While no official information about the context of the meeting is available, it is expected that the talks will focus on the recovery package after the Covid-19 pandemic and Slovenia's presidency of the EU Council in the second half of 2021.

There are some issues in the relationship between Slovenia and Brussels, including the European Commission's legal action against Slovenia for alleged violation of inviolability of the ECB archives in the seizure of 2013 bank bailout documents, and the recent replacement of the director of the National Statistics Office.

Janša has addressed a letter to von der Leyen to examine the possibility for the Commission to abandon the action against Slovenia, which the Commission would not comment on, but available information indicates von der Leyen has not yet responded to the letter.

Nor has the Commission received yet Janša's answer to Economy Commissioner Paolo Gentiloni, who asked for explanations on the replacement of the statistics head.

Vera Jourova, the Commission vice-president responsible for values and transparency, said in late April she had contacted the Slovenian authorities in relation to media freedom.

While in Brussels, Janša is also expected to meet European Council President Charles Michel, and NATO Secretary General Jens Stoltenberg, according to unofficial sources.

Those have indicated that Foreign Minister Anže Logar is also due in Brussels this week.
