BRUSSELS, April 11 (Reuters) - European Commission President Jean-Claude Juncker said he was certain Britain would honour the "sincere cooperation" obligation and would in any case have little power to block key EU decisions on its own during a second Brexit lag until Oct. 31.
"We will have a Brexit with a deal. I'd prefer no deal without Brexit," Juncker told a news conference. (Reporting by Gabriela Baczynska; Editing by Sandra Maler)
