Brexit bill timeline:
Feb. 20-21
Members of the House of Lords hold a two-day debate on the bill. Peers can raise concerns about possible amendments, although they won’t be voted on at this stage.
Feb. 27 and March 1
This the committee stage when proposed amendments are discussed in more detail.
March 7
The peers debate the final wording of the bill and vote on any possible amendments. These amendments go back to the House of Commons for its approval. The bill is passed back from house to house – the so-called ‘ping-pong’ period until they both agree on the details of the bill.
There is no exact timeline for this, though the Lords expects to send the bill to the Commons for the final time on the week of March 13. The government has said it expects to trigger the Article 50 formal departure by the end of March.
