Wilson has recently said that his party's deal to support the Conservative government could be jeopardised by the Brexit negotiations and any attempt to "placate Dublin and the EU" could mean a withdrawal of DUP support.
British Prime Minister Theresa May and Commission President Jean-Claude Juncker met for a crucial working lunch Monday to discuss the U.K.'s offer in the Brexit negotiations.
An agreement that would commit Britain to maintaining "regulatory alignment" between Northern Ireland and Ireland after Brexit would make it easier to avoid a hard border but limit the UK's ability to change its economic regulations to strike new trade deals across the world.
With the clock ticking down to the March 2019 exit date, May is under pressure to start talks on its future trade ties by the end of the year to remove the cloud of uncertainty for companies that do business in the EU.
The comments came as British Prime Minister Theresa May made a diplomatic push in Brussels, where she was meeting with top European Union officials in an effort to break an impasse, especially in the thorny issue of the Irish border. Both sides would promise to keep the trading rules compatible.
"It's probably about 50/50 whether there will be agreement in the near future". "I'm very confident that we will reach agreement in the course of this week".
A British official, who spoke only on condition of anonymity in line with government policy, said overnight there were "plenty of discussions still to go" and instead of an initial Monday deadline for a breakthrough, the official called the talks now "an important staging post".
"We now have a common understanding on most related issues with just two or three open for discussion".
On Sunday, Ireland's deputy prime minister Simon Coveney revealed there is "hope" Monday's meeting between the EU and Mrs May will "result in a momentum" that can be carried into the European Council summit and allow progress on Brexit.
Both Scotland and Northern Ireland voted to remain part of the European Union in the referendum which was held in June 2016.
"The Irish Government leaked a document which isn't the case, as far as I can tell".
"Not every single question has to be answered but we need sufficient progress on these very sensitive issues".
Northern Ireland, as part of the United Kingdom, is set to leave the European Union under Brexit while the Republic of Ireland remains an EU member.
"Hopefully there might be a breakthrough tomorrow".
