The largest "Fringe" challenge in this years general election comes from the Green Party. Over at Phil BC's All that is Solid blog there is a list of no less than 556 candidates from the combined Green Parties of England, Scotland, Wales and Northern Ireland.
They are currently on around 4% in the polls and did get one MP at the last election in the form of Caroline Lucas (Brighton & Hove). Not all has been well in Brighton though as the Greens control the local authority and have not only been in conflict with local government trade unions but have had a lot of very public in-fighting.
Trying to "ban" the bacon sarnie in council canteens on a Friday (as part of a "meat-free programme) did not go down well.....
Of more concern perhaps is Natalie Bennett's view that it should not be illegal to belong to a terrorist organisation and her desire to disband the armed forces.
Here is the Greens leader in her own words courtesy of the Daily Telegraph. Make of it what you will.
