Former Telecom Minister Sukh Ram on Wednesday moved the Delhi High Court challenging his conviction and sentencing by a trial court for taking Rs 3 lakh as bribe to award a lucrative contract to a telecom firm in 1996. 86-year-old Sukh Ram, who had held the Telecom portfolio in P V Narasimha Rao's cabinet, was convicted last Thursday in a cable contract case. He was handed out five years jail term by Special CBI judge R P Pandey on Saturday and sent to jail.
