WATCH: Overwhelmed PM-elect Shehbaz makes gaffe in victory speech

As the National Assembly on Sunday elected Pakistan Muslim League-Nawaz (PML-N) President Shehbaz Sharif as the 24th prime minister (PM) of the country, the PM-elect called himself the "leader of the opposition" in parliament.

Shehbaz became premier for the second time in a row after obtaining 201 votes against Pakistan Tehreek-e-Insaf's (PTI)-backed Sunni Ittehad Council (SIC) candidate Omar Ayub Khan, in a ruckus-hit session of the House.

Overwhelmed by emotions, the newly elected prime minister made the gaffe in his maiden speech on the floor of the lower house of parliament his victory.

"From the deepest core of heart, I thank those who, with their votes and love, elected me as the leader of the opposition in this House,” Shehbaz said in his victory speech.

The PML-N leader's victory was expected as he enjoyed the support of seven other parties apart from the PML-N. These parties include Pakistan Peoples Party (PPP), Muttahida Qaumi Movement-Pakistan (MQM-P), Pakistan Muslim League-Quaid (PML-Q), Balochistan Awami Party (BAP), Pakistan Muslim League-Zia (PML-Z), Istehkam-e-Pakistan Party (IPP) and National Party (NP).

With his election to the coveted post, Shehbaz has become the only politician to be elected as the PM for the second consecutive time.
