You can if you want to and can find the requisite people to nominate you and put up the deposit. Hundreds do, from local campaigners to David Icke, though with rare exceptions like Martin Bell the party system and the huge difficulty of getting your message across to 80,000 electors usually works against you.If you disagree with a governmental decision do you stand for election as an MP?
But the Trust is much more democratic than Parliament and you don't even have to risk losing a deposit, assuming you have invested £25 a year or £2 a month to become a Member. You can also put forward resolutions to the Trust AGM and have them voted on and become policy. It works, I have done it myself.
