The oath taking ceremony was attended by former prime minister Raja Pervez Ashraf, former speaker of National Assembly Dr Fehmida Mirza, other former ministers and high ranking officials of the Armed Forces of the country.
However, no representative from the PML-N, PML-Q, MQM, PTI and PML-F were in attendance.
Upon his arrival at the Prime Minister House following the oath taking ceremony, Justice (retd) Mir Hazar Khan Khoso was given a guard of honour.
Talking to media after being selected by the ECP as caretaker prime minister of the country on Sunday, Justice (retd) Mir Hazar Khan Khoso rejected a perception that the caretaker set-up was going to stay for more than the stipulated period and asserted that elections would be held on time. Holding fair and transparent elections was his top priority, he added.
He said his cabinet would comprise only 10 to 12 members which could include politicians.
He observed that elections were the only solution to problems faced by the country and said he would soon meet all political leaders.
About the law and order situation, he said it was the responsibility of the provinces and consultations would be held with them on the issue. He said he would quit if he failed to hold the elections on time.
