Jeremy Corbyn
In January 2017, Corbyn announced that he would support a three-line plan to force Labour MPs in support of triggering Article 50, which would start the removal of the United Kingdom from the European Union. In response, many Labour members said they would vote against the bill. Tulip Siddiq, the shadow minister for early years, and Jo Stevens, the Shadow Welsh Secretary resigned in protest. On 1 February, forty seven Labour MPs went against Corbyn's plan on the second reading of the bill.
