[3] The elections resulted in a victory for the "red bloc", comprising parties that supported the Social Democrats' leader Mette Frederiksen as candidate for prime minister.

On 6 June, incumbent Prime Minister Lars Løkke Rasmussen of the centre-right liberal Venstre party tendered his resignation, and Frederiksen was tasked with forming a new government.

Riskær Pedersen found a way to circumvent a 7-day "thinking period" between a voter noting their support for a party and then confirming their signature in the online collection system.

[18] Following this, all political parties in the Folketing agreed to close the loophole and build a new portal for declarations, expected to be available in the end 2020.

[19] In April 2019, following unrest at Nørrebro caused by demonstrations by anti-Islamist politician Rasmus Paludan, his party Hard Line managed to collect the required signatures.

[30] In the previous elections, Aleqa Hammond won a seat as a Siumut candidate, but was expelled from the party in August 2016 following a case about misuse of funds from the Folketing.

[46] On 26 June 2018, The Alternative, which traditionally is regarded as belonging to the "red bloc", stated that they no longer would support Mette Frederiksen as candidate to become prime minister.

[48] The move was met with criticism, as Elbæk's chances are very slim, and it could risk keeping Lars Løkke Rasmussen as prime minister.

[52] While Venstre, Liberal Alliance and the Conservatives said that Hard Line should not be considered as part of the "blue bloc" when committee seats are distributed, the Danish People's Party were open to that possibility.

From 2010 to 2013 he had been stalking a 24-year-old man he met while studying Latin, and in 2015 he was sentenced a fine for offending a police officer who handled the case.

[64] On 16 May, Løkke Rasmussen published a book, in which he was open to a possible coalition government between the Social Democratic Party and Venstre (Danish: SV-regering).

[70] The idea of an SV-government were immediately rejected by Frederiksen, who said that the political differences are too big, and reiterated that the Social Democrats wished to form a single-party government after the election.

[73] On the other hand, the Social Liberals and the Danish People's Party welcomed the announcement, while the Red–Green Alliance refused to support such a government.

[75] On 4 June, the day before the election, Løkke Rasmussen gave up on his plans to form a centre-right government, saying it was no longer "realistic".

He instead made it his first priority to create a government across the political middle, in order to keep the right- and left wing away from power.

Pape Poulsen rejected taking part in such a government, questioning what the political foundation should be while Samuelsen said that Løkke Rasmussen had "let down" the civic-liberal Denmark.

[77] Kristian Thulesen Dahl, leader of the Danish People's Party, said that it was paramount to them to take part in such a cooperation, so the Social Liberals and The Alternative did not influence it.

[80] Overall the election was a win for the "red bloc" – the parties that supported Mette Frederiksen, leader of the Social Democrats, as prime minister.

[81] The Social Democrats defended their position as the largest party, and won an additional seat despite a slightly reduced voter share.

Leader Kristian Thulesen Dahl speculated that the bad result was due to an extraordinary good election in 2015, and that some voters felt they could "gain [their] policy elsewhere".

[94][95] On 19 June, the Social Democrats, the Socialist People's Party and the Red–Green Alliance announced an agreement on global warming, committing to reduce Denmark's emission of CO2 by 70% in 2030.

[96] On 25 June, the four parties announced that they had reached an agreement, allowing Frederiksen to become prime minister as leader of a single-party Social Democratic government.

[98] Frederiksen decided not to formulate a government basis white paper, as is otherwise tradition, saying that it was sufficient with the 18-page "political understanding" she had agreed with her parliamentary support.
