The shadow foreign secretary narrowly fell short of getting the support of 33 local Labour branches by the deadline on Friday night.
Just hours before nominations closed, the Islington South and Finsbury MP, had written on Twitter: “Your CLP can make all the difference!
"Nominate me to get the widest range of voices, skills and experience on the ballot. Labour members deserve to have the widest and best possible choice when deciding our next leader.”
But her eleventh hour plea was not enough to keep her in the race. It means she will not get her name on the ballot paper that goes out to members, who have until 2 April to vote for Jeremy Corbyn's successor.
We are in a climate emergency. We need a leader who is prepared to take the bold action needed, and stand up to those who hold us back. #climatestrike
