Iranian reformist MP Rassul Mehrparvar (2nd R), and his son Mobin, 10, participate in a sit-in at the parliament in Tehran, 13 January 2004. Disgruntled reformist MPs, 83 of whom have been barred from standing for re-election, kept up their sit-in at the Iranian parliament, or Majlis, for the third day and said they were willing to stay put for weeks, unless their rivals backed down on a move to bar reformers from next month's elections.
