The House of Commons voted 494-122 in their final vote on the bill to trigger Article 50 of the Lisbon Treaty and formally begin the process for the United Kingdom to withdraw from the European Union.
What's next: It's the House of Lords' turn to debate and vote on the legislation. Because the bill passed the Commons with a huge majority and no amendments, the unelected Lords are now under pressure to approve it quickly.
The government's take: To the BBC: "If the Lords don't want to face an overwhelming public call to be abolished, they must get on and protect democracy and pass this bill."
