Kerala Governor Arif Mohammad Khan on Wednesday doubled down on claims of a "nexus" between the ruling CPIM - via the Students' Federation of India, its student wing - and the Popular Front of India banned by the Union Home Ministry under anti-terror law UAPA. Speaking to NDTV, Mr Khan launched a sharp attack on Chief Minister Pinarayi Vijayan's administration and referred to what he said is now a common phrase in the southern state - "during the day they (the Kerala government) are with SFI and, in the night, work for PFI". "The evidence I have (of his claims of a SFI-PFI "nexus") is what I hear from the people of Kerala. Now I can't give you exact names... but the (central) agencies have this information," the Governor - who is at loggerheads with the state on various issues, including appointments to state-run universities - said.
