The former chief minister of Tamil Nadu J Jayalalithaa has been cleared of all charges of corruption by an Indian court on Monday.

"Truth and justice have prevailed," said Ms Jayalalithaa in a statement after the court decision. "I am immensely satisfied, the verdict has paved the way for me to emerge as tested pure gold," she added.

Ms Jayalalithaa maintained that there was no wrongdoing and that the charges were “foisted (on me) by political enemies.”

The ruling now clears the way for her to return as chief minister.
