Another senior GERB official warned Bulgaria could have another election by Christmas if cross-party talks broke down.

Together with GERB they hold 107 seats - 14 short of a parliamentary majority.

Party officials said GERB would look to form a minority government, either alone or with the help of smaller parties.

In a sign of possible trouble ahead, GERB leader Boiko Borisov warned it would be difficult to form a coalition.

The exit polls indicated GERB had won about 33 percent of the vote, twice as many as their main Socialist opponents.
