There is no problem with single round plurality systems as in Britain. The person who receives the most votes is elected with no minimum condition. In practice, people are rarely elected with fewer than 35% of the votes cast. Since the abstention rate may be as much as 40% (38.5% in the United Kingdom in 2005), this constitutes barely more than 20% of the registered voters in that constituency, which is not very representative but still more votes than any other candidate has received, thus justifying that person's election. Nevertheless, the temptation to introduce a minimum participation threshold, as certain countries do for referendums, must be avoided, since this could result in a parliament that was poorly representative, because it was incomplete.
