Tens of thousands of anti-Trump demonstrators gathered in cities around the globe on Saturday, as the impact of tariffs and cuts to government agencies galvanised the first big wave of protest against the administration.

The rallies came days after Trump upended the global economy by using rarely invoked emergency powers to unleash tariff hikes on almost every country in the world, wiping out about $2.5tn of market value on Wall Street.

Those who attended the protests cited a list of administration policies, from the aggressive trade levies, lay-offs across the federal workforce, deportations of legal immigrants, attacks on the transgender community, and threats to invade Greenland, as well as Elon Musk’s so-called Department of Government Efficiency.
