News that Vladimir Putin, Russia’s latter-day tsar, is making plans to cling to power indefinitely comes as no surprise. All the same, it is deeply worrying for Putin’s prey – principally the Russian people and the western democracies.

Putin, 67, has run Russia, as president and prime minister, for 21 years, a feat of political longevity surpassed only by Joseph Stalin. Like Stalin, he has made many enemies and caused untold misery along the way.

As Democrats marched the articles to the Senate, the president basked in policy success. Many think re-election is coming

It was, the White House tweeted on Friday, “an incredible week” for Donald Trump. On that, no one could disagree. But what kind of incredible depended on which end of Pennsylvania Avenue you were standing.

The pioneers who struggled for legalisation in the 60s are seeing the same battles being fought all over again

The telephone sat in the dormitory hallway, and when it rang it might have been for any of the residents – young women in their teens and early 20s, all students at the University of Chicago. Calls came from family and friends and boyfriends, from colleagues and classmates and clubs. But sometimes the voice at the end of the line would ask for “Jane”.

This was 1965, and in Chicago the social justice movement was gathering pace – a new era that encompassed civil rights, student rights, women’s rights and resistance to the war in Vietnam. Among those involved was Heather Booth, a 19-year-old social sciences student from New York. Booth had spent the summer of 1964 in Mississippi, volunteering as part of the Freedom Summer project, an attempt to register as many African American voters as possible. It was an experience that had galvanised her and taught some valuable lessons: “One is that if you organise, even in what seem like the most hopeless circumstances, you can change the world,” she says. “Number two: sometimes you have to stand up to illegitimate authority.”

Political activist Joshua Wong was 20 when he was sentenced in 2017 to six months for his role in Hong Kong’s pro-democracy ‘umbrella movement’

The last words I said before I was taken away from the courtroom were: “Hong Kong people, carry on!” That sums up how I feel about our political struggle. Since Occupy Central – and the umbrella movement that succeeded it – ended without achieving its stated goal, Hong Kong has entered one of its most challenging chapters. Protesters coming out of a failed movement are overcome with disillusionment and powerlessness.

His campaign feared hostility in Iowa’s most conservative county. But the local response told a different story

Pete Buttigieg knew he was foraying into unfriendly confines when he was en route to Orange City, the seat of Iowa’s most conservative county.

The gay ex-mayor of South Bend, Indiana, may be in the top tier of Democratic presidential candidates seeking to win this vital first voting state next month, but his sexuality was seen as likely to be a major issue in this corner of the state, Sioux county.

Sars-like virus has infected nearly 50 people in China, killing two, with cases also detected in Japan and Thailand

Australia’s top health official says there is “no current need” to enhance existing airport screening measures to target an unknown Sars-like virus that has infected nearly 50 people in China and killed two since it was reported on New Year’s Eve.
