Tarique Rahman, the front-runner to be the next prime minister of Bangladesh, has returned to the country after 17 years in exile ahead of landmark general elections.

The 60-year-old is the figurehead of the influential Zia family and the son of former prime minister Khaleda Zia.

The party he leads, the Bangladesh Nationalist Party (BNP), is eyeing a return to power when Bangladesh goes to the polls in the new year.

Rahman, who has lived in London since 2008, is expected to become the country's new leader if the BNP emerges as the largest party.

Rahman's return comes in the wake of former Prime Minister Sheikh Hasina being ousted last year.
