Here's what has happened in Sweden.
People have been caught handing out money and pre filled ballots and driving people to polling station in suspected election fraud.
A man from Somalia who got Swedish citizenship 7 months ago and has ties to the Somalian government was elected to parliament.
Another man has also been elected to the municipal council.
Both of them for the Left party.
Now there is a possibility there could be a rerun of the election locally.
If this happens, it would be the first time there has been a rerun of election to parliament in Sweden.
We are looking at an unprecedented situation.
And if there is a rerun, there is a very real possibility that the right could flip enough seats to get a majority in parliament and win the election.
