According to the German newspaper FAZ, a recount is possible.
What is the prince saying about this?
I can't answer that question, but the election was officially certified and FBP conceded it to VU.
Btw, as one person has multiple votes, it might actually be the case that the whole election was decided by
one ballot. 15 901 people voted and 201 770 votes were cast, while the vote difference between VU and FBP was 23. So the average Liechtensteinian (?) cast 13 votes, and if one single person changed 12 votes from VU to FBP candidates, FBP would've won by a single vote.
Marianette Miller-Meeks' win is a landslide compared to this.
