Looks like A50 before end of March is going to require some overtime
https://www.theguardian.com/politics...uk-brexit-billTheresa May’s government has vowed to overturn a demand by the House of Lords to guarantee the rights of EU citizens living in the UK within three months of article 50 being triggered.
Ministers were said to “disappointed” by a heavy defeat in which peers voted 358 to 256 in favour of amending the Brexit bill, but made clear that their position would not change on the issue.
Seven Conservatives including the former cabinet minister Douglas Hogg lined up with the Labour party, Liberal Democrats and crossbenchers to demand formal reassurances for more than 3 million Europeans already resident in Britain.
There will now be intense pressure on Conservative backbench MPs to follow suit when the bill returns to the Commons for another vote in just under a fortnight.
