Prosecutors are unlikely to establish a tax-evasion case against Koichi Kato, a former Liberal Democratic Party power broker, because they don't believe he had any malicious intent, sources close to the case said Thursday.

Kato, a former LDP secretary general, has told tax authorities he will revise his income statements to say he used nearly 100 million yen he received from his political-fund management body for personal purposes -- not as tax-free political funds, the sources said.

He received the funds over four years through 2001.
