Others argued a blank vote because it would improve possibilities for a future in-depth constitutional reform.

The number of blank and invalid votes was much higher in big cities, especially Copenhagen.

In the end, the House of Freedom chose to cast a blank vote.

The Delfzijl turnout with the blank votes included was 61.1%.

"Those blank votes go beyond logical explanation," he said.

If however they are forced to go to the polling place, they can still use a blank or invalid vote.

That resulted in a blank vote, one of perhaps hundreds accidentally cast across the city.

One blank vote was cast in the second and final round.

This was adopted by the Committee almost unanimously, with only one member casting a blank vote.

Although the results saw 55.67% vote in favour of setting the voting age at 18, when the blank votes were included, this dropped to 46.71%.
