Philippa is effectively Regent during King Eric's periods of absence abroad.

In Sweden, where she spends a lot of her time, she appears to have been de facto ruler even when the King was in residence.

Eric evidently has great trust in Philippa.

Both medieval and modern authors give a favorable account of her rule.

It is even said that in certain matters she was more efficient than her husband; scholars have largely accepted this judgment of the Queen without going into detail.

Philippa in 1422 presides over the Swedish council in order to solve a dispute between Swedish noble factions.
