LONDON, Aug 14 (Reuters) - Prime Minister Boris Johnson said on Wednesday that some British lawmakers who thought they could bloc Brexit were engaging in a "terrible" collaboration with the EU.

"There is a terrible kind of collaboration as it were going on between those who think they can block Brexit in parliament and our European friends," Johnson said in a "People's PMQs" question-and-answer session on Facebook.

"Our European friends ... are not compromising at all," Johnson said. He added that the longer the impasse continued, the more likely a no-deal Brexit became. (Reporting by William James, editing by Guy Faulconbridge)
