Edwin Poots resigned, after around 20 days.
The new leader of the DUP could be known as early as tomorrow.
It comes after the resignation of Edwin Poots who only lasted three weeks as leader, after a row within the party.
Cliona O'Dwyer reports:
"The DUP has reportedly warned it'll collapse Stormont if there isn't a change in the proposals to introduce Irish language laws.
Nominations for a new leader opened on Saturday and their identity could be revealed as soon tomorrow.
Jeffrey Donaldson is the favourite to take the position.
It comes after Edwin Poots stepped down as leader after just three weeks in the job, over his deal on Irish language legislation.
Meanwhile, Edwin Poots is paying tribute to former North Down MLA Gordon Dunne MBE who has passed away.
Mr Poots says the news of his passing is a huge shock and Gordon will be sorely missed by everyone associated with the DUP. "
Northern Ireland Political Correspondent with the Irish Times, Newton Emerson feels the DUP won’t collapse Stormont over the Irish language.
Jeffrey Donaldson is expected to start a new bid to become the next leader of the DUP today.
He's likely to be unopposed - but the process won't be completed until Saturday.
British Conservative peer Lord Caine has advised several former Northern Ireland Secretaries.
