BERNIE SANDERS CEMENTS FRONT-RUNNER STATUS WITH NEVADA CAUCUSES WINBernie Sanders has cemented his status as the Democratic front-runner totake on Donald Trump in November's US presidential election.He is projected to win Nevada's caucuses, and early results suggest he is oncourse for a large victory.There is a long way to go, however, until a nominee is confirmed.Early results also suggest former vice-president Joe Biden has performedbetter in Nevada than in the other two states which have voted so far.He had underwhelming results in Iowa and New Hampshire. Those states kickedoff the four-month long primaries process, in which candidates are jostlingto convince voters why they are the best candidate to challenge Mr Trump.So far, with 11% of the ballots counted in Nevada, Mr Sanders, the left-wingsenator for Vermont, has 47% of the vote, ahead of Mr Biden on 24%. Thefield is then split between a number of other moderates, including ElizabethWarren and Pete Buttigieg, who trail further behind.Candidates who have won more than 15% of the vote will be awarded delegates,who will then go to the party's convention in July to support theirDemocratic candidate.Before Saturday, Mr Sanders had 21 delegates, and while he will remain along way off the 1,990 needed to become the nominee, victory in Nevada willbring him another small step closer towards that total.LET'S GET TOGETHER TO TAX TECH GIANTS: G20 OFFICIALSLeading world economies must show unity in dealing with aggressive "taxoptimisation" by global digital giants like Google, Amazon and Facebook, G20officials said on Saturday.Global rules are being developed by the Organisation for EconomicCooperation and Development (OECD) to make digital companies pay tax wherethey do business, rather than where they register subsidiaries. The OECDsays this could boost national tax revenues by a total of $100 billion ayear.The call for unity appeared mainly directed at the United States, home tothe biggest tech companies, in an attempt to head off any stalling on therules until after the American presidential election in November. "There isno time to wait for elections," German Finance Minister Olaf Scholz told atax seminar on the sidelines of a meeting of G20 finance ministers andcentral bankers. "This needs leadership in certain countries," Scholz saidlooking directly at US Treasury Secretary Steven Mnuchin, sitting next tohim at the seminar. The taxing of digital firms and the effect of thecoronavirus outbreak on the global economy are among the hot topics for G20financial leaders, from the world's 20 largest economies, during their talksin Riyadh this weekend. The OECD wants to set a minimum effective level atwhich such companies would be taxed and seeks agreement by the start ofJuly, with an endorsement by the G20 by the end of the year. "A coordinatedanswer is not the better way forward, but, given the alternatives, the onlyway forward," OECD head Angel Gurria told the seminar.
