In the EU elections the Greens returned three MEP's and 1.2 million votes (7.8% of the total)- more then the Lib Dems.
In the council elections the Greens were returning councillors in constituencies in which they have never done so before, and becoming the official opposition in Liverpool (where UKIP gained no council seats), Solihull, Islington, Lewisham and Norwich. They also increased their gains in Bristol, and gained councillors for the first time in Newcastle-Under-Lyme, Epping Forest, Babergh and the Wirral.
And they have an MP.
It is undemocratic to include Farage in these debates and not Natalie Bennett.
Possibly. I suppose their rationale is that with limited time available, five might be too much. Who knows. I don't suppose the events will change much either way. Most people already know how they'll vote don't they?
