Ed Miliband addressed the crowds in Hyde Park on Saturday:
"We come in the tradition of movements that have marched in peaceful but powerful protest for justice, fairness and political change.
"The suffragettes who fought for votes for women and won. The civil rights movement in America that fought against racism and won. The anti-apartheid movement that fought the horror of that system and won.
"The cause may be different but in coming together today to realise our voice, we are standing on the shoulders of those who have marched and struggled for great causes in the past.
"Our struggle is to fight to preserve, protect and defend the best of the services we cherish because they represent the best of the country we love.
"We know what the government will say: that this is a march of the minority. They are so wrong.
"David Cameron: you wanted to create the big society. This is the big society. The big society united against what your government is doing to our country.
"We stand today not as the minority, but as the voice of the mainstream majority in this country."
