Jordan's King Abdullah has named a technocrat prime minister after the current cabinet resigned following parliamentary elections, officials say.
Mr Dahabi's brother is head of the general intelligence department
Nader al-Dahabi, a Western-educated former transport minister and air force commander, has reportedly been given the task of boosting the economy.
Mr Dahabi succeeds Maaruf al-Bakhit, who had been prime minister since 2005.
The elections on Tuesday strengthened the position of tribal leaders and other pro-government candidates.
The opposition Islamic Action Front won only six seats compared with the 17 it gained in the 2003 election, prompting its leaders to accuse the Jordanian authorities of widespread fraud.
The interior minister has denied any wrongdoing, saying the government had conducted "impartial and fair" elections.
King Abdullah officially designated Mr Dahabi to form a new cabinet on Thursday afternoon shortly after Mr Bakhit submitted his government's resignation, senior officials said.
"The new government will be announced Sunday and its members will be sworn in before the king," one official told the AFP news agency.
