his closest allies for decades. the crocodile...

the new leader, emmerson mnangagwa, is known as ‘the crocodile,‘ celebrated here for his ruthless cunning. when he gets his prey... he may have agreed to pause, but he is unlikely to stop until he ousts his old comrades. on the streets of harare, the president's people seem to occupy a different nation. here praying for reconciliation and healing. they have already started to move beyond the trauma of the age of mugabe. horace campbell is a visiting professor at the university of ghana. when discussing president mugabe's speech, he said that changes to zimbabwe's constitution should not be decided by the ruling party. it's not a speech about zimbabwe. it was a speech about the party. and the party was part of the problem. so the questions of the future constitution of the government of zimbabwe will not be decided by the party. so the focus should

not be on the party. the focus should be on an inclusive government, and robert mugabe will be irrelevant. to that inclusive government. the people of zimbabwe, in their tens of thousands, showed that yesterday when they came out on the streets. but he didn't resign. how surprised were you by that? i'm not surprised by that, because robert mugabe has enough information on the general, on mnangagwa, on the head of the war veterans, that he's playing for time. the question is, can they call his bluff? can they cut off his telephone discussions with zuma ? can they ensure that he does not move any money around, that he may have in banks overseas, so that the articles of impeachment in the parliament can be prepared

for tuesday, so that the question of his being the head of government and head of state is resolved by the parliament of zimbabwe? do you think the protesters that we've seen out on the street will stand for it if he doesn't go, and go quickly? they will not stand for it. the protests on the streets represent the culmination of 10—15 years of struggle by the people of zimbabwe. and what is important about the speech night, that came from mugabe speaking about the political party zanu—pf, is that that speech did not include any discussion about the people of the streets. there must be an inclusive government, there must be

a transitional period, and the institutions in zimbabwe must be changed so that the authoritarian tendencies in the political party are taken out of the government's structure of zimbabwe. talks to form a coalition government in germany have collapsed. christian lindner, the leader of the liberal free democrats, said his party was pulling out because it had not been possible to find a basis of trust with chancellor angela merkel‘s christian democrats. mrs merkel said she would now meet the german president, who has the power to call a new election. andrew plant reports. after three terms in office, angela merkel‘s hopes of staying in power rest on forming a coalition. an election in september left mrs merkel without a majority, with some voters angered by germany's liberal policy towards refugees. translation: the fact is that we could not finish the exploratory talks successfully. that means that i will contact the federal president tomorrow, inform him about the state of affairs, and then we will have to see how things develop.

to form a stable government, she needed to reach agreement with the free democrats and the greens. it would span from left to right on germany's political spectrum. but finding common ground has proved impossible. the leader of the free democrats saying the parties had no common vision for the country. translation: we will not abandon our voters for a policy with which we are not convinced. it is better not to govern than to govern badly. there are ways forward. negotiations could continue, if angela merkel can persuade the free democrats back to the table. without them, she could only form a minority coalition, something commentators say is highly unlikely, which leaves the possibility of calling another general election. what is certain is the failure to form a coalition means angela merkel‘s position suddenly more uncertain,

after 12 years at the top of european politics. andrew plant, bbc news. five countries are involved in a huge air and sea search for a missing argentine submarine. contact was lost five days ago, as the sanjuan returned from a routine mission off the south american coast, with 44 crew on board. signals have been detected which may provide clues to its location. dan johnson reports. this is a vessel designed to play hide—and—seek in the deepest depths. so finding the sanjuan, its crew, and the 22 torpedoes it carries is a real challenge. fresh satellite signals, albeit weak ones, have revived hopes of rescue. seven call attempts have been received, says the navy‘s spokesman, but they were incomplete, and need to be checked to pinpoint the location. he stressed they're making every effort to find the submarine, searching the open ocean and the sea bed.

