"I have decided to renounce my functions of foreign minister and I wish success to those who will take part in the government during this period of transition," Morjane was quoted as saying in a written statement.
US-educated Morjane was discredited because of his family links to ousted president Zine El Abidine Ben Ali and has been a leading member of the Constitutional Democratic Rally party, which has dominated Tunisia for decades.
He was one of the eight ministers including Prime Minister Mohammed Ghannouchi from Ben Ali`s last government who stayed on in the new interim government after Ben Ali resigned and fled to Saudi Arabia on January 14.
Morjane reportedly said his resignation was "in the interests of Tunisia and in support of the actions of the national unity government in leading the country to a stable future and so that the popular revolution can bear fruit."
