China roiled by unexplained leadership shakeup as several ministers sacked

<p>Former Chinese premier Li Keqiang passed away this week at the age of 68. According to state media, he died of a heart attack. News of Li's death comes the same week that China's defence minister Li Shangfu was sacked after a two-month disappearance. The country's science & technology and finance ministers were also fired this week. For analysis of this leadership shakeup, we speak to Dr Zeno Leoni, a lecturer in defence studies at King's College London and the author of "Grand Strategy and the Rise of China: Made in America".</p>
