Eight votes were rejected, seven of which were cast in favour of opposition candidate Yousaf Raza Gilani.
The opposition challenged the rejection of the seven votes. Both sides gave their opinion while addressing the presiding officer. The objection raised by the opposition was not sustained by the presiding officer who said that Sadiq Sanjrani was elected as the chairman.
Sanjrani took oath as the Senate chief amid sloganeering from opposition benches.
