MPs voted by 329 to 300 to back a bill aimed at blocking a no-deal.
More Tories rebelled at British Prime Minister Boris Johnson and voted with opposition parties.
The Foyle MLA said that local MPs who stood with Johnson or failed to take a stand at all have abdicated responsibility.
He said: “Once again, as the interests of people, communities and businesses on this island hang in the balance, our MPs, with the exception of Sylvia Hermon, are either standing on the sidelines or supporting the opposition team.
“It isn’t good enough.
“It’s a strange state of affairs when we’re relying on arch Tories to stand against their leader instead of the MPs elected to represent our communities.
“Boris Johnson’s successive defeats as Prime Minister are welcome.
“MPs from all parties should unite to oppose a no-deal Brexit.
“When that threat has been fought off, an election is necessary to finish off this Tory/DUP government.”
