When Ingvar Carlsson resigned as Prime Minister in 1996, it took only a few days before Göran Persson could be formally elected.

Today - when Stefan Löfven resigns - the situation appears to be much more complicated.

Background: The January agreement was broken in connection with the government crisis this summer.

This means that the government base that Magdalena Andersson hopes will support her only collects 175 seats, ie the smallest possible margin.

In addition to the government parties, this also includes the Center Party and the Left Party.

The problem for Magdalena Andersson, however, is that neither C nor V have so far announced whether they will actually release her.

To become prime minister, the no votes are the most important.

As long as 175 or more members of the Riksdag do not vote no, she will become Prime Minister.

Monday or Tuesday

The announcement from Stefan Löfven on Sunday that he will submit his resignation application to the Speaker at the beginning of the week should be interpreted as meaning that he will do so either on Monday or Tuesday.

Thereafter, the Speaker initiates a first round of Speakers with all party leaders to investigate whether there is sufficient support for Magdalena Andersson or any other party leader.

The process can go fast if it quickly turns out that there is support for Andersson.

Then the Speaker can immediately place such a proposal on the Riksdag's table.

It shall be tabled at two meetings for two days.

A prime ministerial vote could then be held on Thursday or Friday.

But only after a shift council with the king is Magdalena Andersson formally prime minister.

Such a council can be held early the following week, on Monday or Tuesday.

Can be a thriller

This is of course a scenario Magdalena Andersson dreams of.

But it can also take much longer.

The possible obstacles are obvious.

In the worst case, this could develop into a thriller for her.

The Center Party has demanded strengthened ownership for forest owners and relaxed beach protection in sparsely populated areas to release Andersson.

On both points, the Green Party, the other governing party, has taken a stand.

Negotiations between the government and the Center Party have been ongoing since last summer on these issues.

With regard to the forest, the parties agree in principle, with regard to beach protection, no agreement has yet been reached.

Negotiations are still ongoing.

The Center Party's support for the new Prime Minister thus still hangs in the air as an unanswered question.

Here, a settlement must be in place before Magdalena Andersson wants to go up in a prime ministerial vote.

Politics on the left

On the other hand, it rumbles from the Left Party.

Party leader Nooshi Dadgostar demanded in a recent interview that the government's entire policy be shifted to the left in order for the Left Party to release Magdalena Andersson.

Dadgostar also wants the government to postpone the changes to the Employment Protection Act (read) until after the election.

In addition, the Left Party now also demands influence over the issues concerning forests and beaches.

However, it is difficult to determine how ultimate these requirements are.

Nooshi Dadgostar has also said that the most important thing is that the Left Party receives recognition as part of the government base, which seems simpler.

The Left Party's answers to these questions may determine Magdalena Andersson's fate as Prime Minister or at least delay the process considerably.

Do not forget that after the 2018 election, the parties spent several months negotiating an agreement to release Stefan Löfven as prime minister.
