The Oliver Letwin Agreement, also known as the Letwin Amendment, refers to a parliamentary motion adopted by the UK Parliament in March 2019. The amendment was proposed by Conservative MP Oliver Letwin as a means to prevent a no-deal Brexit.
The motion stated that the UK government would not put the Withdrawal Agreement to a meaningful vote until the necessary legislation to implement it had been passed. This essentially meant that MPs could not approve the deal until all the details had been worked out, removing the threat of a no-deal Brexit on the original Brexit deadline of March 29, 2019.
The Letwin Agreement was significant in that it marked the first time in over a century that the UK Parliament had successfully taken control of the parliamentary agenda, rather than the government. In doing so, it demonstrated the degree of discontent among MPs with the government`s handling of Brexit and their determination to prevent a no-deal scenario.
The Letwin Agreement also paved the way for the Benn Act, which required the government to seek an extension to the Brexit deadline if a deal was not agreed upon by October 19, 2019. This Act further cemented parliamentary authority over Brexit negotiations, to the frustration of the government and Brexiteers.
Overall, the Oliver Letwin Agreement represented a crucial moment in the ongoing Brexit saga. It demonstrated the political power of Parliament and its ability to shape the course of Brexit negotiations, and it ultimately prevented a no-deal outcome in March 2019.
