Emeritus Professor Ross Fitzgerald says Chinese President Xi Jinping is “utterly despotic”.
It comes amid news of new food waste laws implemented by Beijing which will see restaurants fine customers who do not finish their meals.
The legislation will also see waiters barred from encouraging customers to order too much food.
“The war on waste is just another example of him (Xi Jinping) trampling over the rights of ordinary people in China,” Professor Fitzgerald told Sky News host Chris Smith.
“The president is utterly utterly despotic.”
