As far as direct presidential elections are concerned, the basic distinction is between plurality rule and majority runoff. Under plurality rule, the candidate with the most votes is elected. Under majority run-off, a majority of votes (that is more than 50%) is required for election in the first round. If no candidate secures a majority, then the (usually top two) candidates compete in a run-off election. Worldwide there is a clear tendency towards majority run-off systems in order to avoid the “plurality trap”, by which a candidate who is strongly opposed by a majority of voters can win the presidency. In accordance with the worldwide tendency, majority run-off is common in direct presidential elections in CoE member states. Only in a few countries, such as Azerbaijan, Bosnia and Herzegovina and Iceland, is the president elected by plurality. Significantly, in Iceland concerns have been expressed that, in the case of a large number of candidates, the president could be elected by only a minority of voters.
