it comes ahead of an announcement next sunday which will set out its next steps. over 76,000 tests were carried out in the uk yesterday — a sigificant dip after hitting the target of 100,000 a day by the end of april. the phone app which will track and trace people with covid—19 will be piloted on the isle of wight this week. russia reports a record one—day rise in coronavirus infections, with more than 10,000 people testing positive. the us secretary of state says there is "enormous evidence" that the coronavirus pandemic originated in a chinese lab in the city of wuhan. now on bbc news, our world. oil—rich venezuela has been in an ever—growing state of crisis since hugo chavez died in 2013, and global oil prices crashed.

last year, the world watched as millions of venezuelans poured across its borders, escaping a country whose economy and infrastructure are struggling to function. venezuela has the largest oil reserves in the world, and was once the richest country in latin america. but 20 years of a populous government, first led by hugo chavez and now nicolas maduro, has left the country in ruins. people took to the streets to protest. inflation in venezuela is now the highest in the world. the healthcare system has collapsed.

more than 30% of the population doesn't have enough food, and many people don't have regular access to fresh water or electricity. by the end of this year, it's expected that more than 6 million people will have left venezuela. around 20% of the entire population. for those left behind, what started as a crisis has become the new normal.

0lga martinez lives in the town of machiques in the north—west of venezuela. she runs a shop from the front room of her house. ten years ago, most venezuelans could afford to go to the supermarket and

buy what they needed for the week. today, an estimated third of all venezuelans don't have access to enough food. for many of 0lga's customers, it's a daily struggle. for those without cash, 0lga lets her customers barter with what they have.

to buy supplies for her shop, 0lga travels to the centre of machiques. in oil—rich venezuela, petrol used to be virtually free,

but today, the oil industry is in ruins and petrol is scarce.

machiques used to be the ranching capital of venezuela. but the farming industry was decimated when the government expropriated farms and turned them into state—run collectives. with food in short supply, 0lga now grows her own food in her garden.

she also grows medicinal remedies. when chavez was in power, he poured money into a universal healthcare system, funded with money from the oil industry. but when global oil prices fell, the money dried up and the healthcare system collapsed. today, basic medicines like paracetamol are almost impossible to find.

in the capital caracas, this woman is trying to find somewhere she can buy her medication. the state of venezuela's healthcare system is driving people like this woman to seek alternative treatments. for the past few months, she's been seeing a spiritual healer.

the healer she sees lives in petare,

the biggest slum in caracas. she follows a uniquely venezuelan religion that claims to heal people by channelling the spirits of the dead. many hospitals lack even the most basic provisions, such as running water and cleaning supplies. half of all operating theatres have

closed and thousands of doctors have migrated. if patients do decide to have an operation, they have to buy the surgical equipment the doctors need. in the absence of a functioning healthcare system, seeing a spiritual healer is a last resort for people desperate for any kind of relief. today is deisy‘s third appointment with irian.

the fall in living standards in venezuela has forced around the 15% of the population to leave the country since 2015. deisy‘s husband and son are in chile.

they send her back a few dollars a month to help her survive. in maracaibo, venezuela's

second biggest city, life is returning to the streets. businessman ruben fernandez has decided to invest in the food industry. at the beginning of 2019, inflation in venezuela

was over 1,000,000%. with social unrest threatening the presidency of nicolas maduro, he decided to relax a long—standing ban on the trading of dollars. it allowed some businesses to get going again, easing pressure on maduro. now more than half the country's business is carried out in dollars. ruben has just invested in supermarket jeffrey's.

food here looks plentiful. that's because it's now possible to import and sell using dollars. for public workers like doctors and teachers who are paid in bolivars, $3 is equivalent for months pay, life is very different for those who can earn in dollars.

the growing diaspora is another major source. this year, it's estimated that $4 billion will be sent back by family members abroad. those with dollars can now shield themselves from some of the worst aspect of the crisis.

years of underinvestment in infrastructure have left the country suffering from chronic electrical blackouts. in 2019, venezuela's main hydro—electric power station failed and much of the country was left without electricity for over a week.

