A financial working group of the Liberal Democratic Party adopted a resolution Friday urging the Bank of Japan to set a clear inflation target to combat deflation.

The group, headed by party heavyweight Hideyuki Aizawa, said the central bank should target a rise of up to 2 percent in the consumer price index within two years.

The latest government data show that the index in Tokyo dropped 1.4 percent in November from a year earlier for the 27th consecutive monthly decline.
