The Lords have started their debate on the government’s Brexit legislation.
The bill brings the deal the government has made with the EU into UK law. Its passage is a vital part of the government’s plan to leave the EU on 31 January.
It was voted through the Commons last week and now comes to the Lords. Today they will vote on the bill in principle, at what is called the second reading.
Tomorrow, the bill will enter committee stage, where Lords can debate and vote on amendments to the bill.
If the bill passes without amendment, it goes for Royal Assent and becomes law. If it is amended, it will return to the Commons for further debate, in a process known as ping-pong.
Tonight there was a remarkable intervention by Viscount Ridley.
