For the first time in a European Parliament election, you can vote in a primary.
All the Green Parties in Europe have come together to give you a chance to vote for the leading candidates. The winner will be the leader of the Green group in the Parliament and a possible contender for the Greens/EFA nominee for President of the European Commission.
There are 4 candidates in the primary. Each candidate has the support of 5 national Green Parties.
You can read more about the primary on the European Green Party site.
There will be hustings in London on 18 January 2014.
