The jailed de facto leader of the giant Samsung group walks free on parole Friday, as proteters gather outside the detention centre. This marks the latest instance of South Korea's long tradition of freeing business leaders imprisoned for corruption or tax evasion on economic grounds. Lee Jae-yong -- the 202nd richest person in the world according to Forbes, with a net worth of $11.4 billion -- was serving a two-and-a-half year prison sentence for bribery, embezzlement and other offences in connection with the corruption scandal that brought down ex-South Korean president Park Geun-hye.
