Thousands of people have gathered in central London to demonstrate against the UK government’s economic policies.
The protest has been organised by a group called the People’s Assembly Against Austerity.
Crowds met outside BBC Broadcasting House in Portland Place, before marching past Downing Street and on to Parliament Square.
The Labour leader Jeremy Corbyn is among the speakers who will address crowds at The Not One Day More protest.
The crowd chanted “oh Jeremy Corbyn” and “Tories out” during the rally, while many carried banners saying Justice For Grenfell.
Speaking in Parliament Square, shadow chancellor John McDonnell promised to support the victims of the Grenfell Tower fire, which is believed to have killed at least 80 people.
He said: “We will not rest until every one of those families is properly housed within the community in which they want to live.
“Grenfell Tower symbolised for many everything that’s gone wrong in this country since austerity was imposed upon us.”
One protester told BBC News that “anger” had motivated her to join the protest, saying: “What’s going on isn’t good enough under the Tory government.
“There have been cuts to every single service you can think of. It’s just the pure negligence. How can you be cutting vital services?”
The organisers said on Facebook that they “invite everyone – from campaigns and community groups across the country, from the trade unions, from political parties and any individual – to come together in one massive show of strength and solidarity”.
The statement added: “We’re marching against a government committed to austerity, cuts and privatisation.
“We’re marching for a decent health service, education system, housing, jobs and living standards for all.”
Downing Street did not want to comment on the protest.
