On 25 March 2019, the UK House of Commons passed the Letwin Amendment, which stated, in part:
Standing Order No. 14(1) (which provides that government business shall have precedence at every sitting save as provided in that order) shall not apply on Wednesday 27 March;
There were a lot more details in there that I don't understand, but I got the point that parliamentary business would follow Letwin's plan on 27 March, and it did.
Now I'm given to understand that parliamentary business will follow Letwin's plan again on 1 April. How is this being accomplished technically, in terms of parliamentary rules? Nothing in the original amendment mentioned 1 April.
A comprehensive answer to this question would explain all of the following, but I'd be happy with answers that explain any of the following:
- How is parliament's business normally set, and what rules control it?
- What rules does the Letwin Amendment override, and what does it replace them with?
- Was there some motion passed mentioning 1 April? If not, how did it get selected as the next Letwin-guided date?
- Will there be more Letwin-guided dates after 1 April? Who will decide and how?
