Prime Minister Yoshiro Mori on Wednesday formally ordered the government to draft a 10 trillion yen economic stimulus package that will include an extra budget of nearly 4 trillion yen for the current fiscal year.

The 11th pump-priming effort since 1992 is expected to be compiled around Oct. 20 and submitted to the Diet in November, a senior government official said.

Mori gave the instruction at a special Cabinet meeting held immediately after a government-ruling coalition budget conference.
