Not sure how the parties on Sunday ended up with their allocated seats? 
Luxembourg is divided into four electoral districts: Centre, South, North and East. To calculate how many seats each party won in these districts, Luxembourg uses the so-called D’Hondt method. This has been criticised for making it harder for smaller parties to get a seat, and even bigger gains and losses don’t change the status quo. Click here to find out more about election arithmetic.

Grand Duke Henri on Monday will meet with Prime Minister Xavier Bettel, followed by the President of the Chamber of Deputies, Fernand Etgen, and the President of the Council of State, Christophe Schiltz. The Grand Duke will then meet with representatives of the parties voted into parliament. It is up to Luxembourg’s monarch to appoint a so-called “formateur”, who will lead coalition talks and usually becomes the country’s next prime minister.

Nommern around 11pm on Sunday evening was the last commune to post election results, confirming the last projections. That leaves the current DP-LSAP-déi Gréng government short of a majority.
In the Centre, the CSV was the strongest party with seven out of 21 seats, followed by the DP at six seats, the LSAP with three mandates, déi Gréng with two seats and déi Lénk, the ADR and the Pirate Party with one seat each.

The last projection before final results are called in Sunday’s election sees the current coalition lose its majority in parliament at just 29 out of 60 seats in parliament, down from 31.
The biggest loser of the night would be déi Gréng, receiving four seats, down from nine after the last election in 2018. The LSAP would gain one seat to reach 11 mandates, with the DP adding two seats to reach 14. The CSV would keep its 21 seats in parliament. Déi Lénk would stay at two seats. The ADR and the Pirates are projected to win one seat each to reach five and three mandates, respectively.
