What: Signa, has filed for insolvency after failing to raise additional funds.

Why it is important: The company cited a lack of necessary liquidity and severe economic pressure as the reasons for its financial struggles.

Restructuring experts may consider selling Signa's stakes in an effort to generate funds, potentially leading to a new landlord for Selfridges. However, Selfridges confirmed that it continues to operate normally and has the ongoing support of Central Group.
