Hello and welcome to today’s live global coverage of the coronavirus pandemic with me, Helen Sullivan. As always, please do get in touch on Twitter @helenrsullivan or via email: helen.sullivan[at]theguardian.com. Comments, tips, news from your part of the world are all much appreciated. The Spanish government declared 10 days of mourning starting on Wednesday for the nearly 27,000 people who have died from coronavirus the country. It will be the longest official mourning period in Spain’s four-decade-old democracy. Flags will be hoisted to half-staff in more than 14,000 public buildings and on Spanish naval vessels until 5 June and King Felipe VI, as Spain’s head of state, will preside over a solemn memorial ceremony. Meanwhile, known deaths worldwide are nearing 350,000, with 349,894 currently confirmed, according to Johns Hopkins University data. The US alone accounts for under a third of these, with 98,852. But the true US death toll will probably have passed the sombre milestone of 100,000 days before the official tallies reflect it. Here are the latest developments from around the world: Known deaths worldwide near 350,000. According to the Johns Hopkins University coronavirus tracker, known infections worldwide number at least 5,584,091. The known death toll stands at 349,894. True death tolls and cases are likely to be significantly higher due to differing definitions and testing rates, delays and suspected underreporting. Tory unrest increases pressure on PM to sack Dominic Cummings. There is growing revolt within Boris Johnson’s party over his refusal to fire Dominic Cummings, his chief adviser, over his lockdown breach. A a junior minister has resigned, and 30 other Conservative MPs have called for Cummings to go. Eight more Tory MPs were publicly critical of Cummings’ actions and three said privately that he should be forced out, according to the Guardian’s Heather Stewart, Rowena Mason and Kate Proctor. Twitter added a fact-check warning to the bottom of a tweet by US President Donald Trump for the first time. Trump tweeted: “There is NO WAY (ZERO!) that Mail-In Ballots will be anything less than substantially fraudulent. Mail boxes will be robbed, ballots will be forged & even illegally printed out & fraudulently signed. The Governor of California is sending Ballots to millions of people, anyone.....” Bellow the tweet there is now a link with the warning text “Get the facts about mail-in ballots”. On Sunday Trump suggested that supporters of mail-in voting were using the coronavirus outbreak to perpetrate a “scam”. Trump said he thought it was “very unusual” that Joe Biden wore a face mask yesterday while attending a Memorial Day ceremony. The president has resisted wearing a mask in public, even though the Centers for Disease Control and Prevention recommends that Americans cover their faces while out in public and around other people. The Pentagon’s deputy inspector general resigned. Recently, the president effectively removed Glenn Fine from his role leading a coronavirus relief spending oversight committee, and the defence department official has now become the latest inspector general to step down in recent weeks. The trading floor of the New York Stock Exchange was reopened after two months. Cuomo rang the opening bell to cheers from traders, who will still have to wear masks and stay six feet apart from each other when they’re on the floor. The WHO says the Americas are the new epicentre of the disease. The World Health Organization’s regional director Dr Carissa Etienne said outbreaks were accelerating in countries such as Brazil, where the number of deaths reported in the last week was the highest in the world for a seven-day period since the coronavirus pandemic began. The number of coronavirus infections to accelerate in Guatemala, El Salvador and Nicaragua, she said. The UN refugee agency said Covid-19 had pushed its humanitarian work to near “breaking point” in Yemen, a country devastated by five years of war. It said a growing number of families were resorting to begging, child labour and marrying of children to survive. A separate UN agency said it had only received around 15% of the funding required for the $3.38bn (€3bn) aid package for Yemen this year. Spain has declared 10 days of mourning starting on Wednesday for the nearly 27,000 people who have died from coronavirus in the country. Flags will be hoisted to half-staff in more than 14,000 public buildings across the country and on Spanish naval vessels until 5 June. It marks the longest official mourning period in Spain’s four-decade-old democracy. The UK death toll passed 47,000, according to new figures from the country’s Office for National Statistics. This figure is higher than the latest figure given by the UK government – nearly 37,000 – because it includes deaths in which Covid-19 is given as a “suspected” cause. The UK government figure only includes deaths of patients who have tested positive for the coronavirus. Russia reports record one-day rise in deaths. Russia has announced that 174 people with coronavirus have died in the past 24 hours, a record one-day amount that has pushed the nationwide death toll to 3,807. Officials reported 8,915 new cases, pushing its overall case tally to 362,342 – but Vladimir Putin said the country has “passed the peak” of the virus. Mexico City records thousands more deaths than usual, amid doubt over the official Covid-19 toll. This year, Mexico City has issued 8,072 more death certificates than the average for the same period in the past four years, according to a study that suggests the country’s coronavirus death toll could be significantly higher than the official figure of nearly 7,400. The report’s authors found 37% more death certificates were issued in April 2020 than that month’s average during the previous four years. By the end of May they estimated the number may grow to 120%.
