The top stories on Newstalk.com this morning

The row over water charges appears to have escalated again this morning.

The Fianna Fáil leader has indicated the party will not support the election of a new Fine Gael Taoiseach - unless the 'confidence and supply' arrangement that's propping up the minority government is honoured in relation to the charges.

The Sunday Independent has reported that Micheál Martin has written to Fianna Fáil TDs and Senators to outline the new position.

Fine Gael and Labour are claiming Ireland will face massive EU fines if some form of charge for excessive usage is not introduced.

But Fianna Fáil thinks people who waste water should be pursued through the courts.
