The Government of Estonia (Estonian: Vabariigi Valitsus) or the executive branch is formed by the Prime Minister of Estonia, nominated by the president and approved by the parliament. The government exercises executive power pursuant to the Constitution of Estonia and the laws of the Republic of Estonia and consists of twelve ministers, including the Prime Minister. The Prime Minister also has the right to appoint other ministers and assign them a subject to deal with. These are ministers without portfolio — they don't have a ministry to control.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who has the ability to assign other ministers?
Ah, so.. The Prime Minister

Around 746, Abu Muslim assumed leadership of the Hashimiyya in Khurasan. In 747, he successfully initiated an open revolt against Umayyad rule, which was carried out under the sign of the black flag. He soon established control of Khurasan, expelling its Umayyad governor, Nasr ibn Sayyar, and dispatched an army westwards. Kufa fell to the Hashimiyya in 749, the last Umayyad stronghold in Iraq, Wasit, was placed under siege, and in November of the same year Abu al-Abbas was recognized as the new caliph in the mosque at Kufa.[citation needed] At this point Marwan mobilized his troops from Harran and advanced toward Iraq. In January 750 the two forces met in the Battle of the Zab, and the Umayyads were defeated. Damascus fell to the Abbasids in April, and in August, Marwan was killed in Egypt.
