Liu Zhijun

As Railway Minister, Liu oversaw numerous expansions of China's railway system, most notably the rapid development of China's high-speed railway. He was a figure of national praise until February 2011, when he was arrested and expelled from the Party over allegations of corruption. After the Wenzhou train collision in July 2011, in which forty people died and one hundred and ninety-two people were injured, a government report singled out his leadership as one of the main contributors to the crash and he was publicly criticized.
In April 2013, Liu was arrested on corruption charges for taking over 64 million yuan in bribes and abusing his power as Minister of Railways. He was convicted and received a death sentence with reprieve in July 2013. On 14 December 2015, Liu Zhijun's sentence was statutorily commuted to life imprisonment. The prison authorities said that he was expressing repentance and had committed no intentional offences during the reprieve period. Provided by Wikipedia
