LABOUR rightwingers warning of a possible court challenge to the leadership vote are fuelling the row over party membership because Jeremy Corbyn “is setting the political agenda,” his campaign team said last night.

Andy Burnham’s campaign manager Michael Dugher suggested yesterday that the outcome of Labour’s leadership election could be subject to “legal challenge” due to the party’s inability to properly investigate newly registered voters.

His intervention came as Blairite candidate Liz Kendall denied an allegation that her campaign had gathered information to assist the “purge” of party members.
