Liberal Democratic Party leader Shinzo Abe has indicated he will move swiftly on a large supplementary budget for the current fiscal year if the LDP regains power in the Dec. 16 election and he becomes prime minister.

"The supplementary budget should be large-scale," Abe said Thursday. "It will be compiled to firmly support the economy."

On the budget's size, the former prime minister said he would consider filling the demand-supply gap, indicating it would be in the scale of ¥10 trillion.
