Liz Kendall has called on Labour to reach out to the public by contacting millions of voters and asking them to take part in the leadership contest. In a letter to the party’s General Secretary Iain McNicol, Kendall urges Labour to adopt a strategy of contacting every person identified as a supporter since 2010 and asking them to sign up as members, registered supporters or affiliated members.

Under new rules, people will be able to sign up as a supporter for £3 and vote in this summer’s leadership vote. While membership has risen substantially since the election, to over 220,000, reports suggest that there has not been a big uptake in the number of registered supporters and affiliated members.

Since January alone, Labour Party activists spoke to over five million voters on the doorstep – over the past five years, that number will be considerably higher. Now Kendall wants the party to contact each one of those who identified as a Labour supporter and let them know how they can take part in the current “debate about how Labour renews itself”.
