According to the newspaper, Magdalena Andersson will call a governmental meeting late on Monday where the decision on whether to join Nato will be made, after which the country will send in formal documentation immediately.

Officials at Sweden’s foreign ministry have been drafting the text for several weeks, the paper claims, meaning it is now complete and ready to be submitted. 

The meeting will follow a debate scheduled in Sweden’s Riksdag parliament for 10.30am on Monday morning, which will discuss the conclusions of the Swedish government’s ‘security policy analysis group’, which is due to submit its reassessment of Sweden’s security situation this Friday. The anti-Nato Left and Green parties are unlikely to support the conclusions of the report and the report is not expected to state explicitly whether Sweden should join the alliance or not.

After the debate, Finland’s president, Sauli Niinistö, who is on a state visit to Sweden, will hold a speech in the parliament, with the title “a responsible, strong and stable North”. 

Finland on Thursday kicked off the formal process whereby Sweden and Finland are likely to join Nato, when its president Sauli Niinistö and prime minister Sanna Marin published a joint statement recommending that Finland apply to join “without delay”. 

On Sunday, the ruling committee of Sweden’s ruling Social Democrats will take a decision on whether to back Nato membership for Sweden, thereby reversing the policy of non-alignment it has supported since before Nato was founded. 

The formal shift in the Social Democrats’ position will remove the last hurdle to a Swedish decision in favour of joining Nato. 

Here’s a breakdown of how the day might look: 

• 9am. The day starts at 9am, Swedish time, when the Finnish parliament meets to discuss the decision taken by the government on Sunday. No other parliamentary business is scheduled. According to the Hufvudstadsbladet newspaper the Finnish parliament will also publish the conclusions of its debates in a letter to the government recommending that Finland apply to join Nato.
• 10.30am. A debate is scheduled in Sweden’s parliament, which will discuss the conclusions of the Swedish government’s ‘security policy analysis group’. 
• 12am. Finland’s president, Sauli Niinistö, who is on a state visit to Sweden, will hold a speech in the parliament with the title “a responsible, strong and stable North”. 
• Afternoon: According to Expressen, Sweden’s prime minister, Magdalena Andersson will call a governmental meeting late on Monday, where the decision on whether to join Nato will be made.
• Officials at Sweden’s foreign ministry have been drafting the text of the application for several weeks, the paper claims, meaning it is now complete and ready to be submitted.
