How the leadership votes were allocated

This is how voting in the Labour leadership contest unfolded.

Under the complex electoral college system employed by the party, voting power is divided equally between three sections: MPs and MEPs, affiliated organisations including trade unions and ordinary party members.

If no single candidate secures 50% or more of the first round vote, the last-placed hopeful is eliminated and the second preferences of their backers are redistributed.

That process continues until one reaches the required threshold - potentially ending in a direct head-to-head between two candidates.

The scores are listed here as a percentage of overall vote share and how it was made up by each section (in the order MPs and MEPs/ party members/affiliated organisations):

First Round:

Diane Abbott 7.42 ( 0.877, 2.447, 4.093)

Ed Balls: 11.79 ( 5.013, 3.371, 3.411)

Andy Burnham 8.68 ( 3.008, 2.849, 2.825)

David Miliband 37.78 (13.910, 14.688, 9.182)

Ed Miliband 34.33 (10.526, 9.978, 13.821)

As no-one exceeded 50%, Diane Abbott was eliminated and the second preferences redistributed.

Second round:

Ed Balls 13.3 ( 5.171, 4.224, 3.829)

Andy Burnham 10.41 ( 3.03, 3.298, 4.078)

David Miliband 38.89 (14.015, 15.076, 9.799)

Ed Miliband 37.47 (11.111, 11.13, 15.231)

As no-one exceeded 50%, Andy Burnham was eliminated and his second preferences redistributed.

Third round:

Ed Balls 16.02 ( 5.429, 4.823, 5.76)

David Miliband 42.72 (15.783, 16.076, 10.861)

Ed Miliband 41.26 (12.121, 12.424, 16.706)

As no-one exceeded 50%, Ed Balls was eliminated and his second preferences redistributed.

Fourth round:

David Miliband 49.35 (17.812, 18.135, 13.40)

Ed Miliband 50.65 (15.522, 15.198, 19.934)

As he exceeded the 50% threshold, Ed Miliband was elected leader.
