Former Goldman Sachs director Rajat Gupta is set to be sentenced by a US judge in New York later on Wednesday evening on insider trading charges. The sentence comes after a year after he was charged with passing boardroom secrets to the now-imprisoned hedge fund founder Raj Rajaratnam.

The Prosecution has sought a prison term of 8 to 10 years for the 63-year-old Gupta, who was convicted by a jury in June on three counts of securities fraud and one count of conspiracy.

Gupta, the most high-profile Wall Street executive to be convicted in the government's crackdown on insider trading, is seeking leniency from the judge, citing his otherwise unblemished career and philanthropic work.
