Taiwan leader's son-in-law jailed

Chao Chien-min was found guilty of using inside information to profit from buying shares in a property company.

Chao, who is married to President Chen's daughter, is expected to appeal.

The high-profile case is the latest setback for the president, whose wife is also on trial for embezzlement and forgery in a separate proceeding.

The first lady denies illegally using state funds for personal expenses.

Her husband faces similar accusations but is protected from prosecution by presidential immunity.

He has promised to resign if she is found guilty.
