The British Prime Minister says her government will not re-open the Good Friday Agreement.
In Theresa May's 'Plan B' statement to the House of Commons, she also ruled out a second Brexit referendum.
She told MPs that extending Article 50 would not rule of a "no deal" Brexit and would go against the referendum result.
The UK leader added that she will continue to meet with all sides of the House, including the DUP, to try to find the broadest possible consensus.
She says she'll then take the conclusions of those discussions "back to the EU".

Reports over the weekend also suggested she was looking for a bilateral treaty with Ireland, that would mean the backstop could be left out of the withdrawal deal.
But Mrs May says that the Belfast Agreement remains in place.
"All of us agree that as we leave the European Union we must fully respect the Belfast Agreement, and not allow the creation of a hard border between Northern Ireland and Ireland - nor indeed a border down the Irish Sea.
"And I want to be absolutely clear in the light of media stories this morning: this government will not re-open the Belfast Agreement, I have never even considered doing so and neither would I".
It comes only days after MPs overwhelmingly rejected her EU withdrawal deal.
