The ruling bloc tabled the proposal after the parliament on Tuesday upheld President Dalia Grybauskaitė' veto of amendments lowering the yes-vote threshold for a dual citizenship referendum.

Under the new draft amendments to the Law on Referendum, a decision on amending an article of Chapter 1 and Chapter 14 is deemed as adopted if at least two-fifths of all citizens having the right of vote say "yes" in a referendum.

Currently, approval from more than a half of eligible citizens is needed to amend an article of the two chapters, which have a higher level of protection.

Around 2.5 million Lithuanian citizens have the right to vote.
