Grind, Grind, Grind: Brexit Talks Soldier on, Summit Looms Associated Press BRUSSELS - The European Union and Britain saw their chances of reaching a full Brexit divorce deal by Thursday's EU summit diminish by the hour Wednesday as legal issues centering on the Irish border frustrated negotiators. Hopes were increasingly turning toward getting a broad political commitment to a Brexit deal between British Prime Minister Boris Johnson and the 27 other EU leaders at this week's summit, with the legal details hammered out later. That could mean yet another delay to Britain's departure, currently due to take place on Oct. 31. It also raises the prospect that the EU need to hold another Brexit summit before the end of the month. "The 31st of October is still a few weeks away and there is a possibility of another summit before that if we need one," Irish Prime Minister Leo Varadkar said in Dublin. The British government, meanwhile, insisted the U.K. would still leave the EU on Oct. 31-- but also promised to obey Parliament's order that it must seek a delay to Britain's Brexit departure date if no deal is in place by Saturday. "I can confirm, as the prime minister has repeatedly set out, that ... the government will comply with the law," Brexit Secretary Stephen Barclay told British lawmakers on Wednesday. The EU already struck a Brexit divorce deal with former British Prime Minister Theresa May, but that was rejected three times by British lawmakers. With that experience in mind, EU leaders are seeking reassurances from Johnson during this week's summit that he has the political weight to push any new deal through the House of Commons. The Brexit talks plodded ahead Wednesday, further delaying preparations for the EU summit. Since the weekend, negotiators at the EU's glass-and-steel headquarters in Brussels have been locked into long sessions on how to deal with detailed customs, VAT and regulatory issues under British proposals to eliminate border checks between the U.K.'s Northern Ireland and EU member Ireland. "Talks have been constructive but there still remains a number of significant issues to resolve," EU Commissioner Dimitris Avramopoulos said after being briefed by EU Brexit negotiator Michel Barnier. Both sides were hoping that after more than three years of false starts and sudden reversals, a clean divorce deal for Britain leaving the bloc might be sketched out within the coming hours. .
