Senior lawyer H S Phoolka on Tuesday said he has decided to join the Aam Aadmi Party.
"To ensure good governance and freedom from moral and economic corruption, social activists have come together to form this political party. I have decided to join it," he said in a statement.
"I want to be an active part of this social revolution -- thus joining AAP is my natural choice," he said.
Phoolka has been taking up the causes of victims of anti-Sikh riots in Delhi in 1984.