this is now an international effort. the us navy has flown in deep—sea rescue equipment. and hms protector, the royal navy's antarctic patrol ship, has been diverted to help scan beneath the waves of the south atlantic ocean. the sanjuan left the southern port of ushuaia last monday, after a routine mission. it was making the 2,000—mile journey back to its base in mar del plata, not far from argentina's capital. the search is focused around halfway, in the sanjorge gulf, where the submarine last made contact on wednesday. one of the 44 crew members is argentina's first female submariner. the best hope of finding her and her crewmates alive is that a power failure knocked out the submarine‘s communications. six countries are now hunting for the san juan, but it is lost in a huge area of ocean, and bad weather is making a difficultjob even harder.

dan johnson, bbc news. candace piette is the bbc‘s regional editor for latin america. i asked her how significant the satellite transmissions were in the search for the submarine. well, they were initially considered to be very significant. they were very weak, to all these naval bases along the coast of argentina. and they provided a great hope, particularly for relatives of the crew. but, in the last 2a hours, the argentine navy has said that the company that's been looking at the signals and trying to work out exactly where they were coming from says they didn't come from their equipment aboard the sanjuan. but they didn't dismiss that it could be coming from other satellite equipment. so that's one part of the puzzle sorted, then. we're now in a situation

where they're still looking for this boat. possibly the satellite signals are coming from an emergency buoy that the sub might have ejected at some point. it's a potentially huge search area. how crucial is the international search effort? they're looking across a section of sea of around 400 kilometres squared, just off the valdez peninsula in the south atlantic. the international effort is been very important to the argentines. the navy all along has been saying that they welcome all the help that particularly the us, with its high—tech aeroplanes and detecting equipment, and its deap—sea rescue modules that it's just brought in in the last 2a hours. the uk also has a couple of sophisticated communications

boats and a hercules plane. so there's four countries that are involved. they're sweeping the sea, they've been doing that. and the trouble has been very difficult weather, and making it very hard for the sonar equipment on board these boats to actually detect anything. they're getting false messages coming back, bouncing off these very high, seven—metre waves. stay with us on bbc news. still to come: we take a look at singapore's display of impressionist art, asian—style. benazir bhutto has claimed victory in pakistan's general election, and she has asked pakistan's president to name her as prime minister. jackson has been released on bail of $3 million, after turning himself in to police in santa barbara. it was the biggest demonstration so far of the fast—growing european anti—nuclear movement.

the south african government has announced that it's opening the country's remaining whites—only beaches to people of all races. this will lead to a black—majority government in this country, and the destruction of the white civilisation. part of the centuries—old windsor castle, one of the queen's residences, has been consumed by fire for much of the day. 150 firemen have been battling the blaze, which has caused millions of pounds‘ worth of damage. this is bbc news. the latest headlines: robert mugabe has defied intense pressure to resign as president of zimbabwe, prompting an angry response from many of his former allies. let's stay with that story.

thousands of people took to the streets of harare at the weekend in support of the army's actions against president mugabe. shingai nyoka has been speaking to residents in the capital to get their reaction to mr mugabe's refusal to resign. we must learn to forgive... they came to listen to what president mugabe had to say. after a meeting with army generals responsible for a takeover earlier last week, they had expected to hear his resignation speech. at this bar, they waited and waited to be told by president mugabe in a stumbling address... all this now has to stop... ..that he was going nowhere. he does not speak for our interests. he only speaks for his personal interests, and his family. so, why are you so disappointed? we are suffering! we are suffering. we have had enough of suffering. we need him — we need him to change his mind. we need him to resign. he didn't actually say he's

resigning or anything, so we're still waiting. the people marched yesterday. they expressed their views. i'm a young lawyer in zimbabwe. i've been practicing law for the past three years. it's pathetic. the country has gone to the dogs. the consummate politician appears, at least for the moment, and on the surface, to have negotiated a deal on his own terms. this is not the announcement that some zimbabweans were waiting for. robert mugabe is still the president and it's not clear whether parliament will now begin its impeachment process. people here today were expecting to hear the resignation they have demanded, but those hopes have been dashed. the wild celebrations we have seen on the streets stand in stark contrast to the sombre mood in harare tonight. let's take a look at some of the other stories

