ISLAMABAD: The Senate chairmanship of Sadiq Sanjrani was challenged in a petition submitted to the Supreme Court on Thursday. 

The applicant, in the petition, has pleaded the apex court that Sanjrani's age is around 40 years-old, while the age for the interim president is 45 years in the Constitution. 

Elections for the post of chairman Senate should be held again, the petition further pleaded the court. 

The ruling PML-N lost the race to appoint their favoured candidates to the top Senate slots as Sadiq Sanjrani, an opposition-backed candidate from Balochistan, was appointed chairman.

Sanjrani who was backed by the Pakistan Peoples Party (PPP), Pakistan Tehreek-e-Insaf (PTI) and the Muttahida Qaumi Movement-Pakistan (MQM-P) secured 57 votes compared to 46 for Haq.

PPP?s Saleem Mandviwalla won the post of deputy chairman versus PkMAP?s Usman Kakar who was supported by the PML-N.
