Latvia's Prime Minister Valdis Dombrovskis speaks to press outside the collapsed supermarket shortly after the disaster in Riga, Latvia. Riga, Latvia: Latvian Prime Minister Valdis Dombrovskis has resigned after the collapse last week of a supermarket roof in the capital Riga that killed more than 50 people, his spokesman said on Wednesday. The resignation throws into political turmoil a Baltic state that is due to join the euro zone in January and is seen as an example of fiscal prudence and economic recovery after a deep financial crisis in 2008. I announce resigning from the post of prime minister, taking political responsibility for ... the tragedy "I announce resigning from the post of Prime Minister, taking political responsibility for ... the tragedy," Dombrovskis told journalists, according to local news agency BNS. The Prime Minister's spokesman Martins Panke confirmed the resignation. The government had come under criticism after the disaster. Dombrovskis had previously said the collapse had shattered Latvia, a former Soviet republic which joined the European Union nearly a decade ago. Latvian President Andris Berzins had called the disaster "murder." The cause of the collapse remains unknown, although police have opened a criminal investigation focusing on the construction of the building. Local media said workers had been building a roof garden on the supermarket, a single-storey building located about a 30-minute drive from the city centre.
