New Delhi, Aug. 2 -- Rajya Sabha MP Amar singh, who passed away in a hospital in Singapore on Saturday, was a key figure during Manmohan Singh's 10-year Government between 2004 and 2014. He played a key role in bringing together the Congress and the SP in 2008 after the Communist Party of India withdrew support following a nuclear deal with the United States.

In 2011, Amar Singh was sent to the Tihar Jail in Delhi facing charges of corruption in the infamous 'cash for vote case'. Amar Singh was accused of bribing three MPs to vote for the Manmohan Singh-led UPA1 government during the trust vote after the Left parties withdrew support from the UPA following the Indo-US Civil Nuclear Deal.
