Kerala Governor Arif Mohammad Khan on November 07 challenged the ruling CPI(M) members for an open debate over the appointment of Vice Chancellors in Universities. Speaking to media persons, Khan said, "Don't hold it (CPIM) march on Nov 15, hold it on a day when I'm in Raj Bhavan. I'll come there, let's have a public debate. VCs are being stopped from performing their duty, law & order issues are being created, I'm being threatened with dire consequences." "They have initiated the process of collapse of constitutional machinery. I would urge them to go ahead, create more problems, barge into Raj Bhavan if you have the guts, attack me on the road. CM says that he doesn't know who I am, I know who he is," he added.
