Members of the Right2Water campaign say up to 88,000 protesters lined Dublin’s main thoroughfare for an anti-water charges demonstration yesterday afternoon.
The campaign which is led by political parties and trade unions said the protest was the biggest mass mobilisation of people the country has ever seen.
Brendan Ogle from Right2Water called the turnout "truly historic".
"It was the biggest mass mobilisation of people we've seen on any single issue, ever," he said.
He also said the upcoming General Election would be a game changer for the Coalition.
"People who are opposed to the water charges...are realising that if we put the same people back into the Dáil again, all the protests are a waste of time," he said.
"First of all we can protest. Second of all we can deliver change and third of all, if we really organise, we can get a different government."
