In recent months, Labour figures have become increasingly concerned by the electoral threat posed by the Greens. The growth of the party, which has polled as high as 8 per cent in some polls and has increased its membership by 45 per cent this year to 26,000, is in danger of creating a split on the left to match that on the right.
Alongside their traditional environmentalist platform, the Greens are promoting policies with strong appeal to Labour voters such as a £10 minimum wage by 2020, a wealth tax on the top 1 per cent and the renationalisation of the railways, branding themselves as “the only anti-austerity party”. In close contests with the Tories and the Lib Dems, most notably in London, the level of the Green vote could make the difference between winning and losing.
