Sudan's newly-appointed First Vice President Bakri Hassan Saleh, Second Vice President Osman Mohamed Yousif Kibir and Prime Minister Mutaz Mussa were sworn in on Monday before Sudanese President Omar al-Bashir.

"These changes came to reaffirm a real will to achieve a positive change in the economy, society and politics," Kibir told reporters following the swearing-in ceremony.

"We are fully aware of the requirements of the current phase which come within the framework of the national economic reform program," he added.

The Leadership Office of Sudan's ruling National Congress Party (NCP) on Sunday approved the decision of al-Bashir to dissolve the national unity government and appoint a new prime minister to tackle the country's growing economic crisis.

The decision came after an earlier meeting held by the NCP Leadership Office, chaired by al-Bashir, to discuss changes to the government and the proposed candidates of the new cabinet members.

The meeting appointed Saleh, who had served as both prime minister and first vice president, as the first vice president only, and Mussa, former Minister of Irrigation and Electricity, as prime minister.

Meanwhile, Kibir was appointed as the second vice president to replace Hassabo Mohamed Abdul-Rahman.

Sudan has been suffering from an economic crisis caused by the shortage of liquidity and the devaluation of its national currency.
