Party leader, Sophie Walker, said: "This year I want to lead a party and a movement of women and men who will stand strong in the face of racism, sexism, homophobia and all other kinds of discrimination.

"We must unite to protect our rights in the face of a US administration and uncertain Brexit negotiation.

"We must protest an environment in which many minorities feel threatened.

"We must build tolerance and diversity at all levels of society."

The march, which started at midday at the US Embassy has been deemed a "peaceful" demonstration.

Organisations have urged it is a "peaceful" demonstration and people should come with an "open mind and an open heart".

Leader of the Women’s Equality Party and former London Mayoral Candidate Sophie Walker leads the way with party banners reading: “Reject hate. Reclaim politics”

She said: “There is a temptation to respond to Donald Trump’s presidency as if this were business as usual. This is not business as usual,” says WE party leader Sophie Walker.

“This march is a show of strength in the face of racism, sexism and misogyny unleashed during the US presidential campaign and, here, the debate over Brexit.

The intolerance and divisiveness that characterised the politics of 2016 must not be allowed to poison the world for years to come.

We march to reject the rhetoric of division and hate, and the rise of xenophobia in this country and around the world. We march with all those who are marginalised and threatened by the politics of fear, standing side by side to show that this year marks the start of a new politics of inclusion and tolerance.”

Sadiq Khan set to join Women's March London

The Mayor of London, Sadiq Khan, said he will be joining the march through central London to support women’s call for equality in light of Trump’s presidency.

He said:

“As a feminist in City Hall I fully support the fight for gender equality. It’s wrong that in 2017 someone’s life chances and fundamental rights are still dependent on their gender.

In recent decades we’ve made good progress, but there is still so much more for us to do and we must redouble our efforts to make sure that as we strive for equality we do not lose all that we have achieved.

As I march today I am more determined than ever to do everything I can to ensure that all girls growing up in London have the same opportunities in life as men.”
