A conclusion on the deal was expected on Wednesday, but the decision may now be delayed to next week, after the DUP said it would be inappropriate to conclude talks and announce a deal on the same day as a fire consumed a tower block in west London, killing 12 people.
Many European Union citizens would like to follow Britain in having a chance to vote on membership of the bloc, although fewer than one in five support leaving it.
British Prime Minister Theresa May was scheduled to meet the leader of a small Northern Irish Protestant party on Tuesday to save her premiership and avoid a second election that would thrust Brexit negotiations into turmoil. "It's our dominating theme today and will remain so over the weekend as bodies are recovered and we start to get a sense of the scale of the tragedy".

Amazon to buy Whole Foods for $13.7 billion
Moody's lead USA retail analyst, Charlie O'Shea, said the takeover is a transformative transaction for the entire retail sector. But Amazon's not going away and that will incite change, he said. "There's a ton of stuff they can do with this real estate".
"Depending on a hard or soft Brexit, that number might be slightly less than that, so it's going to be updated all the time", its United Kingdom chief executive Ian Stuart told BBC television.
"We never put timescales on when we expect a deal to be done and I'm not going to start now".
