This is the text of the letter David Cunliffe sent to Labour members, supporters and affiliated unions on Saturday night, after the party's shocking election result.
In it, he seeks their support to remain leader of the Labour party.
"Thank you. Over the last weeks and months, we put everything into this campaign. It was always going to be a challenge to overturn this Government in less than a year, but I am immensely proud of the campaign we've fought together.
The thousands of you I have met over the last few weeks have reminded me how important it is to hope for a better future, and to believe in the great people of our country. The Labour Party is a movement of positive people - I'm glad that our policies and strategy reflected that this election.
From the volunteering, to the fundraising, to the huge social media effort - Labour supporters across the country have given it their all, and each day have reminded me why I love the Labour Party: that solidarity is something we live and breathe.
