"Brexit is not orange or green. Brexit affects us all equally" and it brings "the same jeopardy" to everyone in Northern Ireland, Sinn Féin Deputy Leader Michelle O'Neill has said.
She was speaking after representatives from four pro-remain Northern Ireland political parties met Taoiseach Leo Varadkar and Tánaiste and Minister for Foreign Affairs Simon Coveney at Government Buildings in Dublin.
Ms O'Neill described the meeting as "positive" where they sought assurances on what has been achieved in the draft Brexit agreement.
The four parties say they speak for the majority of people in Northern Ireland and they want to protect the Good Friday Agreement, have permanency in the backstop, no room for a unilateral withdrawal by the British Government.
She said that "this has been unilaterally achieved" so they are broadly positive about what has been decided.
SDLP leader Colm Eastwood said "right now it is important for us to bank the backstop. This is what we asked for. We asked for the insurance policy to make sure that there will be no hard border in Ireland. The Government deserve credit for that."
He added: "I would appeal to people in Westminster. I know you have your own constituencies, your own political machinations to go through but we have a responsibility and everyone has a responsibility to avoid a hard border in Ireland.
"We cannot again see a hard border on this island. We cannot risk the peace and the progress that we have made. And we cannot make Northern Ireland an economic blackspot."
Steven Agnew, Green party leader said the backstop proposals have "alleviated the worst fears of what could result of our people from Brexit.
"We now need people in Westminster to put aside their political differences to come together and insure this backstop and there is no hard border."
Stephen Farry of the Alliance Party, said: "It is important that people are calm and measured. This is not the perfect deal for Northern Ireland but it is a good deal for Northern Ireland."
He called for a cool and rational response as this does not affect the constitutional position of Northern Ireland.
He also called on the Northern Ireland business community to speak out over the coming days. This deal has the potential for us to have the best of both worlds. It will be a bridge between the market in Great Britain and the European Union and a source of potential investment."
Ms O'Neill acknowledged there is an unpredictable situation in Westminster and "none of us have a crystal ball."
Mr Eastwood moved to reassure unionists by saying that it is written large in this agreement the constitutional integrity of Northern Ireland is there until the people decide to change that.
Ms O'Neill said: "What has been achieved so far is no border on the island of Ireland and that is significant.
"I think it is time for calm heads, for people to be cool, be reflective and to take a look at the deal. To go and analyse it properly and stop incendiary language coming out the of the DUP for the last 24 hours."
She added: "Brexit ... affects us all exactly the same way. It brings the same jeopardy to each and every one of us, in terms of future prosperity, our economy, our livelihoods.
"This is not a orange or green issue. We stand together representing a cross-community section of people. "
