Famously, according to the advertising slogan anyway, Guinness is good for you. But for the past couple of years, Guinness has been practically inescapable.

Backed by its owner Diageo’s £2.7bn marketing war chest, the brand has shaken off its “old man” reputation, becoming a staple of gen Z pub culture, exploiting its Instagrammable colour scheme and social media trends such as the “splitting the G” drinking game.

The president’s inability to tell right from wrong fuels his increasingly dictatorial, illegal and erratic behaviour

Donald Trump made 30,573 “false or misleading” claims during his first term, according to calculations published in 2021 by the Washington Post. That’s roughly 21 fibs a day. Second time around, he’s still hard at it, lying to Americans and the world on a daily basis. Trump’s disregard for truth and honesty in public life – seen again in his despicable response to the fatal shooting in Minneapolis – is dangerously immoral.

Trump declared last week that the only constraint on his power is “my own morality, my own mind”. That explains a lot. His idea of right and wrong is wholly subjective. He is his own ethical and legal adviser, his own priest and confessor. He is a church of one. Trump lies to himself as well as everyone else. And the resulting damage is pernicious. It costs lives, harms democracy and destroys trust between nations.

Residents battle bitter winter cold inside unheated apartments; Ukraine confirms UN to hold emergency meeting Monday on Russian ballistic missile attack. What we know on day 1,418

Engineers in Kyiv scrambled on Saturday to stabilise a power grid brought to the brink by a campaign of Russian strikes, including one two nights ago. The city’s residents huddled against bitter winter cold inside their unheated apartments on Saturday as engineers worked to restore power, water and heat. Prime minister Yulia Svyrydenko said that the power situation in the capital was still difficult, as the grid was badly damaged and people were using more electric heaters because of the cold.

Ukraine’s foreign minister Andrii Sybiha confirmed Saturday the UN security council would hold an emergency meeting on Monday to discuss Russia’s latest large-scale attack on Ukraine, which used an Oreshnik intermediate-range ballistic missile. “The meeting will address Russia’s flagrant breaches of the UN Charter,” Sybiha wrote on X.

Stéphane Dujarric, spokesperson for the UN secretary-general, said major attacks by Russia on Friday “have resulted in significant civilian casualties and deprived millions of Ukrainians of essential services, including electricity, heating and water at a time of acute humanitarian need.”

Ukrainian president Volodymyr Zelenskyy said Ukraine’s lead negotiator Rustem Umerov spoke with representatives of the United States on Saturday as Kyiv and Washington seek to agree on a framework to end Russia’s war in Ukraine. “We continue to communicate with the American side on practically a daily basis,” Zelenskyy wrote on the Telegram app.

The governor of Russia’s Belgorod region, which borders Ukraine, said on Saturday that 600,000 residents were without electricity, heating and water after a Ukrainian missile strike. In a statement posted on Telegram, Vyacheslav Gladkov said that work was under way to restore supplies, but that the situation was “extremely challenging”.

A Ukrainian drone strike sparked a fire at an oil depot in Russia’s southern Volgograd region, officials said Saturday. Ukraine’s General Staff said Saturday it had struck the Zhutovskaya oil depot overnight. In a statement on Telegram, it said the depot is supplying fuel to Russian forces, adding that damage was being assessed. Ukraine’s military said that besides the oil depot in Volgograd, it had struck a drone storage facility belonging to a unit of Russia’s 19th Motor Rifle Division in Zaporizhzhia, southern Ukraine, as well as a drone command and control point near the eastern city of Pokrovsk.

An overnight Ukrainian drone attack injured at least four people and damaged several buildings in Russia’s southern city of Voronezh, the governor of the Voronezh region said on Sunday. An emergency service facility, seven apartment buildings and six houses were damaged as a result of the attack, the governor, Alexander Gusev, said on the Telegram messaging app.

Russia’s defence ministry said Saturday that its forces used aviation, drones, missiles and artillery to strike Ukrainian energy facilities and fuel-storage depots on Friday and overnight. It did not immediately specify the targets or damage.