making the news. 15 people — including several women — have died in a stampede at a market in morocco where they'd gathered for a handout of food aid. it happened in the town of sidi boulaalam, near the coastal tourist resort of essaouira. it's not clear what triggered the stampede. morocco's agricultural output has suffered from a drought, which has pushed up food prices. turkey's capital has banned all gay festivals, forums and exhibitions. ankara defended the move, saying homosexual events are not conducive to public order, given turkish "sensitivities". turkish authorities banned a german lgbt film festival in the capital last week out of fear it could be ‘provocative‘. more than 30,000 runners have taken part in delhi's half marathon, despite calls by doctors to postpone it on health grounds. air pollution was measured at eight times above safe levels. some runners wore anti—pollution masks as they took part. months of high temperatures

and virtually no rain has caused the worst drought this century for spain and portugal. more than 80% of portugal is officially classified as enduring "severe" or "extreme" drought. now there are concerns for the country's population of bees — which are crucial to pollinating crops. georgina smyth reports. beekeeping is serious business. luis correia's 600 hives should be bringing it eight tons of honey each year. but portugal has suffered its driest weather for more than 20 years. so bad in fact it meant far fewer flowers and so less food for the bees, causing the honey yields here to crash to a quarter, just two tons this year. translation: it was a bad year because we had a very dry spring, a very hot summer.

for three months, the bees could not collect any nectar. it's been a year of hunger and very weak for bee keepers. the lack of food means beekeepers have to buy in pollen substitutes. he needed a whole ton just to keep his hives alive. it's the same story across the country. translation: spring this year didn't have humidity to give plants enough nectar for bees to produce honey. after prolonged drought, late spring and forest fires, production decreased 80%. the honeybee population worldwide has been in a serious decline due to pesticides, parasites, changing climates and loss of habitats. in portugal, every part of the agricultural industry has been affected but for beekeepers, the driest weather for two decades has pushed their colonies close to collapse. in greece, emergency teams are continuing their search for those missing following flash

floods caused by days of heavy rain. on saturday, the bodies of three people were found, taking the total number of dead to 19. flooding struck early on wednesday in the towns of mandra, nea peramos and megara, some 50 kilometres west of athens. david campa nale reports. witnesses described this week's raging floods as like a tsunami. the force of the rainwater moved vehicles, damaged walls and swept away those caught in the open. the sudden torrent of water also rose inside buildings to lethal levels. to escape, residents took desperate measures, spending the night on their roofs. the victims include elderly people trapped inside their homes, unable to escape. translation: from what you can see here, there is total destruction. nothing is standing. we are trying to pick up our fragments and pieces. they tell us to show courage but we also need help. courage is not enough. crumpled cars and mangled furniture remain on roads coated in the thick mud. the local authorities are attempting to clear out the devastation but face further rainfall. even the local cemetery was submerged in mud with tombstones broken and strewn about.

experts say ill—judged building in the area, some of it by local council authorities, prevented water from running off. this week's floods were a disaster waiting to happen. a new exhibition has opened at singapore's national gallery that focuses on artists of the 19th century, from two separate — but overlapping — parts of the world. called ‘century of light‘, the show features many impressionist classics on loan from paris, alongside works by two of asia‘s most successful painters. mat morrison went to take a look. western—style, european faces, but by an asian hand. these are some of the works ofjuan luna of the philippines and raden saleh of indonesia, now on display at singapore‘s national gallery. both of them were trained in their respective countries, indonesia and the philippines, before travelling to europe. juan luna won major awards in spain.

and this was the first time an artist from the colonies achieved the same status as their european peers. luna‘s work, espana y filipinas, or spain and the philippines, puts their colonial relationship in a greco—roman motif, with spain leading the way up a grand staircase, to the future. raden saleh of indonesia was known for his orientalist animal hunts and landscapes, winning over an audience eager for such exotic scenes. even as their asian contemporaries enjoyed a degree of success in europe, some impressionist painters had trouble finding an audience at home. this painting by claude monet was actually rejected by the paris salon of 1869. but today, impressionist works are as popular as ever, especially here in asia. you can see it in the japanese bridge. we are where monet built this garden. paul perrin is a curator at the musee d‘orsay in paris. he helped bring about 60 paintings to this dual exhibit, a greatest hits album of impressionist masterpieces.

