The Greens' advance in the polls is welcome because it shows the clear mood for radical change in the UK. But, as Mark L Thomas argues, there are limits to the project the party presents.
One of the most interesting and optimistic developments in British politics is the sudden growth in popularity of the Green Party. Last month the Greens announced that the combined membership of the Green Party of England and Wales and the Scottish Greens, at just under 45,000, had surpassed both the Lib Dems and Ukip. In the 2010 general election the Greens got an average of around 1.8 percent; last year they began to move towards 5 percent in opinion polls. In some recent polls they have hit double figures. That suggests that up to 2 million people are considering voting Green.
