Naseer al-Chaderchi is the leader of the National Democratic Party (NDP) and has a seat on the Iraqi Governing Council. He is the son of the leading democracy advocate Kamel al-Chaderchi who led the NDP in the 1950s and opposed the British-backed monarchy.
Mr Chaderchi, a Sunni, stayed in Iraq under the Baathists. He lives in Baghdad and works as a lawyer, businessman and farm-owner.
Observers say he may be gaining support from the fact that Iraqis are familiar with his family's name and his father's role in pre-Baathist Iraq.
