Tarique Rahman is on course to be elected the new prime minister of Bangladesh after his centre-right Bangladesh Nationalist Party (BNP) won enough seats to secure a majority in the general election.

Rahman, 60, is the figurehead of the influential Zia family, who have dominated politics in the country for decades. Both of his parents previously served as leaders of Bangladesh.

Yet it has been far from a smooth path to the top for Rahman, whose career has been dogged by allegations of nepotism and corruption by political rivals, as well as a period of exile and his father's assassination.

His eventual ascent to chairman of the BNP came just weeks before Bangladesh headed to the polls, following the death of his mother, the country's first female prime minister Khaleda Zia.

Rahman first became active within the BNP in 2001, when he was in his mid-30s.
