Get ready for a ping pong ding-dong.
Today's the day! The beginnings of a momentous and arduous slog for Theresa May. She's given up salt and vinegar crisps for lent.
Not the best time to white knuckle such a daunting task with her Brexit plans facing their first true test.
Having sailed through the House of Commons Theresa May's Article 50 Bill will face it's sternest challenge yet as members of theHouse of Lords debate the status of EU citizens living in the UK after Brexit.
A motley coalition of Labour, Liberal Democrat and Conservative peers look likely to vote in favour of the Government giving assurances to the 3 million EU citizens in the UK inflicting the first Brexit bill defeat on the government.
Cue "ping pong".
This is the slightly bizarre state of affairs where Bills are passed backwards and forwards between the two Houses of Parliament to be voted on until an agreement is reached - it can quite literally mean the Bill being walked from one end of Parliament to the other and back again repeatedly until there is a version of the Bill that suits both the Commons and the Lords.
As it stands the amendment says:
"Within three months of exercising the power under section 1(1), Ministers of the Crown must bring forward proposals to ensure that citizens of another European Union or European Economic Area country and their family members, who are legally resident in the United Kingdom on the day on which this Act is passed, continue to be treated in the same way with regards to their EU derived-rights and, in the case of residency, their potential to acquire such rights in the future.”
If the government can't make the Lords back down altogether then expect them to try and reword the Bill so it includes reciprocal rights for UK citizens currently living in the EU.
All in all, this looks like a good old fashioned parliamentary ping pong ding-dong.
