Last week, 1,000 protesters gathered outside 10 Downing Street for a spontaneous demo demanding
Mr Cameron's resignation over the Panama Papers scandal. Today, The People's Assembly organised an anti-austerity protest that attracted over 100,000 people. In fact, some reports are claiming 150,000.
The March for Health, Homes, Jobs and Education does exactly what it says on the tin.
They have four demands.
Now I am not a religious man what so ever. But when 10's of thousands of people walked into Trafalgar Square, on what was supposed to be a very wet day but the sun broke thought. Well it was almost a biblical vision, and my eyes welled up as did many others.
The demonstrators called for an end to austerity, and demanded that David Cameron quit over the revelation that he profited from his father's offshore investment fund.
Dianne Abbott MP addressed the massive crown along with junior doctors involved in organising strikes against the new contract that Health Secretary Jeremy Hunt is seeking to impose.
Ms Abbott said: "I'm so glad to be here to pass on Jeremy Corbyn's absolute support for this demonstration. There couldn't be a more important movement and demonstration than this one today.
"Austerity is a threat to the National Health Service and to our public services. We must unite to defend them."
Shadow Chancellor John McDonnell, union chief Len McCluskey and Green Party leader Natalie Bennett also took part in the march once it arrived with at Trafalgar Square. Mr McDonnell said: "Alongside courage and determination, we need solidarity. The workers united will never be defeated."
He added later: "I think Cameron should go, but I think he should take his party with him. His Government is now bankrupt in terms of political ideas, and bankrupt in terms of what they have done with the economy as well.
"On every front now we are seeing the Government in disarray - in terms of the economy we are slipping backwards instead of growing."
The People's Assembly used the protest to make "Four Demands". With regards to health, they called for an end to Government spending cuts and the alleged privatisation of the NHS. The protestors' demand over housing included rent controls and the protection of social housing.
On jobs, they called for a universal living wage and the scrapping of the Trade Union Bill, and they also demanded an end to student tuition fees and "the marketisation of education".
Probation worker Michaella Hagger, 27, said: "I'm here because I hate David Cameron. It's all about the cuts, tax dodging, and the NHS for me. They are ruining people's jobs and making it impossible for everyone."
Also on the march was feminist protest group Sisters Uncut. They said: "Sisters Uncut are marching with student nurses for a society in which everyone has a secure livelihood, and no one is financially dependent on an abusive partner."
