The Liberal Democratic Party, set to form a new government, decided Thursday to put together a pump-priming package by Jan. 11 to keep the lethargic economy afloat, party lawmakers said Thursday.

Based on the package, the new government, to be led by LDP leader Shinzo Abe after the party's landslide victory in Sunday's Lower House election, will decide on a supplementary budget on Jan. 15 for its submission to the Diet in January, they said.

"We'll work out the budget by giving up yearend and New Year's holidays," LDP Policy Research Council Chairman Akira Amari told reporters after a meeting of party executives where the decision was made.
