Edwin Poots might not guarantee an Irish language law this term
DUP leader - Edwin Poots - has said he wants to support Irish language legislation, but not necessarily before the following assembly election.
Sinn Féin has made suggesions that it may not support a brand new DUP first minister unless such legislation is approved by ministers before the 10th of July.
Arlene Foster will resign as first minister later on Monday.
Sinn Féin's Michelle O'Neill will lose her position as deputy first minister because the roles are a joint office.
As soon as Mrs Foster resigns, there shall be a seven-day period for the approval of a brand new first minister and a deputy first minister by Sinn Féin, and the Democratic Unionist Party (DUP).
Her departure is after six weeks after she was overthrown as the leader of the DUP.
Mr Poots said he will chose his colleague - Paul Givan - to become the new first minister.
But speaking on the BBC's Good Morning Ulster programme on Monday, Mr Poots said he was not sure whether the nomination would happen on Monday.
He said it would be up to the speaker to decide, but anticipated it would be within "the next couple of days".
Sinn Féin must choose a candidate for deputy first minister or a first minister is unable to take office.
Mr Poots said he remained commited to the New Decade - New Approach agreement, which committed the parties to creating an Office of Identity and Cultural Expression including provision for services for Irish and Ulster-Scots.
Though, he said "time will tell" if it would happen in the current assembly term, which will expire in April 2022.
