I personally have no burning desire to stop Mr Palmer in his tracks, but Dave, if you want to get a result concentrate on Southampton and start lobbying. You can't stop the ship from being built but, in the unlikely event that the project does get under way, if you want to keep it out of Soton then write to your local MP and Councillor and encourage others to do the same. Petitions can be legally ignored; letters from constituents to elected representatives of government cannot - they are obliged to respond to each one, and if those letters arrive in numbers sufficient to represent a significant body of opinion (which you say exists) then they should feel obliged to raise the matter in Council or even in Parliament. Publicise your need for support by making contact with local newspapers and radio stations and offer to express your concerns and to debate the issue with those who have different views - the Media are always interested in controversial issues. Get a team together to spread the load, and stir things up where it counts. Signing a petition might make you feel better as you said, but starting an organised campaign might actually achieve something.
