The rally, titled 'Not One Day More #ToriesOut', started at BBC Broadcasting House in Portland Place and finished at the Houses of Parliament in Westminster.
Before the event, at least 10,000 people said on Facebook they would attend the protest organized by the People's Assembly Against Austerity (PAAA) group.
"Theresa May called the General Election to gain a bigger majority, and despite massive media bias in favour of the Conservatives, she failed spectacularly to deliver on that," a PAAA statement reads.Labour Leader Jeremy Corbyn addressed the crowd at Parliament Square.
"Now the Tories are in chaos trying to prop up a government with the deeply conservative and regressive DUP."
"We're marching against a government committed to austerity, cuts and privatisation," the group adds. "We're marching for a decent health service, education system, housing, jobs and living standards for all."
