"The president has vetoed the Law on Seimas Elections and is sending it back for deliberation," Antanas Manstavicius, a presidential advisor, told BNS.

Currently, political parties need to receive at least 5 percent of the national vote in the multi-member constituency to get seats in the parliament and coalitions have to clear a 7 percent threshold.

The president earlier backed a 4 percent threshold for parties and 6 percent for party coalitions.

The Seimas passed the new law on December 10, mostly by votes of the ruling coalition parties.
