It was the first Mayoral selection process since 2002 not to feature Ken Livingstone as a candidate.

To proceed in the Labour selection process, each applicant had to secure the nomination of at least five Constituency Labour Parties (CLPs) in the London region.

Nominations were decided at open meetings of local parties, with all Labour members and registered/affiliated supporters within that CLP eligible to vote in person.

[1][2] The results were as follows: Keran Kerai and Neeraj Patil received no CLP nominations and were therefore eliminated from the contest.

Between 14 August and 10 September, affiliated and registered supporters and members of the Labour Party in London were able to vote.
