Minister for Religious Affairs Syed Hamid Saeed Kazmi on Thursday questioned the authenticity of the letter written by a Saudi Prince to Supreme Court and his ministry, alleging corruption in the hiring process of residential buildings. There is a big question mark over the authenticity of the letter as it was not sent to Supreme Court and the ministry through proper channel. Protocol-wise, such correspondence takes place through diplomatic channels like embassies and foreign offices of the concerned countries, he said. The minister was addressing a news conference along with Secretary of Religious Affairs, Agha Sarwar Raza Qazlbash here at the Press Information Department.