you don‘t need to have a very important knowledge of classical european culture. you don‘t need to know a religious subject, or mythological subjects, or history. just nature, just people. this is something that can connect with some some part of the asian philosophy. taken together, the two exhibitions represent an east—meets—west—meets—east again moment in art. and then of course, some things are universal. how many selfies do you think people are going to take? they are doing a lot of selfies. now, if you like flying at up to 500 kilometres an hour — and just a few metres from the ground — this race in thailand may interest you. the air race—one world title sees up to eight pilots speeding along an oval circuit.

their light planes must complete eight laps, atjust above tree top level. this year, american tim cone won the title in a late surge in a grove—winged cassutt racer, named ‘what aeroplane honey‘. hello. it‘s safe to say there is a lot of weather to come in the week ahead. low pressure after low pressure will be coming in from the atlantic. this is how we are starting the week. still cold enough for a bit of snow into the scottish hills for monday morning. but milder air will be pushing in across much of the uk for a time this week, because it looks like this will be pushed away by colder air, again from the north, by the end of the week. but this is how we start off on monday — some snow on the hills in northern scotland, so some slushy roads

for higher—level routes here. a lot of rain elsewhere in scotland to begin with, and a lot of cloud across the uk. still chilly, then, in northern scotland. we‘ll see the rain and the snow tending to fizzle out as we go through the morning in scotland, and some outbreaks of rain to begin with for northern ireland and northern england. come further south, yes, there‘s plenty of cloud. there isn‘t a huge amount of rain. damp and drizzly in places but what we will notice the most is how mild it is compared with recent mornings. starting the day across much of wales, the midlands, south—west england, the temperatures into double figures. so the milder air moving in, but it‘s doing so with plenty of cloud. so we‘re hard—pressed to find much in the way of sunshine at all on monday. just a few brighter breaks to the east of high ground. outbreaks of rain fizzling out, but there will be patchy, mostly light rain still around into the afternoon in some spots. double—figure temperatures maybe even into southernmost parts of scotland, but elsewhere in scotland, still single figures for another day. so still a chilly feel, especially the further north you are. on through monday night and into tuesday morning, we‘ll take another spell of rain

through northern england, through northern ireland, and into scotland. but any snow on the hills turning back to rain as we turn ten things milder here eventually, as we go on into tuesday. a very mild night elsewhere, but again with plenty of cloud. it looks pretty wet on tuesday, especially in northern scotland. though to the east of it, before any of it gets in, given any brighter breaks, again temperatures very mild, and a few spots reaching into the mid teens for a while midweek in the uk, with stronger winds for a time. you can see low pressure systems are queueing up some wetter, windier weather for a time mid—week, but we are expecting things to turn cold again by the end of the week. so the milderfeel may just be brief. rain at times, and a bit of snow, especially on the hills in scotland. often windy at times this week, as well, and a colder wind by the end of the week. this is bbc news.

the headlines: the zimbabwean president, robert mugabe, has defied widespread demands that he step down. in a highly—anticipated speech to the nation, mr mugabe announced his intention to lead next month‘s ruling zanu—pf party congress. the party has given him until midday on monday to resign orface impeachment. talks to form a coalition government in germany have collapsed throwing chancellor angela merkel‘s future into doubt. the leader of the liberal free democrats said his party was pulling out because it had not been possible to find a basis of trust with chancellor merkel‘s christian democrats. us planes carrying underwater rescue equipment have arrived in argentina to help hunt for a missing argentine submarine. the sanjuan disappeared four days ago in the south atlantic with 44 crew on board. britain, chile and brazil have also joined the rescue effort. now on bbc news,
