Not bothering to vote.
Thought for the day - in local and general elections, the turn out is generally quite poor and not really representative of the nation. In some countries it is illegal not to vote. I don't think that should happen here but my solution would be the opposite. If you don't vote, your vote will be counted as a vote for the current party. So, if you support the conservatives, or have no interest in politics, or can't be arsed to vote, then don't. If you don't like the way the country is run then go and vote. It amazes me how many people moan about the government, local councils etc when they haven't done anything about it.
