From yesterday's Guardian
I've been reading with interest the recent correspondence on these pages about the kind of Labour party people would like to vote for. As I read through the list of John Walton's initial policy proposals (Suggestions for a Labour manifesto,
 14 August), it struck me that they all sounded very familiar. And 
that's for the very good reason that, almost without exception, they are
 long-standing Green party
 policies. Whether it's repealing the coalition's disastrous NHS 
legislation, bringing rail back into public ownership (the subject of my
 current private member's bill), abandoning PFI and ending the 
privatising of public services, or scrapping Trident and ending 
fracking, these are all policies the Greens have long espoused.
Although
 imitation may be the sincerest form of flattery, I can't help thinking 
that the best way to see these policies realised would be for the people
 who support them to vote for the party that is already signed up to 
them.
Over a million people voted for the Green party in the last 
European elections (the last time the UK had a nationwide vote under a 
proportional system), and a recent YouGov poll for the Electoral Reform 
Society put us at 12%, ahead of the Lib Dems, and on course to win four 
more seats at the Euro elections next year, taking our tally to six.
We
 don't need a new radical and progressive political party: we need a 
fairer electoral system to allow the one we've got, the Green party, to 
break through in the general election, and give louder voice to these 
views. Under proportional representation, there would be no need for 
"splits on the left", as some of your correspondents feared – 
progressive parties could work together in the best interests of 
everyone who wants to see a socially just and environmentally 
sustainable future.
