“I will faithfully discharge the duties of the office of prime minister of the government in accordance with the law,” he said on Tuesday, sworn in by President Mohammed Shahabuddin, in a televised ceremony held outside the parliament building in the capital, Dhaka.
The Bangladesh Nationalist Party (BNP) secured more than a two-thirds majority in last week’s elections.
Earlier, inside the parliament’s oath room, lawmakers pledged loyalty to Bangladesh as they were sworn in by Chief Election Commissioner AMM Nasir Uddin.
Foreign dignitaries, including the Pakistani foreign minister and the speaker of the Indian Parliament, were in attendance.
