Gardaí have warned of significant traffic disruption in Dublin and other locations nationwide throughout Saturday due to protests planned by the Irish Congress of Trade Unions.

The marches are intended to highlight the need for reductions in Ireland's debt burden.

Congress General Secretary David Begg has urged the public to attend.

Mr Begg said that while this week's deal on promissory notes was an important step, Ireland was still nowhere near solving its financial problems.

He said the debt burden on the Irish people was still unsustainable and unjust.

Last week, Mr Begg said he hoped between 80,000 and 100,000 people would attend the Congress protests.

In Dublin marchers will leave Cook Street at 1.30pm - and move along Winetavern Street, Dame Street, Nassau Street to Merrion Square, where a rally will take place.

Gardaí say the march could take two hours to cover the route, resulting in considerable traffic disruption.

There will be further marches in Cork, Galway, Sligo, Limerick, and Waterford.
