A top Liberal Democratic Party lawmaker said Sunday it is premature to quickly decide whether to compile a supplementary budget for fiscal 2002.

"It is too early to discuss the matter. It's inappropriate (to decide it now)," LDP Secretary General Taku Yamasaki told a TV program that aired in the morning.

Yamasaki was referring to growing calls from some lawmakers in Prime Minister Junichiro Koizumi's tripartite ruling coalition for an early formulation of an extra budget to shore up the economy amid tumbling stocks.
