Millions of Women March Against Trump on All 7 ContinentsThe second day of the Trump administration has seen an unprecedented wave of protests swell across the globe, as the Women’s March on Washington and its sister marches on all continents — yes, including Antarctica — fight back against the U.S. president’s frightening rhetoric.

And with an estimated 500,000 marchers on the National Mall in Washington D.C., the Women’s March is now the largest inaugural-related protest in U.S. history.

Organisers, including the Women’s Equality Party, said an estimated 100,000 descended on central London with similar events taking place in Manchester, Edinburgh, Belfast, Liverpool and Cardiff.

Marches were also held around Europe including Paris and Barcelona.

Celebrities Katy Perry, Scarlett Johansson, Amy Schumer and Patricia Arquette were among demonstrators at the Washington event.

During the election campaign, Trump signalled his backing for plans to choke off funding for the organisation.
