Green Party leader Natalie Bennett failed to gain her seat in the constituency of Holborn and St Pancras.
The Labour safe seat has been represented in the Commons since 1983, most recently by Frank Dobson. Natalie Bennet came third, with Keir Starmer for Labour coming in first.
Bennett, who finished third with 12.8% of the vote, said: “I am immensely proud to have led the party into a general election where we have been able to stand more Green candidates than ever before and saved a record number of deposits. I’m also very pleased to have won a record result here in Holborn and St Pancras – the constituency I’m proud to call my home.
“Our astounding membership surge in the last year, which means the Green Party now has more members than both Ukip and the Liberal Democrats, has helped deliver tonight’s excellent results.
“The Green Party are the only party that truly stands up for what they believe in and I am delighted to see our commitment to deliver a fair economy, a public NHS and a safe climate has resonated with so many voters. The people have demonstrated their desire to see real change for the common good.”
