Former prime minister and veteran Congress leader ManmohanSingh on Tuesday filed nomination papers for a Rajya Sabha seat in Rajasthan.

Singh, earlier a Rajya Sabha member from Assam, wasaccompanied by Rajasthan Chief Minister Ashok Gehlot, deputy CM Sachin Pilotand party’s other senior leaders in the state. The seat from Rajasthan fellvacant due to the death of BJP’s Madan Lal Saini in June.

Dr Manmohan Singh’s long stint in the Rajya Sabha started in1991 when he was elected from Assam, soon after then prime minister PVNarasimha Rao inducted him to his cabinet to steer the economy. ManmohanSingh’s association with the Rajya Sabha continued for four more terms, two ofthem as the country’s prime minister.

When his term ended in June, the Congress didn’t field anycandidates because of its depleted strength in the Assam assembly after thestate elections in 2016. The Congress had only 25 legislators in the 126-memberassembly.
