Juras Pozela was the youngest member of the Social Democratic-led Cabinet. He died Sunday after having been hospitalised for two months in intensive care with acute pancreatitis.
His family and the Social Democratic party made the announcement today.
Grieving family members met with ruling Social Democratic party leaders to discuss plans for a funeral later this week, just before the second round of parliamentary elections. Pozela was a re-elected on October 9 in the first round of the elections.
It wasn't immediately clear who would take his seats in the Parliament and Cabinet.
