Mr McGuinness said: “I met today with the Irish and British governments to impress on them the need for the democratic vote of the people of the North to remain in the EU to be recognised and respected.
“This is not a done deal.
“There is still a lot to be played for and we will be asserting the rights of those who voted to remain in Europe.
“The Irish government needs to represent the democratic will of the people of the North and to work in the best interests of all Irish citizens.
“Sinn Féin will continue with our campaign to secure and win a referendum for Irish unity,” added the Foyle MLA.
