The Swiss will vote on Sunday on two popular initiatives that could change the lives of pensioners. One initiative calls for a 13th month pension for retirees.

The other calls for the retirement age to be gradually raised from 65 to 66. According to surveys, a majority of those eligible to vote are in favor of the plan - although the lead has recently fallen, so the success of the popular initiative is uncertain. The maximum monthly pension in Switzerland is currently 2,450 Swiss francs (around 2,470 euros) for single people.
