He said there is no truth in claims that the 'establishment' backed him.
While speaking to the media in Quetta on Sunday, Sanjrani said senators from across Pakistan were in favour of him being elected as the chairperson of the Upper House of Parliament.
He added the efforts of assembly members and chief minister Balochistan elected him and five other independent candidates. It was the group of these six that mustered support of senators across Pakistan, he added.
Sanjrani thanked the senators, Pakistan Tehreek-e-Insaf chairperson Imran Khan and Pakistan Peoples Party co-chairperson Asif Ali Zardari for their support.