0lga had electricity

for most of her adult life. now her grandchildren have to do their homework by torchlight. as 0lga tries to adapt to her new situation, many fear the worst is yet to come. during the week—long blackouts in 2019, hospital generators failed. nurses had to pump ventilators by hand. young and old died. covid—19 has been detected in the country. without the medical resources to tackle it, it is feared venezuela

could become the epicentre of the outbreak in latin america. hello there. the weather will, of course, not be the main thing we remember about april 2020. but in normal circumstances, well, itjust might have been because it was an exceptional month, the sunniest april on record according to provisional statistics from the met office. also an exceptionally dry month.

where you see the dark brown colours on this map, that shows rainfall was well below average, particularly across parts of northern england and eastern scotland. so, will that dry trend continue as we move deeper into may? high pressure will try to keep things dry through this week but with low pressure squashing in from the south, see all of the white lines on the chart, the isobars squeezing together? that shows us that we're going to have an increasingly strong easterly wind during monday. that wind really picking up as we get into the afternoon. some showers across eastern england, particularly. many spots will be dry, best of the sunshine will be out west. temperatures typically between 1a and 19 degrees, but a little bit cool for some of those north sea coasts. the wind will strengthen through the evening, gusts of 45 mph or a touch more are possible for the far south—west of england. also turning very wet here and for channel islands as a frontal system slides its way in. but remember our area of high pressure? that will act like a block, it will stop this front making much progress northwards.

so, yes, we see rain across the south—west of england getting into parts of wales, the midlands, maybe the south—east during tuesday, but that rain tends to fizzle away as it runs into that are of high pressure. it's dry further north with some sunshine. highest temperatures at this stage, i think, across north—west england and western scotland. as we move out of tuesday and into wednesday, we keep a lot of dry weather, quite a chilly start on wednesday morning but then we see spells of sunshine. bit more of a breeze out west with some cloud and perhaps some showery rain coming and going at times. but those temperatures just nudging upwards, 19 or 20 degrees and certainly not feeling as chilly for those north sea coasts at the stage. as we move out of wednesday into thursday, our area of high pressure slips eastwards, low pressure squashing in from the west this time and that will drive something of a southerly flow across the british isles. so temperatures are going to start to rise, some warm air heading ourway. notice, though, something colder lying in wait up to the north. this is on thursday's forecast, a lot of dry weather around for many but across parts of norther england, northern ireland and scotland,

there's the potential for some pretty sharp showers into the afternoon, maybe with some thunder and some lightning. but those temperature 18 or 19 across parts of southern scotland, 22 down towards the south of england. as we go into friday, again there's the chance of some cloud and some showery rain across northern ireland, northern and western scotland. further east it is predominantly dry with some sunny spells, temperatures could well get up to 23 degrees. butjust signs of something chillier across the north of scotland. and as we go through next weekend, look at this, this plunge of cold air working southwards across all parts of the british isles. it will not feel much like spring at all, it's going to feel significantly colder. there is a chance of showers, some of those showers could even be wintry over the highest ground, some dry weather as well. then as we head beyond the weekend, so into the following week, high pressure still not too far away. it looks as if the high pressure might build a little more strongly towards the uk, cutting off some of the very coldest of that air and certainly bringing a fair amount of dry weather.

tonight at ten, easing the lockdown — ministers signal proposals ahead of an announcement next sunday. but there's a warning — restrictions could return in a "specific and localised way" if coronavirus cases go up again. the worst thing to do would be to prematurely relax the current measures to see a second spike which might risk overwhelming the nhs and which would compel us to introduce lockdown measures all over again. proposals include limiting passengers on buses and trains, and staggering times when people start work. and businesses are given draft guidance on how they can reopen safely once lockdown is relaxed. the phone app to track and trace people with covid—19 will be piloted this week on the isle of wight, and rolled out
