PARIS — EU chief Brexit negotiator Michel Barnier said on Tuesday that the Brexit deal provided “some stability” and relief, even if he regretted it.“We’ve delivered an orderly Brexit in two steps, first the political and institutional divorce … then the economic and commercial divorce,” Barnier told Franceinfo radio. “Nobody can be happy about a divorce … it was painful, I regretted it, we all regretted it, but it’s a democratic decision,” he added. Clinching a deal before Christmas was “a relief” for people and companies, he said. “We have brought some stability with this agreement, but it is a big change,” Barnier said.The chief negotiator said the EU relationship with Britain was still needed in areas such as health, climate change and defense cooperation.Asked about his future, Barnier said he saw himself serving his home country, France, and the European project. “I want to meet the French again because I missed them these few years in Brussels,” he said.”Patriotic and European, this is what will characterize my future political commitment,” Barnier also told Ouest France in a wide ranging interview on Monday.
