Former President Chun Doo-hwan Wednesday resigned all his public and political posts to accept responsibility for his brother's role in a massive corruption scandal.

Chun, looking tired and strained, told a news conference he was resigning as chairman of the Advisory Council of State Elders and as honorary president of the governing Democratic Justice Party.

The former president said he was giving up the offices because he failed to prevent his brother's embezzling a fortune in cash, land and stocks through government contacts.
