Mats Knutson, SVT's internal political commentator is not surprised by Ulla Andersson's message.

- Ulla Andersson has not made a secret that she likes best in the second phase. She doesn't like to stand first and that she prefers to work on politics. She has previously been burnt out due to stress and now does not want to take the step into the front line, because of this. But if she had agreed to become the new leader of the left party, she certainly would have - she has great support, says Mats Knutson.

- In all likelihood, Nooshi Dadgostar will become the new party leader of the Left Party. She has been selected as a favorite and now she is also supported by Ulla Andersson, which means that she goes first with other possible candidates, he continues.

However, Mats Knutson believes that this type of process is difficult to predict.

- We do not know what will happen. The congress is not until May, things can happen that are difficult to predict, but with Ulla Andersson's message, Nooshi Dadgostar is an obvious candidate.

Hard to succeed Jonas Sjöstedt

What does this mean for the party?

- Firstly, it is difficult to succeed a popular party leader like Jonas Sjöstedt, who has such great confidence. Whoever succeeds may end up in a bad spiral. In any case, initially. Nooshi Dadgostar will experience this when she takes office.

- The Left Party has had a big advantage, Jonas Sjöstedt is one of those voters who have the greatest confidence, it pulls a party forward. For a new leader who does not have this, it will be an uphill climb. They risk reversing opinion and losing influence, says Mats Knutson

- But it is impossible to know what a change of party leader means for a party in the long term, he continues.
