Lahore:
The Pakistan People's Party (PPP) will field senior leader Makhdoom Amin Fahim against Pakistan Muslim League-Nawaz (PML-N) chief Nawaz Sharif for the election of the new prime minister in Parliament on June 5, rejecting a request to facilitate a unanimous vote.
Former federal minister Fahim heads the PPP Parliamentarians, the name under which the party is registered with the Election Commission.
However, the PPP's move will not affect Mr Sharif as the PML-N has a majority in the 342-member lower house of the Parliament.
PML-N leaders said Mr Sharif's election for an unprecedented third term as premier will be a mere formality.
The PPP had earlier indicated that it might vote for Sharif in order to continue its policy of reconciliation with other political parties.
When the PPP emerged the single largest party in the 2008 polls, its prime ministerial candidate, Yousuf Raza Gilani, was elected unopposed in the National Assembly.
However, most PPP leaders were of the view that their party would be further marginalised if it goes soft on the PML-N at the centre.
They believe Imran Khan's Pakistan Tehrik-e-Insaf is a potential threat to the PPP and may deprive it of its role as opposition at the centre if the PPP continues its reconciliation policy and becomes a "friendly opposition".
PPP secretary general Sardar Latif Khosa told PTI that his party was not going to leave the field open for candidates of other parties in the premier's election.
"My party is the second largest party with 38 seats in the National Assembly and it is not going to be subservient to any other party," he said.
The Pakistan Tehrik-e-Insaf, the third largest party in parliament with 31 seats, has fielded Javed Hashmi for the slot of premier.
