Former Indian Prime Minister Manmohan Singh passed away on Thursday: During Congress's last stint as the ruling government, the party witnessed some tough economic challenges. And one of the biggest came in 2012, as the aftershocks of the 2008 US financial crisis continued to send shockwaves across global economies. In India, all eyes turned to the then Prime Minister of the country, Manmohan Singh, for the policy decisions that took centre stage at that time.
