"I tested positive yesterday for Covid-19. I'm as well as I can be, strictly confined to my home," Barnier, 69, said in a video posted on his Twitter account. "I'm fine, morale is good," added the former French foreign minister, who is in France.
"I naturally am following all instructions, as does my team. My message to all those who are affected or currently isolated: we will get through this together!"
Barnier's revelation comes after the EU and Britain on Monday cancelled this week's post-Brexit trade talks because of the coronavirus outbreak.
