The government's top priority is economic stabilisation, with the $350 billion economy on a narrow recovery path after getting a last minute $3 billion bailout deal with the International Monetary Fund, averting a sovereign debt default.

Economic reforms implemented so far have led to historic levels of inflation and high interest rates, however. The top challenge for the caretaker government and its successor remains the stabilisation of the economy.

Kakar himself was sworn in on Monday after President Arif Alvi dissolved parliament last week on the advice of outgoing Prime Minister Shehbaz Sharif.

Kakar on Thursday appointed the new cabinet, which was later sworn in by Alvi.

Under Pakistan's constitution, a neutral caretaker government will oversee elections that must be held within 90 days of the dissolution of parliament's lower house, which in this case means early November.

However, the ballot may be delayed as the Election Commission has to draw new boundaries for hundreds of federal and provincial constituencies. After that it will give an election date.

Later on Thursday, the election commission said new constituencies would be finalized by Dec. 14, state television reported.

In the interim cabinet, former central bank chief Shamshad Akhtar was appointed finance minister, and Pakistan's former ambassador to the United States, Jalil Abbas Jilani, was named foreign minister, the new information minister Murtaza Solangi said.

Other names in the cabinet include former provincial minister Sarfaraz Bugti as interior minister and Mishaal Malik, the wife of jailed Kashmiri Leader Yaseen Malik, as Minister for Human Rights.
