By the midnight February 14 deadline, Thornberry had only secured 31 nominations from local constituency parties - two short of the 33 obligatory nominations.
Thornberry’s elimination leaves only three candidates in the race to succeed outgoing leader, Jeremy Corbyn.
The leading contenders are the shadow business secretary, Rebecca Long-Bailey, and the former shadow Brexit secretary, Keir Starmer. The former shadow energy secretary, Lisa Nandy, has also made it to the last stage of the leadership race.
The three candidates represent different political wings and ideological strands of the Labour party, Presstv Reported.
Long-Bailey is a left-winger and Corbyn ally but she denies being a “continuity” candidate and to that end she has tried to set out an original political canvass.
Long-Bailey is popular with the unions – historically the most important pillar of the Labour party – as well as with the most energetic segments of the party rank and file. Indeed, she enjoys the support of the campaigning and pressure group Momentum
By contrast, Keir Starmer represents the party’s centre ground, at least in policy terms. A former director of public prosecutions, Starmer is more popular with the parliamentary Labour party than with the party’s the rank and file.
Meanwhile, Nandy is situated in the right wing of the party and she has been critical of most of Corbyn’s policies.
Online and postal ballots of Labour party members and registered supporters open on February 24 before the final result is announced at a special conference in London on April 04.
