Water charge campaign group Right2Water has said it will hold the "biggest demonstration in the history of the State" on the weekend before the forthcoming general election.

Spokesman Brendan Ogle said the demonstration would ensure that when people go to the polls, the water charge issue will be at the forefront of their minds

He was speaking ahead of a series of protests planned for this Saturday. 27 events are planned for across the country

Mr Ogle said water charges are an economically inefficient imposition on the public and called for people to come out and support the protests.

He said households use only 10% of water but have to pay 78% of all the costs while corporations and agriculture use 90% but will pay only 22% of costs.
