Adrian Ramsay to stand for re-election as Greens co-leader with Ellie Chowns

Exclusive: Waveney Valley MP and North Hereforshire MP likely to go up against party's deputy leader Zack Polanski

• Green party must choose again between election-focused or activist leaders

Adrian Ramsay is to stand as Greens co-leader with another of the party's MPs, Ellie Chowns, amid what the duo describe as an unprecedented fracturing of political allegiances that meant it was vital to have leaders in Westminster with a proven record of winning.

Ramsay has already been co-leader for four years, alongside Carla Denyer, who with Ramsay, Chowns and Sian Berry were elected to parliament last year in the party's greatest electoral triumph.
