Campaigner sets her sights on Samsung Lees' huge IPO windfall

As a student, Park Young-sun always enjoyed standing up to the big boys.

"She was the unofficial head of all the girls and would confront boys that bullied or played pranks on them," said Bruce Lee, a fund manager who first met the three-term opposition lawmaker almost five decades ago when they were seven-year-olds in elementary school in Seoul.

Park has shifted her sights from schoolyard bullies to business titans and her latest target is as powerful as they come: the family behind the nation's biggest conglomerate or chaebol, Samsung Group. She says they should pay back profits from a 1999 deal later ruled by courts to be illegal - money she says the family may use to fund the transfer of assets to the children of Samsung patriarch Lee Kun-hee. Lee remains hospitalized following a heart attack.
