Pakistan's former president, Asif Ali Zardari, is set to become the country's 14th president after today's elections.
Zardari, who is expected to replace the incumbent Dr Arif Alvi, also happens to be the husband of assassinated Pakistani Prime Minister Benazir Bhutto. He is a co-chairman of the Pakistan Peoples Party (PPP).
The 68-year-old leader is also backed by the coalition government led by the Pakistan Muslim League-Nawaz (PML-N), and it's almost certain that he will win Saturday's election.
Zardari, who was president from 2008 to 2013, will also be the first civilian to be elected president for a second time.
Zardari's opponent is Mahmood Khan Achakzai, leader of the Pashtoonkhwa Milli Awami Party (PkMAP).
The ruling coalition is confident that Zardari will be elected as the parties have a majority in the Senate, National Assembly, Punjab Assembly, Sindh Assembly and Balochistan Assembly.
The opposition only has a majority in the Khyber-Pakhtunkhwa Assembly.
