In the run-up to the so-called Brexit vote, observers questioned whether the Labour Party’s pro-EU position would signal to constituents a loss of domestic political power.
The party’s upheaval began on Sunday, when Corbyn dismissed his shadow government foreign secretary, who he suspected of plotting an internal coup. This sparked a series of walkouts, with 11 members of the shadow cabinet, an alternative cabinet to the governing party that doesn't have legal power, resigning on Sunday, including the secretaries for health, education, voter registration, and environment.
Most of those who resigned criticized Corbyn's handling of the EU referendum and expressed a lack of confidence in his leadership. In a meeting on Monday, deputy Labour leader Tom Watson told Corbyn he has “no authority” among party loyalists in the parliament.
Labour MPs are set to discuss a motion of no confidence in Corbyn.
