Oscars 2019: surprise wins for Green Book and Olivia Colman

The Oscars ceremony was notably diverse, and will be remembered for some historic wins – and the absence of a host – but Academy voters were accused of grossly overrating Green Book, which was named best picture in a surprise victory over Roma, and Bohemian Rhapsody, whose lead, Rami Malek, was named best actor.

A highlight of the night was Olivia Colman’s memorably hilarious acceptance speech after picking up the best actress award for The Favourite.

Terri Sewell, an Alabama congresswoman from the civil rights crucible of Selma, will introduce a bill to the House of Representatives tomorrow that could help repair American’s electoral system after it emerged that hundreds of thousands of people have been disenfranchised. She told the Guardian it was time to restore and advance American democracy, adding: “We don’t want just to shatter the glass ceiling, we want to break down the door.”

Disenfranchised. Last year’s midterm election cycle effectively disqualified voters from exercising their democratic right at rates “more widespread and brazen than in any other since the modern-day assault on voting began”.

The Venezuelan opposition leader is set to meet the US vice-president, Mike Pence, today after he called on the international community to consider “all options” to remove Nicolás Maduro from power. The meeting comes after at least four people were killed and around 300 injured in clashes when Venezuelan troops on the country’s borders prevented the delivery of aid over the weekend.

Sanctions or intervention. US hawks including Marco Rubio, who on Sunday posted a chilling tweet with a photo of a bloodied Muammar Gaddafi, appear open to military action, but the Trump administration has remained cautious. Spain, the former colonial power, has warned that it will not back any sort of military intervention.

The British prime minister Theresa May has said her job is not just to take the UK out of the European Union but to pursue her domestic agenda beyond Brexit, although she refused to reply when asked whether she would resign by Christmas. May struck a note of defiance and dismissed pressure to step down after sparking a fierce backlash by delaying a “meaningful vote” on the Brexit deal.

May day. Businesses have lost faith in the political process, the Institute of Directors has warned, with confidence in the service sector plunging amid uncertainty and fears that the UK could leave the EU without a deal.

An Australian cartoon of Serena Williams widely condemned as discriminatory was not racist, the Australian media watchdog has ruled. It had showed her jumping in the air and “spitting the dummy” after losing a match.

Three years ago, academics analysed almost 2,000 stories, concluding that there were six “core trajectories” for all stories. But what constitutes plagiarism? According to Twain: “substantially all ideas are second-hand”, while TS Eliot claimed “immature poets imitate; mature poets steal”. You decide.

Say what you will about Trump, his tactics on North Korea are working

The US president has been mocked for his cringeworthy photo opportunities with Kim Jong-un, but if he achieves denuclearisation then he will silence the jeers, William M Arkin writes.

Say what you will about Trump, but after some very bad years of active nuclear testing and missile shooting, disarmament on the Korean peninsula has already occurred. Things are quieter and two leaders who previously weren’t talking – ever – now are.
