Many takes on the local elections in Denmark.
Important to note a mixed picture imho:
📉 Social democrats lose (5,2%), social / green parties win (3,7%)
Liberal and conservatives lose (5,8%), right wing parties win (6,4%)📈
Social democrats have biggest loss, also in terms of mayors.
But mixed 🖼️📊

I don't know how much we can learn about immigration policy in other countries from a local election in Denmark that had nothing to do with immigration.
In a survey conducted by Epinion (n = 102.897) integration was the second least important topic (out of 13) for voters in this election.

Interference in election campaigns by foreign actors is a deliberate attempt at destabilizing. It is worrying but also important for democracies to build up resilience against this.
