Students mostly pro testing a rise in fares.

Ah, heavy handed response from security personnel lead to stunning scenes of mass protests in the streets of Santiago and other Chilean cities.

Dozens died during riots, arson and looting that caused extensive damage and prompted a military presence on the streets.

Okay, but the peaceful protesters persevered, calling for an overhaul of Chile's social and economic model and gaining a key demand.

Ah, vote on whether to toss out the old Magna Carta, the constitution adopted during the brutal 17 year dictatorship of General Augusto Pinochet, which ended in 1990 a period when thousands were tortured, killed or they were disappeared.

This'll be a historic event.

For the first time in the history of the republic, we will be consulted on whether or not we want a new constitution and who should draft it, Director.

The subway stations were cleaned up after the demonstrations and rioting a year ago, but emotions have been peeking again.

Peaceful anti government demonstrations last Sunday were marred by the burning of two churches Vandals cheering the collapse of a church spire, not what those promoting a yes vote on a change to the constitution, want their protests to be remembered for.

We're not seeing any change.

Healthcare is the same pensions.

That's what we're fighting for for more than a year.

Our pensions or wages or education, everything.

But I don't see any change.

After a year of the social upheaval, I am out in the street because I want changes to our health system.

On the other side, thousands have hit the streets to protest against change.

No, they say toe a rewrite of the constitution by shifting to a new constitution were in great danger of falling into something like what happened to Venezuela.

If it happened to Venezuela, why wouldn't happen to us?

We'll keep the same constitution and make the necessary reforms to it.

No voters insist the government working within the present constitution will help those left behind since the Magna Carta was adopted.

Yes, voters say, start from scratch with the participation of the people and let the world see what Chilean democracy to looks like.

Body W's Johan Ramirez joins us from the Chilean capital, Santiago Johan.

What's at stake in this referendum tomorrow Chile will define whether or not they want to have a new constitution on Also, they will choose through which mechanism they want.

This new constitution to be drafted.

Uh, more than 15 million people are called Thio Vote tomorrow after ah, year off massive protests that have been held in the same place The place Italian Italy Square That has been the main hot spot after protests today.

It was very calm during the day and now as the evening con, uh, we have seen some people protesting against the police, Some people throwing rocks against the police on the police and military is moving around to prevent any clash in this day, just Ah, few hours before the referendum take place here in initially now a.

Your referendum has been one of the key demands from the protesters.

Why are they so opposed to the current one?

One of the main critics that people do against this constitution is the legitimacy off the origin off the Constitution.

It was written during the dictatorship off Agusto Pinochet more than 30 years ago.

It was written for people who was not choose shows by the people in electoral event.

Uh, in a time where there were not free press, the international observers.

So it's, ah, legacy off the dictatorship on there are many things, many public policies that cannot be taken.

They cannot take place because off this constitution.

So the main social changes that need Chile are in a way blocked because of this constitution.

Now, if Chileans vote in favor off the new constitution on Sunday, are we likely to see an end to the anger?

It doesn't look like.

I mean, there are many problems like ground problems in Chile.

There are beyond this Constitution.

I mean, Chile needs really, uh, important public policies to change the health system.

Uh, many other things.

Education, uh, for all people on these things cannot be changed just because off a boat is a first step.

But it will change the framework off the state.

But the the hurt off the problems are public policies.

For that we need also the will off politicians on as I tell you right now, we will listen already the clashes people throwing rocks against the police on we we felt already a little bit the pepper gas that maybe the police are start moving around because the vote tomorrow is very important.

But it won't change the main problems off the country.

No, from one day to another.

Thank you, Johann.

Johann Ramirez there in Santiago.
