Ross Greer and Gillian Mackay, elected after 12.7% turnout, also vow to campaign on higher taxation of rich

• UK politics live – latest updates

The new leaders of the Scottish Greens, Ross Greer and Gillian Mackay, have promised to campaign for a universal income, free bus travel and higher taxation on the rich after winning a muted election contest.

Greer and Mackay, who were both backbench MSPs at Holyrood, were appointed co-conveners of the Scottish Greens after a noticeably low turnout of 12.7% – only 950 of the party’s 7,500 members voted after a low-key summer campaign.

Mississippi museum announces display on anniversary of boy’s murder, a pivotal moment in civil rights movement

The gun used in the lynching of 14-year-old Emmett Till is now on display for the public to see, 70 years after the killing.

The Mississippi Department of Archives and History unveiled the .45-caliber pistol and its holster during a news conference on Thursday, which is the 70th anniversary of Till’s murder.

After a stellar girl group career the singer is heading to London’s West End with the musical Hadestown, and will answer your questions

With an astonishing 21 Top 10 hits and charisma to spare, Girls Aloud were one of the biggest and brightest groups of the 00s – and Nicola Roberts, enigmatic and riveting, was a crucial element. As she heads to London’s West End in the musical Hadestown, she’ll be joining us to answer your questions.

Roberts was just 16 when she auditioned for the reality talent show Popstars: the Rivals, which whisked her from school in Runcorn, Cheshire, to pop fame. Stationed in Girls Aloud, the quintet hit Christmas No 1 with their debut single Sound of the Underground and the hits just kept coming: from quirky neo-rock’n’roll (No Good Advice, Love Machine) to chart-topping power ballads (The Promise, I’ll Stand By You) and melancholic pop such as Call the Shots, its poignant middle eight made unforgettable by Roberts.

This humanitarian catastrophe is barely of passing interest to Donald Trump. The curse of our times is how little we can do about it

Day 222 of Donald Trump’s presidency, and Russia’s war in Ukraine – which he promised to end on day one – shows no sign of having got the memo. This was not a single-use Trump promise; he made it at least 53 times. Yet the US president has failed to keep it, either literally or in his favourite manner: figuratively. Can you figuratively end a war? Not even, apparently.

What his most recent round of failure means, however, is that Trump is pivoting back to another war, the grotesquely horrifying and unlawful humanitarian catastrophe unfolding in Gaza. Not the way he’d phrase it, possibly. This week he swerved commenting on either Israel’s invasion of Gaza City or the mounting declarations that famine and starvation are clearly under way in the territory, and instead announced: “I think within the next two, three weeks, you’re going to have a pretty good, conclusive ending.” Righto. Trump’s recipe for an ending to the horror has hitherto seemed to resemble the famous business plan of the South Park gnomes. Phase 1: Collect Underpants. Phase 2: ?. Phase 3: Profit.

Trainer opens up on her midas touch in the market as she closes in on £1m in prize money for the first time

Eve Johnson Houghton has saddled three Royal Ascot winners, including a Group One, in the past eight years, having bought all three for a combined total of just under £30k, and as she set out on the business of buying next year’s two-year-olds at the Doncaster sales on Wednesday, the trainer made the process of equine bargain-hunting sound simple enough.

“I just like a nice horse,” Johnson Houghton said. “You’re looking for different things for different clients, but they’ve got to walk well and have a good outlook, and I have to forgive a few things as well, because they can’t be perfect specimens at my price.
