Sinn Féin is organising protests throughout Ireland next Thursday to protest against the postponement of Assembly elections.
The main rallies will be outside the British embassy in Dublin and City Hall in Belfast. They will coincide with the date the elections were to take place, May 29th.
Announcing the protests, Sinn Féin's chief negotiator Mr Martin McGuinness emphasised that they should be peaceful.
Rallies have been organised for more than 30 cities and towns, including Belfast, Dublin, Cork, Galway, Limerick, Derry, Waterford, Sligo, Omagh, Enniskillen, Lurgan and Strabane.
Sinn Féin Assembly candidates will hand in letters of protest to electoral offices in Belfast, Derry, Ballymoney, Banbridge, Omagh and Glengormley in north Belfast.
The rally outside the British embassy on Thursday evening will have keynote speakers and involve musicians and street theatre.
Earlier in the day there will be a "protest flotilla" on the Liffey, according to Sinn Féin.
The British embassy protest may cause security concerns. The embassy was burned during protests after Bloody Sunday in 1972.
However, Mr McGuinness, while warning that the deferral of the poll had created "a very dangerous political vacuum", said a peaceful environment was required if the stalemate was to be eventually broken.
"The last thing that should happen on the streets is anything that would in any way endanger the peace process," he said. "Armed groups need to consider the reality that the politicians need to be allowed the space to sort all of this out," he said.
Mr McGuinness continued to accuse the British government of postponing elections at the behest of the Ulster Unionist leader, Mr David Trimble, who, he said, was not prepared to campaign on behalf of the Good Friday agreement.
He added, however: "We still need to work this out. We are very keen to see and work with a unionist leadership that is prepared to join with us in partnership to work out a new future for all of us on the island.
"The only way to develop all of that is in a peaceful environment, and that is what I would appeal to everybody within our society to ensure that we have over the summer period."
He encouraged a large turnout for the protests. "The cancelling of the elections is wrong. It is undemocratic. It is disenfranchising the people of the six counties.
"And it was taken against the wishes of those representing the majority of the electorate in the North and the Irish Government," said Mr McGuinness.
The SDLP will today announce a number of its protests against the postponement of elections, including a whistle-stop tour of Northern constituencies by party leader Mr Mark Durkan.
Meanwhile, the British government has set aside £4 million to compensate for election expenditure incurred by the parties.
Mr Seamus Magee of the Electoral Commission said parties would be entitled to compensation for a range of expenses, including "party political broadcasts, the preparation of manifestos, market research".
