Prime Minister Theresa May is in "listening mode" and there is optimism that a Brexit deal can still be reached, the DUP has said after meeting the PM on Thursday morning.
Party leader Arlene Foster and her deputy Nigel Dodds spoke with Mrs May, who is holding talks with parties from across parliament as she seeks to reach a consensus on Brexit.
Mr Dodds said engagement with Mrs May had been "good" and talks would continue.
Mrs Foster said the DUP did not want to provide a running commentary on the issue but believed the party had made a "clear ask" in relation to its concerns around the Irish border backstop.
"She has a way through this... address the backstop in a satisfactory way," added Mr Dodds.
