Sept 28 (Reuters) - Slovakia's Prime Minister Eduard Heger said that soaring electricity costs had left the country's economy at risk of "collapse", the Financial Times reported on Wednesday.

Heger said that the increase in prices following Russia's invasion of Ukraine would "kill" the country's economy unless it received billions of euros of support from Brussels, FT quoted Heger as saying in an interview.

Heger also warned he would be forced to nationalise the country's power supplies if this was not forthcoming, the report added. (Reporting by Anirudh Saligrama in Bengaluru; Editing by Muralikumar Anantharaman)
