British Prime Minister Theresa May has seen off a threatened backbench rebellion to pass legislation that will pave the way for Brexit.
Pro-Europe rebel leader Dominic Grieve called off the revolt saying he was now satisfied parliament would get a say on what to do if negotiations fail.
Brexit negotiator David Davis said he needed a free hand.
"In trying to head off no deal, you actually make no deal more likely," he said.
In the end just six Conservatives voted against the government.
