The son of Iran's toppled shah has a new job as spokesman for a nascent movement to press for free and fair elections in his homeland.

Reza Pahlavi said Thursday that his Paris-based collective, the Iranian National Council, brings together tens of thousands of pro-democracy people from both inside and outside Iran.

He said the council "is calling for a major boycott" of Iran's June presidential vote but that "is not enough." He also said a civil disobedience campaign should follow if elections aren't free and fair.

Pahlavi says "we are challenging the regime."

Iran's 2009 presidential vote led to major protests that were brutally repressed.
