Tessa Jowell enjoys a 17 point lead over her nearest rival in a new survey asking Labour members and supporters who they’re backing as the party’s 2016 mayoral candidate.
Dame Tessa was named as the preferred choice of 35% of participants, almost double the 18% naming Tooting MP Sadiq Khan.
In joint third place on 12% were Diane Abbott and Christian Wolmar, followed by David Lammy on 9% and MP Gareth Thomas who trails the pack with just 1%.
Unlike previous selections which used an electoral college, Labour will select its 2016 candidate via a primary in which party members and registered supporters will each have a single vote.
The election will use the AV system and require the successful candidate to win the backing of 50% of the selectorate, meaning that the contest is likely to be decided on second preference votes.
Last month YouGov, which unlike the LabourList survey uses a weighted sample for greater accuracy, suggested there was just 3% between Jowell and Khan.
According to that poll, which was carried out in early June, the former Olympics minister enjoyed the backing of 23% of respondents compared to Khan’s 20%. Lammy and Abbott tied for third place with 9% each.
Labour will announce its candidate in mid-September.
