Backgrounder: Egyptian PMs after 2011 revolution

Egyptian Prime Minster Ibrahim Mahlab and his cabinet resigned on Saturday and the resignation was accepted by President Abdel-Fattah al-Sisi, according to a statement from his office.

The statement said that Sisi received the resignation together with a detailed report about the government's performance during the recent period.

Mahlab was first sworn in as the prime minister in March 2014 and then he organized a presidential election through which Sisi, the previous army chief, stepped up as president later in May that year.

Egypt has been plagued by political turmoil and frequent cabinet reshuffles since the 2011 revolution that toppled former leader Hosni Mubarak. In the four years following the upheaval, Egypt has witnessed five prime ministers, unprecedentedly many in such a short period.

The following is a list of the Egyptian prime ministers after the 2011 uprising which ended Mubarak's 30-year rule.

Ibrahim Mahlab (March 1, 2014 to Sept. 12, 2015)

Mahlab and his cabinet took office in March 2014. He was a senior member of Mubarak's former ruling National Democratic Party and served as the Minister of Housing in his predecessor Hazem al-Beblawi's cabinet.

He was tasked with forming an interim government following the surprising resignation of Beblawi's government. He vowed to "work together to restore security and safety to Egypt and crush terrorism in all corners of the country." He also vowed to reinvigorate Egyptian ailing economy as he took office.

Hazem al-Beblawi (July 9, 2013 to March 1, 2014)

Being a prominent economist and politician, Beblawi was appointed as prime minister in the transitional government by then Egypt's former interim President Adli Mansour on July 9, 2013.

He had previously served as deputy prime minister and minister of finance in 2011. In his academic career, Beblawi was a lecturer at Alexandria University and taught economic courses in several universities in Egypt and abroad. He announced his resignation on Feb. 24, 2014.

Hesham Qandil (Aug. 2, 2012 to July 8, 2013)

Qandil was appointed as prime minister by ousted Islamist President Mohamed Morsi on July 24, 2012, one month after Morsi won the country's first democratic presidential elections.

Qandil had previously served as minister of water resources and irrigation from 2011 to 2012. He was Egypt's youngest prime minister since 1954.

Being Morsi's prime minister, the man was arrested and indicted several months after he resigned on July 8, 2013. He was released in 2014 after a court accepted his appeal and annulled the one-year sentence against him.

Kamal al-Ganzouri (Dec. 7, 2011 to Aug. 2, 2012)

Ganzouri was appointed by the Supreme Council of the Armed Forces (SCAF) that was in charge of the country following the ouster of Mubarak in February 2011. He also served as prime minister under Mubarak from 1996 to 1999, during which he was branded as the "minister of the poor" as he has always been in support of the poor citizens.

Ganzouri's government resigned on June 26, 2012 to make way for the new government after Morsi was elected as president of Egypt.

Essam Sharaf (March 3, 2011 to Dec. 2, 2011)

Sharaf was the first post-revolution prime minister and he was appointed by then Egypt's governing military council, the SCAF, on March 3, 2011.

Sharaf was present and active at Tahrir Square protests during the 2011 anti-Mubarak revolution, which endeared him to pro-democracy activists and recommended his premiership.

His leadership, however, was largely viewed as a cabinet with a ceremonial role orchestrated by the SCAF rather than having any true executive power.

After the inability to address a massive demonstration in Tahrir Square on Nov. 18, 2011, and failure of several policy reforms, Sharaf submitted his resignation to the SCAF on Nov.21, 2011. Endit
