Latvian Prime Minister Valdis Dombrovskis has signed a formal request applying for eurozone membership, a spokesman for the government in Riga said on Monday.
The application would be handed over to EU Monetary Affairs Commissioner Olli Rehn on Tuesday, the spokesman said. Latvia is seeking entry into the eurozone by January 1, 2014.
The move has been widely expected because the country's basic economic figures - including public debt levels, the budget deficit and the national inflation rate - are all better than required by the European Central Bank (ECB) for membership.
Latvians, who only regained independence after Soviet occupation in 1990, are reluctant, however, to give up their national currency, introduced in 1993. Recent opinion polls showed that two-thirds of the population was against swapping their Lats and santims for the euro.
Latvia would become the second of four Baltic states in the eurozone, after Estonia joined in 2011. It is expected that the ECB will decide on the request in June.
